White Island volcano (New Zealand): Volcanic Alert Level lowered to Level 1; seismic unrest continues
Observations and monitoring data over the last few months indicate that Whakaari/White Island has been progressing on a gradual trend back to lower levels of unrest that are typical of the long-term behaviour of this volcano. The data sets considered in interpretation include discharge rate of sulphur dioxide (SO2) and carbon dioxide (CO2) gases, seismic activity, and the temperature of the…
Nishino-shima volcano (Volcano Islands, Japan): effusive-explosive eruption continues
The Japan Coast Guard (JCG) did a flight observations yesterday. An explosions at the volcano generated a dense gray and black ash plumes, which rose approx. 6,561 ft (2,000 m) above the summit. Emissions of ash content is extending about 130 km to the east of the volcano. Blocks were ejected as far as 2,5 km away from the crater. Lava effusions continue to be active on the northeastern slopes…
Sangay volcano (Ecuador): increasing activity
According to IGEPN, the activity at the volcano has been increasing during the past few days associated with increasingly larger ash plumes as can be seen rising from the crater to an altitude of 23,000 ft (7,000 m). An ash plumes is extending about 600 km to the west of the volcano. It produced pyroclastic flows that traveled over the southern slopes and accumulate a material on the flanks of…
