Ubinas is Peru's most active volcano. A small, 1.4-km-wide caldera cuts the top of the volcano. The steep-walled, 150-m-deep summit caldera contains an ash cone with a 500-m-wide and 200 m deep crater Debris-avalanche deposits from the collapse of the SE flank of Ubinas about 3700 years ago extend 10 km from the volcano. Widespread plinian pumice-fall deposits from Ubinas include one of Holocene age about 1000 years ago. Holocene lava flows are visible on the volcano's flanks, but historical activity, documented since the 16th century, has consisted of intermittent minor-to-moderate explosive eruptions.

2013 Sep 1: People in Peru are being relocated from villages that are being affected by dangerous ash from a volcano eruption. Authorities are distributing masks and have given themselves a 60-day period to relocate villagers from areas where ash is damaging crops and polluting water sources. The explosions have sent a plume of smoke rising to 2500 meters above the crater, according to volcanologists at the Geophysical Institute of Peru. The first explosion on the night of September 1 was strong and followed by a series of lesser blasts, seismologist Victor Aguilar of the Geophysical Institute of the University of San Agustin de Arequipa told AFP. (reference #10739) According to a news source, IGP reported that a seventh phreatic explosion from Ubinas occurred just after 1800 on 4 September; six explosions were recorded between 1 and 3 September. The explosion caused alarmed residents of Querapi, 4 km S, to temporarily leave their homes and congregate in the town square. (reference #2432) Cited references #2432 Venzke, E., R.W. Wunderman, L.

Remark:

Our list of volcanic eruptions closely follows the database of eruptions of the Smithsonian's Global Volcanism Project (GVP), the internationally most recognized data source for volcanic eruptions, but also includes significant eruptive episodes or related volcano events. "Volcanic eruptions" are usually to be understood as sequences of individual eruptive episodes that can follow each other, or even overlap (if several vents are involved), and can last many years, decades or even longer. For example, the current activity of Stromboli volcano is understood as a single eruption that has been ongoing since 1934.

Ubinas Volcano FAQ

+When was the last eruption of Ubinas volcano?

The last confirmed eruption of Ubinas occurred in 2024.

+How often does Ubinas volcano erupt?

Since 1550 AD, Ubinas volcano has had at least 22 historically documented eruptions. This means that it erupts on average every 21.6 years.
Many eruptions of Ubinas have lasted more than one year. In total, the volcano has been in eruption during 28 out of 475 years until now. In other words, Ubinas has been active at least one in 17 years on average. Note that this value is likely an underestimate, because the known history of eruptions from Ubinas is likely incomplete, especially further back in time.

+How active is Ubinas volcano at present?

Ubinas volcano is relatively active: Since 1900, it has had 18 eruptions, and been active during 18 years out of 126 as of now. This means, Ubinas has been in eruption one in 7 years on average. The last eruption was in 2024 and ended 11 months ago.

+When was the largest eruption of Ubinas volcano?

The largest eruption known from the younger geological history of Ubinas volcano occurred around 1082 AD. It ranks as a "vulcanian" eruption with a magnitude 3 on the VEI (Volcanic Explosivity Index) scale.
