sentences: The Hilina Slump is a 5,000 cubic mile (20,000 kilometre³) section of the Big Island of Hawaii on the south flank of the Kilauea volcano.
 Between 1990 and 1993, Global Positioning System measurements showed a southward displacement of the south flank of Kilauea up to approximately 10 centimeters per year.
 The slump has the potential of breaking away at a faster pace in the form of an underwater landslide.
 In Hawaii, landslides of this nature are called debris avalanches.
 If the entire Hilina Slump were to slide into the ocean at once, it could cause an earthquake in excess of a 9 in magnitude, and a megatsunami.
 Previous megatsunamis in Hawaii 110,000 years ago caused by similar geological phenomena may have created waves 1,600 feet (500 m) tall.
Kīlauea Military Camp (KMC) is operated as a Morale, Welfare and Recreation (MWR) facility on Hawai‘i Island, also known as the Big Island, in Hawaiʻi.
 It is located inside Hawaiʻi Volcanoes National Park.
 This U.S. Department of Defense (DOD) facility is at an elevation of 4000 feet, within walking distance from Kilauea Volcano, the world’s most active volcano.
Aguas Calientes Volcano or Cerro Aguas Calientes, also called Simba, is a cone-shaped stratovolcano located 5 km east of the Lascar volcano and 10 km north of Laguna Lejía, Chile.
 Aguas Calientes is located within a 500 km2 area where the Cordón de Puntas Negras and the Cordón Chalviri volcanic chains intersect.
 The volcano is constructed from andesite and dacite containing hornblende and also anhydrite and its pyroclastics are all older than Lascar.
 The volcano has a diameter of about 7 km .
 Some xenoliths of calc-alkaline material are found in Aguas Calientes lavas, and magma mixing has generated lavas containing andesite inclusions in dacites.
 One eruption of Aguas Calientes postdates the first centre of Lascar and was originally linked to the Lascar Piedras Grandes eruption, before sampling on the deposits of this eruption indicated a relationship with the Lascar volcano itself.
 Effusion of lava ceased after the cone was built.
 One summit lava flow may be of Holocene age, but no evidence of historical activity is found (González-Ferrán 1985).
Hawaiʻ i Volcanoes National Park, established on August 1, 1916, is an American National Park located in the U.S. state of Hawaii on the island of Hawaii.
 It encompasses two active volcanoes: Kīlauea, one of the world's most active volcanoes, and Mauna Loa, the world's most massive shield volcano.
 The park delivers scientists insight into the birth of the Hawaiian Islands and ongoing studies into the processes of volcanism.
 For visitors, the park offers dramatic volcanic landscapes as well as glimpses of rare flora and fauna.
Devastation Trail is a trail at Hawaiʻi Volcanoes National Park.
 The paved trail allows visitors to explore the site of 1959 eruption of Kīlauea Iki crater.
The 1975 Hawaii earthquake occurred on November 29 with a moment magnitude of 7.4 and a maximum Mercalli intensity of VIII ("Severe").
 The shock affected several of the Hawaiian Islands and resulted in the deaths of two people and up to 28 injured.
 Significant damage occurred in the southern part of the Big Island totaling $4–4.1 million and it also triggered a small brief eruption of Kilauea volcano.
On May 18, 1980, a major volcanic eruption occurred at Mount St. Helens, a volcano located in Skamania County, in the state of Washington, United States.
 The eruption (a VEI 5 event) was the only significant volcanic eruption to occur in the contiguous 48 U.S. states since the 1915 eruption of Lassen Peak in California.
 However, it has often been declared as the most disastrous volcanic eruption in United States history.
 The eruption was preceded by a two-month series of earthquakes and steam-venting episodes, caused by an injection of magma at shallow depth below the volcano that created a large bulge and a fracture system on the mountain's north slope.
Cotopaxi National Park (Spanish: "Parque Nacional Cotopaxi" ) is a protected area in Ecuador situated in the Cotopaxi Province, Napo Province and Pichincha Province, roughly 50 km south of Quito.
 The Cotopaxi volcano (supposedly meaning smooth neck of the moon) that lends its name to the park is located within its boundaries, together with two others: the dormant Rumiñawi volcano to its north-west and the historical Sincholagua volcano (last major eruption: 1877) to the south east.
 Cotopaxi is among the highest active volcanoes in the world; its last significant eruption took place in 1904.
Piton de la Fournaise (French): "Peak of the Furnace" is a shield volcano on the eastern side of Réunion island (a French department) in the Indian Ocean.
 It is currently one of the most active volcanoes in the world, along with Kīlauea in the Hawaiian Islands (Pacific Ocean), Stromboli, Etna (Italy) and Mount Erebus in Antarctica.
 A previous eruption began in August 2006 and ended in January 2007.
 The volcano erupted again in February 2007, on 21 September 2008, on 9 December 2010, which lasted for two days.
 and on 1 August 2015.
 The most recent eruption began on 14 July 2017.
 The volcano is located within Réunion National Park, a World Heritage site.
The 2011 eruption of Grímsvötn was an eruption in Grímsvötn, Iceland's most active volcano, which caused disruption to air travel in Northwestern Europe from 22–25 May 2011.
 The last eruption of Grímsvötn was in 2004, with the previous most powerful eruptions in 1783, 1873 and 1902.
 The Grímsvötn eruption was the largest eruption in Iceland for 50 years.
