Kilauea (Hawai’i): (21 Sep) Following the inflation cycle that began 2 days ago (and might be now turning into deflation), the lava lake in the Halema’uma’u summit crater has risen again into clear view from the HVO observatory. This morning, its surface was only 12 m (39 ft) below the rim.
An explosion of the lava lake was observed yesterday around 21:15 local time – probably triggered by a larger rockfall from the unstable crater walls, a fountain of incandescent material rose from the NE end of the lake to about the outer rim near the old overlook area, generating a plume of steam and ash that rose several hundred meters and quickly dissipated SW.
The two sea entries at Kamokuna remain active and well alimented; additionally, active pahoehoe breakouts are present about 2 km (1.2 mi) inland from the coast and higher up on the pali.
Turrialba (Costa Rica): After a day of relative calm, a new pulse of ash emissions occurred from the volcano this morning.
The current phase of activity at the volcano began around 13 Sep with renewed, but sporadic and weak ash emissions, but intensified drastically on 19 Sep reaching a new peak of activity (so far). Between 02:53 and 15:30 local time, the volcano produced several phases of near-continuous explosive activity with strong ash emissions, generating several ash plumes that rose more than 1000 m, drifted west into the Central Valley, causing moderate to heavy ash falls and forcing a temporary closure of the capital’s Juan Santamaria International Airport.
Some of the explosions were strong enough that part of the dense eruption columns collapsed into small pyroclastic flows that spread onto the crater floor. There are no reports of damage or injuries.
