A new lava flow started to emerge from the summit vent.
The lava came out shortly after at 07:47 local time yesterday, by producing two lava lobes of which its fronts have reached length of 500 meters from the crater. Glowing lava blocks frequently detach from the lava flows and roll over the southern Mi-Isi and southeastern Basud gullies descending approx. 2 km distance from the summit.
A weak seismic activity accompanies the effusive eruption. Over the past 24 hours, 21 volcano-tectonic earthquakes have been detected.
Prior to the lava flow, instruments registered upper slopes to be inflated slightly.
According to the Volcanic Ash Advisory Center Tokyo (VAAC), an eruption occurred from the volcano at 03:09 local time tonight, generating an ash column that rose to estimated 5,5 km.
Sulfur dioxide (SO2) emissions reached to a 642 tonnes yesterday, a half amount of previous measurements on 10 June.
In order to mitigate the risk, people are forbidden to enter an area of 6 km distance from the summit crater due to impacts of rockfalls, pyroclastic falls and/or phreatic eruptions.
The alert level for the volcano remains at Level 3.
