Earthquake activity around the Big Island of Hawaii volcano has also increased in recent weeks, with a peak of one magnitude 3.8 quake and 42 smaller earthquakes on the morning of Feb. 10. Geologists this morning reported 29 earthquakes had occurred within Kilauea volcano in the last 24 hours.
HVO geologists posted audio yesterday of lava lake activity within the Halemaumau vent from Monday afternoon. The continuous noise reminiscent of waves crashing is churning lava as gases are released from the lake surface. The sharp popping sounds are falling rocks from the vent wall hitting the lava lake surface.
A few miles southeast of Halemaumau crater, lava within Kilauea volcano’s Puu Oo crater continues to erupt sporadically from three vents.

Access to Puu Oo is off limits to hikers. But activity at Halemaumau crater is visible to Hawaii Volcanoes National Park visitors from the Hawaiian Volcano Observatory’s Thomas A. Jaggar Museum overlook, which is open 24 hours daily. Daily updates on Kilauea volcano activity are available at the Hawaiian Volcano Observatory website.
