The recordings of seismic tremor signal type remains on the instruments, and emissions of steam and gas with low concentrations of ash continue. Emissions have varied in direction, they are being directed to the Southeast and West. Several teams of experts from the Institute of Geophysics conduct studies on the gravity of the volcano and the collection of samples of ash.
Technical annex and observations:
Seismicity: Since 0600 (TL) and until 18:00 (TL), were registred : One long period type event (LP), 31 episodes of tremor emission (TE) , 5 events volcano – tectonic type (VT ) and 2 earthquakes VLP type .
Observations, emissions and ash: During the morning hours, the volcano was clear, gas and steam emissions were observed with low concentrations of ash. The emissions reached a height of 2 km above the crater, heading southwest and west of the volcano. In the afternoon, emissions have persisted and reached a height of 1.3 km above the crater. So far, there is no ash falls reports.
Gas: From 7:00 to 5:00 p.m. yesterday, the SO2 concentration was 8,000 t / d.
Rain: No rain was recorded in the volcano area.
