Volcanic activity worldwide 12 Apr 2016: Pavlof Volcano, Sakurajima, Telica

Eruption from Sakurajima this afternoon

Source: Volcano Discovery

Sakurajima (Kyushu, Japan): The volcano continues to have relatively strong vulcanian-type explosions at varying rates between 0-3 or more per day, and again mostly from the Showa crater (on the upper eastern flank)
An explosion this afternoon generated an ash column that rose to 15,000 ft (4.5 km) altitude.

Pavlof (Alaska Peninsula, USA): The most recent eruption (or eruptive phase) of the volcano that had begun on 27 March lasted only a few days; after no more activity had been observed for a week, AVO lowered the alert level back to Yellow on 6 April.
The possibility remains that activity resumes with little warning: “Pauses in vigorous eruptive activity of days to weeks are common during eruptive episodes of Pavlof Volcano. A return to robust eruptive activity remains possible and could occur with little or no warning.” (AVO)
 
“Over the past week, seismicity at the volcano has remained at low levels and shows no indication of activity associated with ash emissions or lava effusion.
Satellite observations show no evidence for continuing eruptive activity. Thermal signals at the summit are occasionally visible, but are likely being generated by the cooling of previously erupted lava and debris.

Telica (Nicaragua): The activity of the volcano remains elevated, with little changes over the past days. Bright incandescence inside the crater and mild to moderate degassing, sometimes with light ash content, are visible at the surface.
Internal micro-seismic activity continues to be at high levels according to INETER’s latest report. The risk of sudden explosions from the crater remains considerable and people are advised not to approach the crater.
