MODIS hot spot data (past 2 days) for Tolbachik volcano (ModVolc, Univ. Hawaii)
Seismic recording this morning at Nevado del Ruiz (OLL station, INGEOMINAS)
Kizimen (Kamchatka): Activity continues with little changes. Video data showed that the lava dome is still active and produces incandescence and hot avalanches on the western and eastern flanks. Strong and moderate gas-steam activity accompany this process. Satellite data showed a thermal anomaly over the volcano. (KVERT)
Tolbachik (Kamchatka): Although tremor continues to decrease very slowly, KVERT reports that fluid lava is still being erupted from the vent on the southern fissure. MODIS satellite data still show a large hot spot, confirming that the eruption might be longer lasting than thought.
Paluweh (off Flores Island, Indonesia): The lava dome continues to be active and produce explosions and small pyroclastic flows from time to time, generating ash plumes rising to 7-10,000 ft such as today.
Popocatépetl (Central Mexico): Activity at the volcano continues to increase. A relatively long phase of strong volcanic tremor today and high levels of SO2 output suggests that the rise of magma is accelerating. A continuous plume of steam and some ash was observed last night reaching 1 km high, in addition to intermittent explosions. Lava glow at night is now strong.
Nevado del Ruiz (Colombia): A small seismic swarm, likely caused by the rise of another new small batch of magma, occurred this morning at the volcano. The hyopcenters were located 4 km SW of the Arenas crater at depths between 4-6 km, INGEOMINAS reported.
