Measuring the thickness of an ‘A‘ā flow produced by the Kamoamoa fissure eruption. The measuring stick is 2 m (6.5 ft) tall.

A massive earthquake, and subsequent tsunami, struck the northeast coast of Japan on Friday, March 11, 2011. The USGS calculated the magnitude of the earthquake as a 9.0, the fourth largest ever recorded. The tsunami that followed was over 10 meters high in places.

Map showing the extent of the active flows of the Kamoamoa eruption, which started on March 5, 2011. Bright red shows the currently active flow, and light red shows an incomplete mapping of recent, but inactive, flows. Dark gray is the exposed area of flows erupted between 1983 and 1992, while light gray shows the extent of flows erupted from 1992 to 2007.

Aerial view of Pu‘u ‘Ō‘ō and surrounding features.

Most of the day's activity was focused at this vent, around which a low cone was forming. Pu‘u ‘Ō‘ō is visible in the background to the northeast.

Lava pours from the fissure just after daybreak and cascades out of sight into a deep crack. HVO geologist near upper right for perspective.

A portion of charred, lava covered forest along the east rift zone, from the initial fissure eruption that began yesterday evening (March 5).

A small fissure eruption between Pu‘u ‘Ō‘ō Crater and Nāpau, extending 100 m long (330 ft) and spattering 20 m (66 ft) high.

A close-up of the fissure just west of Pu‘u ‘Ō‘ō Crater. Spatter was reaching heights of 40 m (130 ft).

Photo taken at dawn of a fissure erupting between Pu‘u ‘Ō‘ō Crater and Nāpau.

This fissure began in the early hours of March 6, erupting spatter and producing lava flows.

Spatter reaching up to 30 m (100 ft) from a fissure that opened this morning.

Increased activity on one of the new fissures between Pu‘u ‘Ō‘ō Crater and Nāpau.

Ash cloud rising from Pu‘u ‘Ō‘ō as crater floor collapses due to magma withdrawal. Incandescent rubble can be seen crumbling and rolling down the scarp. The east rim of Pu‘u ‘Ō‘ō is in the foreground.

Incandescent rubble rolling and sliding down the scarp on the edge of the collapsing crater in Pu‘u ‘Ō‘ō. A remnant of the pre-collapse crater floor can be seen in the background below the crater's south wall. The east rim of Pu‘u ‘Ō‘ō is in the foreground.
