Mauna Loa, Earth's largest active volcano, has erupted 33 times since 1843, producing the lava flows shown in black. All of these historic eruptions started at the summit of the volcano. From there, the eruptions either stayed in the summit area or migrated down the volcano's Northeast or Southwest Rift Zones.

Mauna Loa tends to erupt large, fast-moving lava flows. About 36 hours after the 1984 eruption began on March 25, lava flowed downstream (toward bottom-right of photo) through this ‘A‘ā channel down rift from the main vent. For scale, note the USGS scientists at work on the left side of the 70-m- (77-yard-) wide lava channel.

A bursting bubble on the surface of a lava lake produces an impulsive signal on an infrasound recording. This photo shows a group of bubbles about 5 m (16 ft) across bursting on the Halema‘uma‘u lava lake at the summit of Kīlauea Volcano. The blue line is an infrasound recording of 50 seconds of similar activity.

Early evening view of the lava lake within Halema‘uma‘u crater at the summit of Kīlauea Volcano on January 30, 2018, when the lake level was 27 m (88 ft) below the crater floor. The bright yellow area of spattering marks the location where the circulating lava descends into the lake, thereby releasing gases trapped beneath the solid black crust on the lake surface.
