There were more ash explosions spotted at Ebeko in Kamchatka, producing ~1.8 km (5,900 foot) ash columns. This activity prompted KVERT to raise the Alert Status to Yellow. This goes along with news from a pile of other Kamchatka/Kuril Island volcanoes: Gorely, Tiatia, Karymsky, Kliuchevskoi and Shiveluch.
More activity at Arenal in Costa Rica – its almost always busy – including strombolian activity shaking windows up to 4 km from the vent.
Over in Hawai`i, activity at Kilauea continues, with the lava lake in the summit Halema`uma`u Crater and the growth of several rootless shield vents on the East Rift Zone.
Finally, light ash fall was observed around Soufriere Hills on Montserrat for the first time since February of this year – coincident with some seismicity underneath the volcano. Alert Status remains at 3 for the volcano.
