About Kilauea volcano
- More than 140 earthquakes were recorded as of 4.30 a.m. The largest was magnitude 3.3. Most were less than magnitude 1.
- At the same time as the swarm, scientists recorded changes to the ground surface of the volcano.
- That may indicate magma was moving beneath the southern part of Kilauea’s caldera, the observatory said.
- There was no evidence of lava at the surface.
- The observatory changed its volcano alert level to ‘watch’ from ‘advisory’, meaning Kilauea is showing heightened or escalating unrest with more potential for an eruption.
- Kilauea volcano is one of the world’s most active volcanoes, having erupted 34 times since 1952. Kilauea is about 200 miles south of Honolulu, on the Big Island of Hawaii.
