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.

At 2:31pm today, another large chunk of the rim collapsed into the Halema‘uma‘u lava lake.

Just moments after the last photograph, the 2:31pm collapse produced a thick brown plume, but did not appear to trigger an explosive event in this case.

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.

This fissure is erupting 1.5 km (0.9 mi) west of Pu‘u ‘Ō‘ō Crater. You can view this eruption on the new Pu‘u ‘Ō‘ō to Nāpau Crater webcam installed today!

A sailboat gets stuck under the Murray Street bridge over Santa Cruz Harbor in California, after it was washed free of its dock due to the strength of the tsunami wave from Japan. While the tsunami energy that hit the coast of California was relatively low, the wave energy is concentrated in narrow spaces like harbors.

These tephra deposits are from the Kulanaokuaiki Tephra erupted from Kīlauea Volcano about 200 to 1000 C.E. The base of a lava flow overlying the tephra is just above the person's hand. This site is located near the base of Kīlauea's summit crater wall, directly below the USGS Hawaiian Volcano Observatory and NPS Jaggar Museum.

Views into the Halema'uma'u vent have been largely obscured by fume over the past several days, and the only consistent views have been with a thermal camera, which can "see" through the fume. This thermal image was taken at a nearly vertical angle from a helicopter, in order to see the bottom of the extremely deep and narrow vent cavity.
