Reventador, Ecuador

The IG reported that seismicity from Reventador increased during 25-26 March. On 26 March, the seismic network detected an earthquake swarm consisting of long-period and hybrid events, interspersed with bands of harmonic tremor. Observers reported steam emissions with low ash content.

The IG reported that SOTE (Sistema de Oleoducto Transecuatoriano) personnel and residents near Reventador observed incandescence in the crater on 7 November. The reports were confirmed by the presence of thermal anomalies in satellite imagery. The next day, seismicity increased and a steam-and-ash plume rose to an approximate altitude of 5.6 km (18,400 ft) a.s.l. [...]

Reventador, Ecuador

The IG reported that the number of earthquakes per day from Reventador increased during July and were the greatest on 24 and 25 July. At 1500 on 27 July, continuous seismic tremor was registered and was followed by observations of incandescence around the crater. Thermal anomalies were also identified on satellite imagery. At 1900 explosions [...]
