MODIS hot spot data (past 2 days) for Reventador volcano (ModVolc, Univ. Hawaii)
Activity has remained moderate with occasional explosions and possibly the emplacement of a hot avalanche or lava flow on the eastern flank, where a new hot spot on the latest MODIS satellite data can be seen, in addition to the summit where a lava dome is active.
Activity remains moderate with frequent small explosions detected on seismic signals and strong degassing producing a plume that was observed yesterday rising 800 m.

Activity has decreased lately, with only occasional small explosions and weak steaming observed. The MODIS data show no longer a hot spot, suggesting that lava effusion has more or less stopped.

A MODIS hot spot at the summit and fluctuating moderate levels of seismicity suggest that slow lava extrusion and occasional explosions continue. ...more

Current seismic signal from Reventador (CONE station, IG)
A slowly decreasing trend of activity is visible, but there are still occasional small explosions and strong degassing. Volcanic earthquakes and tremor fluctuates between low to moderate levels.
IG reports surface and internal (seismic) activity at stable, moderate levels. A steam plume rising 700 m above the crater, where a lava dome continues to grow, was observed.
Current seismic signal from Reventador (CONE station, IG)
A steam column was seen rising 1 km above the crater yesterday. Seismic activity remains alternating between periods of calm and bursts of tremor / explosion signals.
Current seismic signal from Reventador (CONE station, IG)
Activity has remained stable at fluctuating moderate levels, but can rarely be observed directly due to near-constant cloud cover. Explosions and volcanic tremor, sometimes strong as earlier today, are visible on seismic recordings.
Current seismic signal from Reventador (CONE station, IG)
Strong steaming was observed during a window of clear weather. The seismic activity remains moderately high, with numerous moderate long period earthquakes, harmonic tremor pulses and signs of moderate explosions.

A thermal anomaly at the summit and continuing explosion earthquakes mixed with low-level volcanic tremor suggest that lava extrusion at the summit crater has resumed (or rather continues more vigorously) these days.

Activity fluctuates between relatively calm phases and strong ash emissions. In the evening of 13 March, a steam and ash column was seen rising 3 km above the crater.

The volcano's activity is considered moderate. In the afternoon of 12 March, IG staff and observers noted incandescent material rolling down the slopes of the volcano (mainly on the southern side). A column of steam and ash occasionally reaches 1km height, but most of the time, emissions have been weaker than that.

Mild activity continues, but is rarely visible. At night, glow from the crater can sometimes be seen. ...more
IG reports sporadic weak explosions, and continued elevated seismic activity with numerous long-period events, explosion signals and tremor pulses. [less]
Current seismic signal from Reventador (CONE station, IG)
Magma continues to arrive in the summit crater, evidenced by glow observed during the night. The seismic station experiences transmission problems, but still shows many long-period earthquakes as sign of internal activity at the volcano.
Current seismic signal from Reventador (CONE station, IG)
The eruption at the volcano continues at fluctuating levels, which is reflected by the seismic signal. Yesterday, an ash column rose 2 km above the crater and drifted to the west. No reports of ash fall were received by IG.

Last night's signal (CONE station)
After a phase of more intense activity yesterday, the volcano has been quieter today. ...more
Tremor has decreased, but there are still many volcanic earthquakes and explosion signals. A MODIS hotspot indicates that some lava extrusion probably continues at the summit. [less]

Yesterday evening's seismic signal from Reventador (CONE station, IG)
Seismic activity with continuous strong tremor continues, but cloud cover prevented direct observations of the ongoing activity (likely lava dome grown with lava flow extrusion as well as ash emissions).

The activity of the volcano remains strong. The new summit lava dome continues to grow and produce explosions and feed active lava flows on the upper flank. ...more
During the afternoon of 31 Jan, an strong emission column of steam and moderate ash content could be observed rising 3.5 km above the crater. Seismic activity remains at a high level, with a daily average of 20 earthquakes related to fluid pressurization and movement inside the volcano, and a daily average of 29 explosions since 22 January.
