SERNAGEOMIN reported minor increases in surficial activity at Láscar. Nighttime incandescence from the crater began to be visible at least since 11 January. A total of 14 thermal anomalies were identified in satellite data during 13-28 January; the intensity of the anomalies increased on 17 January and peaked on 22 January. Read allWed, 4 Apr 2018, 06:00
OVDAS-SERNAGEOMIN reported that, although seismicity at Láscar during March was low, characteristics of the signals were similar to patterns observed prior to previous minor phreatic explosions, particularly before events in 2013 and 2015. The Alert Level was raised to Yellow (second highest level on a four-color scale); SERNAGEOMIN recommended no entry into a restricted area within 5 km of the crater. ONEMI declared an Alert Level Yellow (the middle level on a three-color scale) for San Pedro de Atacama. Read allShow more

Ash plume from Lascar yesterday
Wed, 28 Oct 2015, 06:00
OVDAS-SERNAGEOMIN reported that at 0932 on 30 October the webcam recorded an ash plume rising 2.5 km above Láscar and drifting NE. A low-to-moderate-level seismic signal accompanied the emission. The Alert Level was raised to Yellow (the second lowest level on a four-color scale). Read allSun, 14 Apr 2013, 08:58
The incandescence observed at the crater due to hot gas emissions has decreased during 12-13 April and was no longer visible during last night.Thu, 11 Apr 2013, 12:51
Chilean volcanologists were able to make make a helicopter overfly the day before yesterday and could not find evidence of recent lava in the summit crater. However, as the likely source of the recently observed incandescence, very hot gas emissions were observed. Read allThu, 4 Apr 2013, 08:36
A new eruption occurred yesterday at the volcano. SERNAGEOMIN reported that at 09:20 (local time) on 3 March degassing became more intense at the volcano. The plumes were sometimes grey colored, suggesting slight ash content. Incandescence was visible at night. Despite this activity, seismicity remains normal. The (official) Alert Level remains at GREEN.Show more

OVDAS-SERNAGEOMIN reported that during March a web camera monitoring Láscar recorded white gas plumes rising 600 m above the crater. At night during 2-4 April incandescence from the crater was observed. On 3 April increased emissions from the crater fluctuated from white to gray, indicating possible ash.

Lascar volcano in northern Chile was placed on heightened alert status YELLOW, after SERNAGEOMIN detected a swarm of over 300 small earthquakes between 4 and 5 January.Wed, 4 Jan 2012, 06:00
OVDAS-SERNAGEOMIN reported increased seismicity at Láscar on 5 January and raised the Alert Level from Green to Yellow. On 8 January ONEMI authorities warned residents about the new Alert Level status and restricted residents from going within a 20-km radius of the volcano. Read allWed, 18 Jul 2007, 06:00

Several small phreatic explosions occurred at Lascar during May, July, and August. The explosions were separated in time by up to several weeks. The last observed explosion, lasting for about five minutes on 14 August, produced a plume that reached a height of 450 m above the crater (19,800 ft a.s.l.) and dispersed ESE.

Several phreatic explosions occurred at Lascar daily during 18-21 April. The explosions produced plumes of gas and small amounts of ash, with the highest rising plumes reaching 3 km above the volcano (or 28,200 ft a.s.l.) on the 18th and the 21st. Ash was deposited on the volcano's flanks as far as 3 km from the summit. Read allWed, 12 Apr 2006, 06:00
