Aso volcano (Kyushu, Japan): strong, dangerous explosion this morning with pyroclastic flows

Monday Sep 14, 2015 15:04 PM | BY: T

Eruption of Aso volcano this morning
Eruption of Aso volcano this morning
A powerful explosion occurred this morning from the Nakadake crater, producing a dense ash cloud that collapsed into several pyroclastic flows and rose approx. 2 km above the crater.
The eruption which occurred at 09:43 local time came with apparently little or no warning. It is not known whether it was a magmatic (involving fresh magma) or phreatic explosion (driven by overheated steam). During the past weeks, the volcano had been relatively calm, only showing occasional ash venting, strong degassing and weak glow visible at night from the main vent.
Video of the eruption:

Fortunately, the crater had been off-limits to visitors, as the volcano was still in alert level 2 and the eruption did not cause victims. Following the explosion, the alert level was raised to 3 on a scale of 1-5 and an exclusion zone was increased to 2.5 km radius.
30 people who were parked near the park buildings were evacuated.
