Hawaii’s Kilauea shows signs of eruption

Scientists monitoring Hawaii's Kilauea volcano raised the alert level due to increased potential for an eruption, indicated by a series of earthquakes and groundswelling. These phenomena suggest magma movement beneath the volcano. From Monday to Wednesday, numerous small earthquakes were detected, but the chances of an eruption decreased as activity subsided, leading to a lowered alert level. In December, Kilauea erupted, creating a lava lake with enough lava to fill 10 Hoover Dams.
