As-Safa (Arabic: الصفا‎ ‎ , "Aṣ-Ṣafā" ), also known as Tulul al-Safa (تلول الصفا , "Tulūl Eṣ-Ṣafā" ), Arabic for "Al-Safa hills", is a hilly region which lies in southern Syria, north-east of Jabal Al-Arab volcanic plateau.
 It consists of a basaltic lava field of volcanic origin, covering an area of 220 square kilometres, and contains at least 38 cinder cones.
 This volcanic field lies within the northern part of the massive alkaline Harrat Ash Shamah volcanic field that extends from southern Syria, through eastern Jordan to Saudi Arabia.
 The region is extremely scarce in water.
 A boiling lava lake was observed in the Es Safa volcanic area in the middle of the 19th century (see Erta Ale in Ethiopia and Puʻu ʻŌʻō in Hawaii for reference).
The Croscat (] ) is a volcano in the comarca of Garrotxa, Catalonia, Spain.
 It is both the youngest and highest volcano in the Iberian Peninsula, with the last eruption dated back to about 14,000 years Before Present.
 The volcanic cone has a horseshoe shape and its northeastern flank was quarried for volcanic gravel until the early 1990s, exposing the internal structure of the cone from top to bottom.
 The volcano is located in the Garrotxa volcanic field, a Quaternary volcanic field also known as Olot volcanic field, as part of the protected area of the Garrotxa Volcanic Zone Natural Park.
Puʻ u ʻ Ōʻ ō (often written Puu Oo, ] ) is a volcanic cone in the eastern rift zone of the Kīlauea volcano of the Hawaiian Islands.
 Puʻ u ʻ Ōʻ ō has been erupting continuously since January 3, 1983, making it the longest-lived rift-zone eruption of the last two centuries.
Mauna Ulu is a volcanic cone in the eastern rift zone of the Kīlauea volcano on the island of Hawaii.
 It falls within the bounds of Volcanoes National Park.
 Mauna Ulu was in a state of eruption from May 1969 to July 1974.
Kaimū was a small town in the Puna District on Island of Hawaiʻ i that was completely destroyed by an eruptive flow of lava from the Kūpaʻianahā vent of the Kīlauea volcano in 1990.
 In Hawaiian, "kai mū" means "gathering [at the] sea" as to watch surfing.
 The lava flow that destroyed Kaimū and nearby Kalapana erupted from the southeast rift zone of Kīlauea.
The Kaʻ ū Desert is a leeward desert in the district of Kaʻ ū, the southernmost district on the Big Island of Hawaii, and is made up mostly of dried lava remnants, volcanic ash, sand and gravel.
 The desert covers an area of the Kīlauea Volcano along the Southwest rift zone.
 The area lacks any vegetation, mainly due to acid rainfall.
A rift zone is a feature of some volcanoes, especially shield volcanoes, in which a linear series of cracks (or rifts) develops in a volcanic edifice, typically forming into two or three well-defined regions along the flanks of the vent.
 Believed to be primarily caused by internal and gravitational stresses generated by magma emplacement within and across various regions of the volcano, rift zones allow the intrusion of magmatic dykes into the slopes of the volcano itself.
 The addition of these magmatic materials usually contributes to the further rifting of the slope, in addition to generating fissure eruptions from those dykes that reach the surface.
 It is the grouping of these fissures, and the dykes that feed them, that serves to delineate where and whether a rift zone is to be defined.
 The accumulated lava of repeated eruptions from rift zones along with the endogenous growth created by magma intrusions causes these volcanoes to have an elongated shape.
 Perhaps the best example of this is Mauna Loa, which in Hawaiian means "long mountain", and which features two very well defined rift zones extending tens of kilometers outward from the central vent.
Kīlauea ( , ; ] ) is a currently active shield volcano in the Hawaiian Islands, and the most active of the five volcanoes that together form the island of Hawaiʻ i.
 Located along the southern shore of the island, the volcano is between 300,000 and 600,000 years old and emerged above sea level about 100,000 years ago.
 It is the second youngest product of the Hawaiian hotspot and the current eruptive center of the Hawaiian–Emperor seamount chain.
 Because it lacks topographic prominence and its activities historically coincided with those of Mauna Loa, Kīlauea was once thought to be a satellite of its much larger neighbor.
 Structurally, Kīlauea has a large, fairly recently formed caldera at its summit and two active rift zones, one extending 125 km east and the other 35 km west, as an active fault of unknown depth moving vertically an average of 2 to per year.
Wao Kele O Puna (Wao Kele) is Hawaiʻ i's largest remaining lowland wet forest, about 15 mi south of the city of Hilo, along the East Rift Zone of Kīlauea volcano on the Island of Hawaiʻ i.
 The name means the "upland rainforest of Puna".
 Puna is one of 9 districts on the island.
 Lava from Kīlauea continues to flow onto forest land.
Vog is a form of air pollution that results when sulfur dioxide and other gases and particles emitted by an erupting volcano react with oxygen and moisture in the presence of sunlight.
 The word is a portmanteau of the words "volcanic", "smog", and "fog".
 The term is in common use in the Hawaiian islands, where the Kīlauea volcano, on the Island of Hawaiʻ i (aka "The Big Island"), has been erupting continuously since January 3, 1983.
 Based on June 2008 measurements, Kīlauea emits 2,000–4,000 tons of sulfur dioxide (SO) every day.

Question: What is the name of the volcanic cone in the eastern rift zone of the Kīlauea volcano of the Hawaiian Islands located in the middle of the As-Safa region?
Answer: Puʻu ʻŌʻō
