Introduction
Sirung volcano is located at the NE end of a 14-km-long line of volcanic centers that form a peninsula at the southern end of Pantar Island. The low, 862-m-high volcano is truncated by a 2-km-wide caldera whose floor often contains one or more small lakes. Much of the volcano is constructed of basaltic lava flows, and the Gunung Sirung lava dome forms the high point on the caldera's western rim. A number of phreatic eruptions have occurred from vents within the caldera during the 20th century. Forested Gunung Topaki, the 1390-m high point of the volcanic chain, lies at the SW end and contains a symmetrical summit crater.---

Eruptions du volcan Sirung
Strong fumaroles and boiling springs are found in Sirung's large crater. The crater contains often a highly acid (pH = 0.75), warm (40 deg C), grey-coloured crater lake where volcanic gasses escape in bubbles. The gasses are unusually rich in chlorine. The lake is similar to Kawah lien crater lake in East Java. ...plus d'info
A second area of hot springs is found on the beach of Beangabang Bay east of Sirung's crater. Water from these springs mixes with seawater.
Eruptions of "smoke and dust" were reported by press around 13 May 2004, but according to the Indonesian Volcanological Survey, these reports were false.
A volcanologist from the Indonesian Volcanological Survey visited the volcano on 12 December, following an earthquake of M6.5 on 26 November. Fumaroles and the crater lake were normal and showed no evidence of increased activity. The only notable change in the crater was a fresh landslide scar that perhaps had resulted from the earthquake.
Sirung volcano erupted on 14-15 June 1934. Detonations were heard in Ilakalau village and the following morning the crater rim was observed to be covered by white fresh ash deposits. On 16 June lapilli fell in Ilakalau village. On 17 June dense ash clouds were erupted 5-10 minutes. On 26 June, 30 m high lava fountains or strombolian activity were observed at the crater.
Sirung Volcano FAQ
+When was the last eruption of Sirung volcano?
The last confirmed eruption of Sirung occurred in 2021.
+How often does Sirung volcano erupt?
There are no known historic eruptions, but evidence from geologic records shows that it has had at least 11 eruptions over the past 10,000 years. This number is likely much higher because many past eruptions might not have left evidence recognizeable today and/or the volcano might not have been studied in too much detail. Using the available data, a very conservative estimate is that Sirung volcano erupts every 909 years.
+How active is Sirung volcano at present?
Sirung volcano is infrequently active: Since 1900, it has had 10 eruptions, and been active during 10 years out of 126 as of now. This means, Sirung has been in eruption one in 12.6 years on average. The last eruption was in 2021 and ended 4 years ago.
+When was the largest eruption of Sirung volcano?
The largest eruption of Sirung volcano in historic times occurred in 2012. It ranks as a strombolian to vulcanian eruption with a magnitude 2 on the VEI (Volcanic Explosivity Index) scale.
