The alert level was raised a notch last week, as volcanologists from SERNAGEOMIN started to record a significant increase in seismicity associated with a slight inflation of the volcanic edifice,- typical signs of magma intrusion at depth under the volcano.
Wed, 19 Aug 2015, 06:00According to the civil protection agency, ONEMI, on 18 August OVDAS-SERNAGEOMIN reported that seismicity at Calbuco fluctuated at low levels and continued to decline, and only water vapor emissions rose from the vents. The Alert Level was lowered to Green (the lowest level on a four-color scale). ONEMI maintained an elevated Alert Level of Yellow (mid-level on a 3-color scale) for the Llanquihue and Puerto Octay provinces, and an Alert Level Green for Puerto Montt and Puerto Varas.

OVDAS-SERNAGEOMIN reported that during 20-26 May activity at Calbuco fluctuated at low levels and continued to decline. Inclement weather prevented observations of the summit area on most days; white plumes were observed rising 300-400 m and drifting SE during 24-26 May, and incandescence at the crater was observed at night during 25-26 May. According to ONEMI, the number of evacuees within the 20-km evacuation zone remained at 6,685 on 26 May.

Wed, 27 May 2015, 06:00On 27 May OVDAS-SERNAGEOMIN reported that seismicity at Calbuco fluctuated at low levels and continued to decline. According to ONEMI, the 10-km evacuation zone remained in effect, with controlled access to some communities allowed for part of the day; about 500 people remained displaced. On 28 May OVDAS-SERNAGEOMIN lowered the Alert Level to Yellow (the second lowest level on a four-color scale).

Activity has decreased gradually during the past weeks. Only degassing has been occurring at the summit vents lately and tremor levels show a decline.

OVDAS-SERNAGEOMIN reported that during 13-19 May activity at Calbuco fluctuated at low levels and continued to decline. Inclement weather prevented daily observations of the summit area, although incandescence at the crater was observed during 17-18 May. According to ONEMI, the number of evacuees within the 20-km evacuation zone remained at 6,685 on 18 May.

Wed, 6 May 2015, 06:00OVDAS-SERNAGEOMIN reported that on 6 May activity at Calbuco fluctuated; a sudden increase of tremor that began at 1304 and lasted two hours was accompanied by increased gas-and-ash emissions. During 7-11 May the gas-and-ash emissions were steady and low (less than 1 km), and drifted E, SE, and S; inclement weather prevented observations during 8-10 and 12 May. Moderate levels of tremor were detected through 9 May, and then decreased to low levels through 12 May.

Ash column erupted from Calbuco today
A strong explosive eruption occurred today (12:10 on 30 April, local time) at the volcano, producing an ash column that rose several kilometers above the summit crater.

Wed, 29 Apr 2015, 06:00OVDAS-SERNAGEOMIN reported that on 29 April a weak ash plume rose as high as 1.5 km above Calbuco and seismicity remained stable. An event that began at 1308 on 30 April produced an ash plume that rose 3-5 km and drifted SE. A small lahar in the Blanco River may have been caused by a pyroclastic flow.

Glow from Calbuco this morning
Mild to moderate emissions of ash and incandescent material (probably as strombolian explosions) continue at the summit vent(s). A small ash plume rises approx. 1 km and is currently drifting east.

Ash emission from Calbuco this evening
Starting from 23:30 local time last night (23 April), activity at the volcano has again increased. The volcano started to produce more or less continuous small to moderate ash emissions, that have been reaching up to 2 km height and drifted mainly northeast.

Fri, 24 Apr 2015, 07:50The volcano has so far stayed calm, but the alert level remains at red because another explosion could occur. A major problem in this situation seems to be that eruptions such as the recent one are likely to remain something impossible to predict - at least in some cases.

The 21 y-o mountaineer who was missing and feared victim of the eruption has survived and has been rescued, fortunately. Together with a small group of friends, he was on excursion on the mountain when the eruption occurred last night.

Wed, 22 Apr 2015, 06:00OVDAS-SERNAGEOMIN reported that an eruption from Calbuco began at 1804 on 22 April, prompting the Alert Level to be raised to Red (the highest level on a four-color scale) and causing a 20-km exclusion zone to be declared. The eruption was preceded by an hour-long period of volcano-tectonic events followed by long-period events; no increases in seismicity had been noted since 2009 when real-time seismic monitoring started. After a large seismic event detected at 1735, a 90 minute eruption generated a sub-Plinian, gray ash plume that rose 15 km above the main crater and drifted mainly ENE, although fine ash drifted N and NW.
