Photo and Video Chronology – Kīlauea – May 7, 2021

Kīlauea's summit eruption continues on the Island of Hawai‘i; Halema‘uma‘u west vent erupts lava into the lava lake, which was 228 m (748 ft) deep this morning, May 7. Gas emissions and seismic activity at the summit remain elevated. HVO field crews—equipped with specialized safety gear—monitor the eruption from within the closed area of Hawai‘i Volcanoes National Park with NPS permission.

Volcano Watch — Tiny changes at Mauna Loa’s summit hold big clues

Although Mauna Loa is Earth’s largest active volcano, it has lived in the shadow of Kīlauea since it last erupted in 1984.  The geologic record shows that Mauna Loa erupts every seven years on average; however, 37 years have passed since lava flows from the volcano’s Northeast Rift Zone came within 7 km (4 miles) of Hilo.

Volcano Watch — The rise and fall of lava lakes

May 3rd marks three years since the start of the devastating lower East Rift Zone eruption of Kīlauea. In 2018, rising summit lava lake levels, caused by building magmatic pressure, culminated in a large eruption on the lower flank which then abruptly drained the summit lava lake and initiated crater collapse.

Volcano Watch — How measuring gravity on Mauna Kea helps us monitor Mauna Loa

Gravimeters, essentially extremely precise pendulums, can measure a change in the force of gravity to one-in-one billionth of the force you feel every day. This force varies based on the distance and the amount of mass between the instrument (or you) and the center of the Earth.
