Volcanic activity worldwide 29 Apr 2015: Kilauea volcano

Wednesday Apr 29, 2015 21:00 PM |

Overflow of Kilauea's summit lava lake early this morning
Overflow of Kilauea's summit lava lake early this morning
Kilauea (Hawai'i): For the first time since its appearance in 2008, the lava lake has spilled over into the floor of Halema'uma'u crater.
HVO reported continued although weakening inflation, sign that magma continues to rise into the caldera, which might result in further increase of the lake. "The lava lake level has been at or near the rim of the Overlook crater over the past day. At 9:40 pm last night, a very small, brief overflow occurred onto the floor of Halemaʻumaʻu Crater. A larger overflow occurred at 2am this morning, sending lava a short distance onto the floor of Halemaʻumaʻu Crater, and another overflow is occurring this morning around 8am. Seismicity is elevated beneath Kilauea's summit and upper East and Southwest Rift Zones."

An explosion from the lake was triggered yesterday morning 10:20 am local time when a rockfall from the walls of the crater occurred. Liquid lava spatter was thrown to the area around the closed Halemaʻumaʻu visitor overlook.
