Cayambe volcano, Ecuador: news & activity updates

Cayambe volcano (Ecuador) - Smithsonian / USGS Weekly Volcanic Activity Report for 14 December-20 December 2016 (Continuing Activity)

IG reported that a seismic swarm detected at Cayambe on 5 June was characterized by an increase in the number of volcano-tectonic events. The swarm occurred near an active fault system, NE of the volcano. The seismic activity progressively declined to baseline levels during August. Read all

Cayambe volcano (Ecuador): increased earthquakes show volcano has become restless

The volcano has become restless. Scientists from Ecuador's Institute of Geophysics (IGEPN) recorded an increased number of earthquakes under the volcano a new report shows. The increased seismicity could be (but not must be) a precursor of renewed activity in the medium-term future (weeks, months?). Read all

Cayambe volcano (Ecuador) - Smithsonian / USGS Weekly Volcanic Activity Report for 28 September-4 October 2005 (Continuing Activity)

A cluster of earthquakes that had been recorded at Cayambe since 16 September, with about 300 small earthquakes occurring during 16-18 September, decreased in number significantly after 19 September. During 19-25 September, an average of 5.3 earthquakes occurred daily. Read all

Cayambe volcano (Ecuador) - Smithsonian / USGS Weekly Volcanic Activity Report for 14 September-20 September 2005 (Continuing Activity)

During 16-18 September, a cluster of 330 small earthquakes occurred at Cayambe. The earthquakes reached a maximum magnitude of 3.6. They occurred on the volcano's SW flank, where previous clusters had been located. Read all

Cayambe volcano (Ecuador) - Smithsonian / USGS Weekly Volcanic Activity Report for 18 February-24 February 2004 (Continuing Activity)

On 29 January a swarm of ~148 small volcano-tectonic earthquakes occurred at Cayambe. By 1 February seismicity had decreased, reaching "normal" base levels. IG reported that the swarm may have represented an increase in the internal pressure of the volcano due to the arrival of fluid, possibly magma. Read all

Cayambe volcano (Ecuador) - Smithsonian / USGS Weekly Volcanic Activity Report for 12 November-18 November 2003 (Continuing Activity)

During 3-9 November, about nine earthquakes occurred per day at Cayambe, near the daily average since August 2003 and about twice the daily average of 4 per day before that. Seismicity also included small clusters of tectonic earthquakes with magnitudes less than 3. There were reports of a strong scent of sulfur in the sector of Picos Jarrína at an elevation of ~5,460 m.
