Scientists record swarm of earthquakes at Hawaii volcano

Geologists have recorded a swarm of earthquakes on Hawaii’s Kilauea volcano, though it is not erupting. The earthquakes began overnight and continued into the morning, the Hawaii Volcano Observatory reported.

As of 4:30 a.m., more than 140 earthquakes had been recorded. The largest had a magnitude of 3.3. Most of the quakes were less than 1.

Simultaneously with this swarm, scientists recorded changes on the surface of the volcano. This could indicate magma movement beneath the southern part of Kilauea’s caldera, the observatory said. There was no evidence of lava on the surface.

The observatory has changed the volcano warning level from advisory to observational, which means Kilauea is showing increased or escalating excitement with a greater likelihood of eruption.

Kilauea is one of the most active volcanoes in the world, having erupted 34 times since 1952.

In 2018, about 700 homes were destroyed when lava gushed through volcanic vents in a residential area in the final year of an eruption that lasted more than three decades.

Kilauea is about 200 miles south of Honolulu, on the Big Island of Hawaii.
