The top of the seamount is about 975 m ( 3,000 ft ) below sea level. This seamount is on the flank of Mauna Loa, the largest shield volcano on Earth. Lōihi, meaning `` long '' in Hawaiian, is the newest volcano in the Hawaiian - Emperor seamount chain, a string of volcanoes that stretches over 5,800 km ( 3,600 mi ) northwest of Lōʻihi. Unlike most active volcanoes in the Pacific Ocean that make up the active plate margins on the Pacific Ring of Fire, Lōʻihi and the other volcanoes of the Hawaiian - Emperor seamount chain are hotspot volcanoes and formed well away from the nearest plate boundary. Volcanoes in the Hawaiian Islands arise from the Hawaii hotspot, and as the youngest volcano in the chain, Lōihi is the only Hawaiian volcano in the deep submarine preshield stage of development. Lōihi began forming around 400,000 years ago and is expected to begin emerging above sea level about 10,000 -- 100,000 years from now. At its summit, Lōʻihi Seamount stands more than 3,000 m ( 10,000 ft ) above the seafloor, making it taller than Mount St. Helens was before its catastrophic 1980 eruption. A diverse microbial community resides around Lōihi 's many hydrothermal vents. In the summer of 1996, a swarm of 4,070 earthquakes was recorded at Lōʻihi. This series included more earthquakes than any other swarm in Hawaiian recorded history. The swarm altered 10 to 13 square kilometres ( 4 to 5 sq mi ) of the seamount 's summit ; one section, Pele 's Vents, collapsed entirely upon itself and formed the renamed Pele 's Pit. The volcano has remained relatively active since the 1996 swarm and is monitored by the National Oceanic and Atmospheric Administration ( NOAA ) and the United States Geological Survey ( USGS ). The Hawaii Undersea Geological Observatory ( HUGO ) provided real - time data on Lōʻihi between 1997 and 2002. Lōʻihi last erupted in 1996, before the earthquake swarm of that summer.

It is the newest volcano created by the Hawaiʻi hotspot in the extensive Hawaiian - Emperor seamount chain. The distance between the summit of the older Mauna Loa and the summit of Lōʻihi is about 80 km ( 50 mi ), which is, coincidentally, also the approximate diameter of the Hawaiʻi hotspot. Lōʻihi consists of a summit area with three pit craters, an 11 km ( 7 mi ) long rift zone extending north from the summit, and a 19 km ( 12 mi ) long rift zone extending south - southeast from the summit. The summit 's pit craters are named West Pit, East Pit, and Pele 's Pit. Pele 's Pit is the youngest of this group and is located at the southern part of the summit. The walls of Pele 's Pit stand 200 m ( 700 ft ) high and were formed in July 1996 when its predecessor, Pele 's Vent, a hydrothermal field near Lōʻihi 's summit, collapsed into a large depression. The thick crater walls of Pele 's Pit -- averaging 20 m ( 70 ft ) in width, unusually thick for Hawaiian volcanic craters -- suggest its craters have filled with lava multiple times in the past. Bathymetric mapping of Lōʻihi ; the arrow points to Pele 's Pit. Lōihi 's north -- south trending rift zones create a distinctive elongated shape, from which the volcano 's Hawaiian name, meaning `` long '', derives. The north rift zone consists of a longer western portion and a shorter eastern rift zone. Observations show that both the north and south rift zones lack sediment cover, indicating recent activity. A bulge in the western part of the north rift zone contains three 60 -- 80 m ( 200 -- 260 ft ) cone - shaped prominences. Until 1970, Lōihi was thought to be an inactive volcano that had been transported to its current location by sea - floor spreading. The seafloor under Hawaii is 80 -- 100 million years old and was created at the East Pacific Rise, an oceanic spreading center where new sea floor forms from magma that erupts from the mantle. New oceanic crust moves away from the spreading center. Over a period of 80 -- 100 million years, the sea floor under Hawaii moved from the East Pacific Rise to its present location 6,000 km ( 4,000 mi ) west, carrying ancient seamounts with it. When scientists investigated a series of earthquakes off Hawaii in 1970, they discovered that Lōihi was an active member of the Hawaiian - Emperor seamount chain. Three dimensional rendering of the Seamount Lōʻihi is built on the seafloor with a slope of about five degrees. Its northern base on the flank of Mauna Loa is 1,900 m ( 6,200 ft ) below sea level, but its southern base is a more substantial 4,755 m ( 15,600 ft ) below the surface. Thus, the summit is 931 m ( 3,054 ft ) above the seafloor as measured from the base of its north flank, but 3,786 m ( 12,421 ft ) high when measured from the base of its southern flank. Lōihi is following the pattern of development that is characteristic of all Hawaiian volcanoes. Geochemical evidence from Lōihi lavas indicates that Lōihi is in transition between the preshield and shield volcano stage, providing valuable clues to the early development of Hawaiian volcanoes. In the preshield stage, Hawaiian volcanoes have steeper sides and a lower level of activity, producing an alkali basalt lava. Continued volcanism is expected to eventually create an island at Lōihi. Lōʻihi experiences frequent landslides ; the growth of the volcano has destabilized its slopes, and extensive areas of debris inhabit the steep southeastern face. Similar deposits from other Hawaiian volcanoes indicate that landslide debris is an important product of the early development of Hawaiian volcanoes. Lōʻihi is predicted to rise above the surface in 10,000 to 100,000 years. Age and growth A sample of basalt pillow lava collected from Lōʻihi, at 1,180 metres below sea level Radiometric dating was used to determine the age of rock samples from Lōʻihi. The Hawaii Center for Volcanology tested samples recovered by various expeditions, notably the 1978 expedition, which provided 17 dredge samples. Most of the samples were found to be of recent origin ; the oldest dated rock is around 300,000 years old. Following the 1996 event, some young breccia was also collected. Based on the samples, scientists estimate Lōʻihi is about 400,000 years old. The rock accumulates at an average rate of 3.5 mm ( 0.14 in ) per year near the base, and 7.8 mm ( 0.31 in ) near the summit. If the data model from other volcanoes such as Kīlauea holds true for Lōʻihi, 40 % of the volcano 's mass formed within the last 100,000 years. Assuming a linear growth rate, Lōihi is 250,000 years old. However, as with all hotspot volcanoes, Lōihi 's level of activity has increased with time ; therefore, it would take at least 400,000 years for such a volcano to reach Lōihi 's mass. As Hawaiian volcanoes drift northwest at a rate of about 10 cm ( 4 in ) a year, Lōʻihi was 40 km ( 25 mi ) southeast of its current position at the time of its initial eruption. Activity Lōihi is a young and fairly active volcano, although less active than nearby Kīlauea. In the past few decades, several earthquake swarms have been attributed to Lōihi, the largest of which are summarized in the table below. The volcano 's activity is now known to predate scientific record keeping of its activity, which commenced in 1959. Most earthquake swarms at Lōihi have lasted less than two days ; the two exceptions are the 1991 -- 92 earthquake, lasting several months, and the 1996 event, which was shorter but much more pronounced. Both of the earthquakes followed a pattern of activity that began on the flank and migrated to the summit. The 1996 event was directly observed by an autonomous ocean bottom observatory ( OBO ), allowing scientists to calculate the depth of the earthquakes as 6 km ( 4 mi ) to 8 km ( 5 mi ) below the summit, approximating to the position of Lōihi 's extremely shallow magma chamber. This is evidence that Lōʻihi 's seismicity is volcanic in origin. The low - level seismic activity documented on Lōihi since 1959 has shown that between two and ten earthquakes per month are traceable to the summit. Earthquake swarm data have been used to analyze how well Lōihi 's rocks propagate seismic waves and to investigate the relationship between earthquakes and eruptions. This low level activity is periodically punctuated by large swarms of earthquakes, each swarm comprising up to hundreds of earthquakes. The majority of the earthquakes are not distributed close to the summit, though they follow a north -- south trend. Rather, most of the earthquakes occur in the southwest portion of Lōʻihi. The largest recorded swarms took place on Lōihi in 1971, 1972, 1975, 1991 -- 92 and 1996. The nearest seismic station is around 30 km ( 20 mi ) from Lōʻihi, on the south coast of Hawaii. Seismic events that have a magnitude under 2 are recorded often, but their location can not be determined precisely as it can for larger events. In fact, HUGO ( Hawaii Undersea Geological Observatory ), positioned on Lōihi 's flank, detected ten times as many earthquakes as were recorded by the Hawaiian Volcano Observatory ( HVO ) seismic network. 1996 earthquake swarm Major Events Year ( s ) Summary Evidence of eruption in early 1996, and large, well - recorded earthquake swarm in the summer. Started on February 25, 1996, and lasted until August 9, 1996. 1991 An OBO positioned on the seamount to track a recent earthquake swarm collected evidence of deflation, possibly due to magma withdrawal. 1986 Possible eruption, occurred on September 20, 1986 ( one day ). 1984 -- 85 Nine events of magnitude 3 or greater, measuring between 3.0 and 4.2, were recorded from November 11, 1984, to January 21, 1985. Eruption possible, but uncertain. Prominent earthquake swarm from August 24, 1975, to November 1975. 1971 -- 72 Possible eruption from September 17, 1971, to September 1972. Eruption uncertain. 1952 An earthquake swarm on Lōʻihi in 1952 was the event that first brought attention to the volcano, previously thought extinct. 50 BC ± 1000 Confirmed ancient eruption 5050 BC ± 1000 Confirmed ancient eruption 7050 BC ± 1000 Confirmed ancient eruption, most likely on the east flank This table indexes only possible volcanic eruptions and major events. Lōʻihi has also been the site of multiple earthquake swarms occurring on a nearly semi-annual basis. The largest amount of activity recorded for the Lōihi seamount was a swarm of 4,070 earthquakes between July 16 and August 9, 1996. This series of earthquakes was the largest recorded for any Hawaiian volcano to date in both amount and intensity. Most of the earthquakes had moment magnitudes of less than 3.0. `` Several hundred '' had a magnitude greater than 3.0, including more than 40 greater than 4.0 and a 5.0 tremor. The final two weeks of the earthquake swarm were observed by a quick response cruise launched in August 1996. The National Science Foundation funded an expedition by University of Hawaii scientists, led by Frederick Duennebier, that began investigating the swarm and its origin in August 1996. The scientists ' assessment laid the groundwork for many of the expeditions that followed. Follow - up expeditions to Lōʻihi took place, including a series of manned - submersible dives in August and September. These were supplemented by a great deal of shore - based research. Fresh rock collected during the expedition revealed that an eruption occurred before the earthquake swarm. Submersible dives in August were followed by NOAA - funded research in September and October 1996. These more detailed studies showed the southern portion of Lōʻihi 's summit had collapsed, a result of a swarm of earthquakes and the rapid withdrawal of magma from the volcano. A crater 1 km ( 0.6 mi ) across and 300 m ( 1,000 ft ) deep formed out of the rubble. The event involved the movement of 100 million cubic meters of volcanic material. A region of 10 to 13 km ( 4 to 5 sq mi ) of the summit was altered and populated by bus - sized pillow lava blocks, precariously perched along the outer rim of the newly formed crater. `` Pele 's Vents, '' an area on the southern side, previously considered stable, collapsed completely into a giant pit, renamed `` Pele 's Pit ''. Strong currents make submersible diving hazardous in the region. The researchers were continually met by clouds of sulfide and sulfate. The sudden collapse of Pele 's Vents caused a large discharge of hydrothermal material. The presence of certain indicator minerals in the mixture suggested temperatures exceeded 250 ° C, a record for an underwater volcano. The composition of the materials was similar to that of black smokers, the hydrothermal vent plumes located along mid-ocean ridges. Samples from mounds built by discharges from the hydrothermal plumes resembled white smokers. The studies demonstrated that the most volcanically and hydrothermally active area was along the southern rift. Dives on the less active northern rim indicated that the terrain was more stable there, and high lava columns were still standing upright. A new hydrothermal vent field ( Naha Vents ) was located in the upper - south rift zone, at a depth of 1,325 m ( 4,350 ft ). Recent activity Lōʻihi has remained largely quiet since the 1996 event ; no activity was recorded from 2002 to 2004. The seamount showed signs of life again in 2005 by generating an earthquake bigger than any previously recorded there. USGS - ANSS ( Advanced National Seismic System ) reported two earthquakes, magnitudes 5.1 and 5.4, on May 13 and July 17. Both originated from a depth of 44 km ( 27 mi ). On April 23, a magnitude 4.3 earthquake was recorded at a depth of approximately 33 km ( 21 mi ). Between December 7, 2005, and January 18, 2006, a swarm of around 100 earthquakes occurred, the largest measuring 4 on the Moment magnitude scale and 12 km ( 7 mi ) to 28 km ( 17 mi ) deep. Another earthquake measuring 4.7 was later recorded approximately midway between Lōihi and Pāhala ( on the south coast of the Hawaii ( Island ) ). Exploration Early work Expedition Timeline Date Study ( most on R / V Kaʻimikai - o - Kanaloa and with Pisces V ) 1940 Lōʻihi 's first depiction on a map was on Survey Chart 4115, compiled by the US Coast and Geodetic Survey in 1940. 1978 An expedition formed to study intense seismic activity in the region at the time. Data collected was the first solid evidence of the volcano being active. 1979 More extensive sampling ( 17 dredgehauls ) from this expedition seemed to confirm the 1970 results. 1980 Extensive hydrothermal fields found, yielding more evidence.

October 2006 October 2007 October 2008 October 2009 FeMO ( Fe - Oxidizing Microbial Observatory ) cruises to investigate iron - oxidizing microbes at Lōʻihi. Much is learned about Lōʻihi 's microbial community. Lōʻihi Seamount 's first depiction on a map was on Survey Chart 4115, a bathymetric rendering of part of Hawaiʻi compiled by the US Coast and Geodetic Survey in 1940. At the time, the seamount was non-notable, being one of many in the region. A large earthquake swarm first brought attention to it in 1952. That same year, geologist Gordon A. MacDonald hypothesized that the seamount was actually an active submarine shield volcano, similar to the two active Hawaiian volcanoes, Mauna Loa and Kīlauea. Macdonald 's hypothesis placed the seamount as the newest volcano in the Hawaiian - Emperor seamount chain, created by the Hawaiʻi hotspot. However, because the earthquakes were oriented east -- west ( the direction of the volcanic fault ) and there was no volcanic tremor in seismometers distant from the seamount, Macdonald attributed the earthquake to faulting rather than a volcanic eruption. R / V ( research vessel ) Kaʻimikai - o - Kanaloa ( KoK ) launching Pisces V, a battery - powered submersible. The R / V KoK is the support ship for the Hawaiʻi Undersea Research Laboratory ( HURL ). Geologists suspected the seamount could be an active undersea volcano, but without evidence the idea remained speculative. The volcano was largely ignored after the 1952 event, and was often mislabeled as an `` older volcanic feature '' in subsequent charts. Geologist Kenneth O. Emery is credited with naming the seamount in 1955, describing the long and narrow shape of the volcano as Loihi. The Hawaiian word lōʻihi means `` long ''. In 1978, an expedition studied intense, repeated seismic activity known as earthquake swarms in and around the Lōʻihi area. Rather than finding an old, extinct seamount, data collected revealed Lōʻihi to be a young, possibly active volcano. Observations showed the volcano to be encrusted with young and old lava flows. Fluids erupting from active hydrothermal vents were also found. In 1978, a US Geological Survey research ship collected dredge samples and photographed Lōʻihi 's summit with the goal of studying whether Lōʻihi is active. Analysis of the photos and testing of pillow lava rock samples appeared to show that the material was `` fresh '', yielding more evidence that Lōʻihi is still active. An expedition from October 1980 to January 1981 collected further dredge samples and photographs, providing additional confirmation. Studies indicated that the eruptions came from the southern part of the rift crater. This area is closest to the Hawaiʻi hotspot, which supplies Lōʻihi with magma. Following a 1986 seismic event, a network of five ocean bottom observatories ( OBOs ) were deployed on Lōʻihi for a month. Lōʻihi 's frequent seismicity makes it an ideal candidate for seismic study through OBOs. In 1987, the submersible DSV Alvin was used to survey Lōʻihi. Another autonomous observatory was positioned on Lōʻihi in 1991 to track earthquake swarms. 1996 to present The bulk of information about Lōʻihi comes from dives made in response to the 1996 eruption. In a dive conducted almost immediately after seismic activity was reported, visibility was greatly reduced by high concentrations of displaced minerals and large floating mats of bacteria in the water. The bacteria that feed on the dissolved nutrients had already begun colonizing the new hydrothermal vents at Pele 's Pit ( formed from the collapse of the old ones ), and may be indicators of the kinds of material ejected from the newly formed vents. They were carefully sampled for further analysis in a laboratory. An OBO briefly sat on the summit before a more permanent probe could be installed. Repeated multibeam bathymetric mapping was used to measure the changes in the summit following the 1996 collapse. Hydrothermal plume surveys confirmed changes in the energy, and dissolved minerals emanating from Lōʻihi. Hawaiʻi Undersea Research Laboratory, HURL 's 2,000 m ( 6,562 ft ) submersible Pisces V allowed scientists to sample the vent waters, microorganisms and hydrothermal mineral deposits. Since 2006, the Fe - Oxidizing Microbial Observatory ( FeMO ), funded by the National Science Foundation and Microbial Observatory Program, has led cruises to Lōʻihi investigate its microbiology every October. The first cruise, on the ship R / V Melville and exploiting the submersible JASON2, lasted from September 22 to October 9. These cruises study the large number of Fe - oxidizing bacteria that have colonized Lōʻihi. Lōʻihi 's extensive vent system is characterized by a high concentration of CO2 and Iron, while being low in sulfide. These characteristics make a perfect environment for iron - oxidizing bacteria, called FeOB, to thrive in. Ocean bottom observatory ( OBO ) at Pele 's Vents HUGO ( Hawaiʻi Undersea Geological Observatory ) In 1997, scientists from the University of Hawaiʻi installed an ocean bottom observatory ( OBO ) on the summit of Lōʻihi Seamount. The submarine observatory was nicknamed HUGO, ( Hawaiʻi Undersea Geological Observatory ). HUGO was connected to the shore, 34 km ( 21 mi ) away, by a fiber optic cable. It gave scientists real - time seismic, chemical and visual data about the state of Lōʻihi, which had by then become an international laboratory for the study of undersea volcanism. The cable that provided HUGO with power and communications broke in October 1998, effectively shutting it down. On January 19 of the following year, HUGO was visited by Pisces V. The observatory functioned for four years before it went dead again in 2002.

Areas of extensive hydrothermal venting are found on Lōʻihi 's crater floor and north slope, and along the summit of Lōʻihi itself. Active hydrothermal vents were first discovered at Lōʻihi in the late 1980s. These vents are remarkably similar to those found at the mid-ocean ridges, with similar composition and thermal differences. The two most prominent vent fields are at the summit : Pele 's Pit ( formally Pele 's Vents ) and Kapo 's Vents. They are named after the Hawaiian deity Pele and her sister Kapo. These vents were considered `` low temperature vents '' because their waters were only about 30 ° C. The volcanic eruption of 1996 and the creation of Pele 's Pit changed this, and initiated high temperature venting ; exit temperatures were measured at 77 ° C in 1996. Microorganisms The vents lie 1,100 m ( 3,600 ft ) to 1,325 m ( 4,347 ft ) below the surface, and range in temperature from 10 to over 200 ° C. The vent fluids are characterized by a high concentration of CO ( up to 17 mM ) and Fe ( Iron ), but low in sulfide. Low oxygen and pH levels are important factors in supporting the high amounts of Fe ( iron ), one of the hallmark features of Lōʻihi. These characteristics make a perfect environment for iron - oxidizing bacteria, called FeOB, to thrive in. An example of these species is Mariprofundus ferrooxydans, sole member of the class Zetaproteobacteria. The composition of the materials was similar to that of black smokers, that are a habitat of archaea extremophiles. Dissolution and oxidation of the mineral observed over the next two years suggests the sulfate is not easily preserved. A diverse community of microbial mats surround the vents and virtually cover Pele 's Pit. The Hawaiʻi Undersea Research Laboratory ( HURL ), NOAA 's Research Center for Hawaiʻi and the Western Pacific, monitors and researches the hydrothermal systems and studies the local community. The National Science Foundation ( NSF ) funded an extremophile sampling expedition to Lōʻihi in 1999. Microbial mats surrounded the 160 ° C vents, and included a novel jelly - like organism. Samples were collected for study at NSF 's Marine Bioproducts Engineering Center ( MarBEC ). In 2001, Pisces V collected samples of the organisms and brought them to the surface for study. NOAA 's National Undersea Research Center and NSF 's Marine Bioproducts Engineering Center are cooperating to sample and research the local bacteria and archaea extremophiles. The fourth FeMO ( Fe - Oxidizing Microbial Observatory ) cruise occurred during October 2009. Macroorganisms Marine life inhabiting the waters around Lōʻihi is not as diverse as life at other, less active seamounts. Fish found living near Lōʻihi include the Celebes monkfish ( Sladenia remiger ), and members of the Cutthroat eel family, Synaphobranchidae. Invertebrates identified in the area include two species endemic to the hydrothermal vents, a bresiliid shrimp ( Opaepele loihi ) of the family Alvinocarididae ( described in 1995 ), and a tube or pogonophoran worm. Dives conducted after the 1996 earthquake swarms were unable to find either the shrimp or the worm, and it is not known if there are lasting effects on these species. From 1982 to 1992, researchers in Hawaiʻi Undersea Research Laboratory submersibles photographed the fish of Lōʻihi Seamount, Johnston Atoll, and Cross Seamount at depths between 40 m ( 130 ft ) and 2,000 m ( 6,600 ft ). A small number of species identified at Lōʻihi were newly recorded sightings in Hawaiʻi, including the Tassled coffinfish ( Chaunax fimbriatus ), and the Celebes monkfish.
