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.

After a phase of more intense activity yesterday, the volcano has been quieter today.
Current seismic signal from Reventador (CONE station, IG)
In the morning and afternoon yesterday, IG could observe a moderately ash-charged emission column rising about 2 km above the crater.
IG reported that seismicity at Reventador was high during 6-7 February and moderate during 8-12 February; explosions were detected daily. An ash plume rose 3 km and drifted S on 7 February, and ashfall was reported in areas near the volcano on 9 February. Cloud cover often prevented observations.
Current seismic signal from Reventador (CONE station, IG)
Activity remains high with strong constant tremor visible, likely accompanying lava effusion from the rarely visible summit.

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.

Seismic activity remains high, but seems to be slowly decreasing. A steam plume and weak glow from the summit could be observed yesterday.

During an overflight of Reventador on 29 January scientists observed an explosion and a steam-and-ash plume that rose 1.5 km above the lava dome. Since November the dome had significantly grown to at least 100 m higher than the E rim, and about 20 lava flows had traveled down the N, SE, and S flanks.

The lava flow from Reventador on 22 Jan 13
Activity remains at high levels. IG reports strong tremor and explosion signals. The current webcam image shows only a steam plume rising from the summit, but it is unclear if the lava flow seen on 22 Jan is still active.

Current seismic signal from Reventador (CONE station, IG)
Activity continues, but likely has becoming more intermittent judging from the seismic signal. Visual observations are most of the time impossible.

Current seismic signal from Reventador (CONE station, IG)
IG reported lava flows descending from the summit area and continuous emissions creating a 2 km tall plume yesterday (24 Jan). Several hot spots are visible on MODIS images.

Current seismic signal from Reventador (CONE station, IG)
The volcano has now entered a full-scale eruption. Lava flows descending on the flanks and glow at the summit were observed. A tall steam and ash plume rises 1.5 km above the volcano and drifts west. Additionally explosions have been reported which were heard in the sector of Reventador.

Seismic signal Reventador this morning (CONE station, IG)
From 09:00 (local time) 21 Jan, a strong increase in seismic activity occurred, dominated by low frequency tremor, possibly associated with fluid pressurization and movements of magma inside the conduit of the volcano.

IG reported that in the morning of 22 January tremor at Reventador increased significantly and signals indicating rockfalls were detected. Explosions were heard during the afternoon and evening that same day. After an explosion in the crater a gas-and-steam plume was observed rising 1.5 km above the crater.

Current seismic signal from Reventador (CONE station, IG)
Strong seismic activity with many volcanic quakes and tremor accompanies strong degassing and sometimes small explosions from the growing lava dome. The activity seems currently to be increasing.

Strong seismic activity including some explosion signals and a hot spot visible on satellite images suggest that the lava dome in the summit crater continues to be active.

IG reported that during 16-21 January seismicity at Reventador was moderate; cloud cover prevented visual observations. Incandescence in the crater was observed at night during 21-22 January. Starting at 0900 on 22 January seismicity at Reventador increased and was characterized by constant low-frequency, high-energy tremor detected by seismic stations around the volcano.

Current seismic signal from CONE station (IG)
Seismic activity continues to show an increasing trend with numerous volcanic quakes, long-period events and some explosion signals. A 500 m stea plume could be observed.

Current seismic signal from CONE station (IG)
Seismic activity is at moderate levels with pulses of tremor suggesting ongoing emissions of gas and possibly ash. During times of clear weather, strong steaming could be observed.
