Earthquakes, but no eruption, at Hawaii volcano

Geologists say they've detected a swarm of earthquakes at Hawaii's Kilauea volcano and they though it is not erupting. The Hawaiian Volcano Observatory says the quakes began overnight Monday and continued into the morning. More than 140 earthquakes were recorded as of 4:30 a.m.

The largest was magnitude 3.3. Most were less than magnitude 1. The observatory says that may indicate magma was moving beneath the south part of Kilauea's caldera. The observatory changed its volcano alert level to watch from advisory, meaning Kilauea is showing heightened unrest with more potential for an eruption.
