Reventador volcano, Ecuador: news & activity updates

Reventador volcano (Ecuador) activity update: lava flow on upper southern flank, numerous small to moderate explosions

Effusive and explosive activity at the surface as well as seismicity have continued to increase. A lava flow is traveling from the summit crater on the southern side towards the SE flank and there are numerous small explosions which create ash plumes of up to about 1 km height.
In its latest special report, IGPEN summarizes the evolution since 12 July as follows:
- 12 July: so-called drumbeats seismic signal, typical for magma ascent, followed by signals of rockfalls - this is likely the start of the lava flow.
- 13 July: an explosion and few long period (LP) tremors (typical for fluid movements)
- 14 July: low activity
- 15 July: more explosions and LP quakes as well as a strong pulse of tremor (continuous vibration)
- 16 July: numerous LP quakes and volcanic tremor, few explosions
- 17 July: starting at 10:30 (local time), a series of small and moderate explosions starts, accompanied by LP quakes.
- 18 July: LP quakes, tremor and explosions.

The IG reported that in the last few days, increased seismic activity indicative of increased eruptions has been noticed at the volcano. Seismic data also indicated the presence of a lava flow travelling down the SW slope of Reventador's intracaldera cone. [meer...]

An increase in seismic activity has occurred today. A steam plume can be seen rising above the volcano and a hot spot at the summit continues to be visible on MODIS satellite data, suggesting continuing lava extrusion. [meer...]
MODIS hot spot data (past 2 days) for Reventador volcano (ModVolc, Univ. Hawaii)
Monday, Jul 01, 2013
IGPEN characterizes the activity as moderate with seismic activity mainly related to internal fluid movements as well weak pulses of tremor and explosion signals. The volcano is hidden in clouds most of the time, but a thermal anomaly has become visible at the summit again on recent MODIS satellite data, possibly related to a recent small effusion of lava there.

Weak eruptive activity continues with occasional steam and ash emissions during small explosions that create plumes reaching about 1 km. [meer...]
Saturday, May 25, 2013
No significant changes have occurred recently. The volcano remains active at moderate levels and produces a steam plume 800-1000 m high and occasional small explosions. [meer...]
