Hawaii's Kilauea volcano erupts, lava fountains form in park

HONOLULU (AP) — One of the most active volcanos on Earth is erupting on Hawaii’s Big Island.
Officials with the U.S. Geological Survey confirmed Wednesday that an eruption has begun in Kilauea volcano’s Halemaumau crater at the volcano’s summit.
Webcam footage of the crater showed lava fountains covering the floor of the crater and billowing clouds of volcanic gas were rising into the air. The same area has been home to a large lava lake at various times throughout the volcano’s eruptive past.
The eruption is not in an area with homes and is entirely contained within Hawaii Volcanoes National Park.

Sitting atop a different massive hot spot (dormant volcano for now) I wonder when things will start shaking around here. Seems like a lot of volcanoes are going off lately.
Off the eastern coast of the island of Mayotte, a gigantic new feature rises 820 meters (2,690 feet) from the seafloor, a prominence that hadn't been there prior to an earthquake that rocked the island in May 2018.
Between 25 February and 6 May 2019, this network detected 17,000 seismic events, from a depth of around 20 to 50 kilometers below the ocean floor – a highly unusual finding, since most earthquakes are much shallower. An additional 84 events were also highly unusual, detected at very low frequencies.
Below the new volcano, tectonic processes may have caused damage to the lithosphere, resulting in dykes that drained magma from a reservoir up through the crust, producing swarms of earthquakes in the process. Eventually, this material made its way to the seafloor, where it erupted, producing 5 cubic kilometers of lava and building the new volcano.
As of May 2019, the extruded volume of the new volcanic edifice is between 30 and 1,000 times larger than estimated for other deep-sea eruptions, making it the most significant undersea volcanic eruption ever recorded.
"The volumes and flux of emitted lava during the Mayotte magmatic event are comparable to those observed during eruptions at Earth's largest hotspots," the researchers wrote.
"Future scenarios could include a new caldera collapse, submarine eruptions on the upper slope or onshore eruptions. Large lava flows and cones on the upper slope and onshore Mayotte indicate that this has occurred in the past.
