Chile’s Reclus volcano stirred from sleep by earthquakes, after 104 years

August 31, 2012  CHILE - Some unrest is going on at Reclus volcano in southern Chile, located between Aguilera and Monte Burney in Patagonia, the Eruptions Blog writes: “Over the summer, earthquakes began to be felt in towns in the region of the volcano and a potential for new activity from the Reclus has prompted geologists to visit the volcano later this spring (southern hemisphere). Interestingly, one article mentions that an over-flight of the volcano in 2008 spotted cracks on the glaciers that cover the volcano along with traces of ash. However, the direct connection between the seismicity in Patagonia and Reclus is still tenuous, so further observations of the remote volcano will need to be done.” Reclus has had at least 4 historical eruptions around, 1908, 1879, and in 1869. Although these were small, the volcano has produced larger explosive eruptions in the past and should be closely monitored. – Volcano Discovery

Awakening? Earthquake swarm reported at San Pedro-Pellado volcano- eruption would be first in recorded history

June 8, 2012 – CHILE – Apparently, the SERNAGEOMIN has been monitoring an earthquake swarm at Chile’s Tatara-San Pedro (also known as San Pedro-Pellado), possibly numbering in the hundreds of small earthquakes over the last few days. The reports are a little scant and the information coming from different parts of the Chilean government are contradictory: the regional governor of the area was quoted as saying that “it is of volcanic earthquakes, so we are on alert” while the regional director from ONEMI said “at first thought that we were facing a volcanic earthquakes, but known reports of the analysis has led to the conclusion that we were facing tectonic type earthquakes.” The article in La Tercera also mentions that the volcano hasn’t erupted in “decades” while the Global Volcanism Program’s entry for San Pedro says that the last eruption is “unknown,” likely in the Holocene (last 10,000 years). So, there seems to be lots of confusion (not to mention La Tercera calling the volcano “Catinao”). If this is renewed activity at the volcano, it is potentially the first in recorded history. –Wired
