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.

View to the SW at the new fissure eruption between Pu‘u ‘Ō‘ō and Nāpau. Cracks in the foreground could be seen opening as photo was being taken.

Fissures actively propagating during Kamoamoa eruption, Kīlauea, Hawai‘i. View looking at the NE end of the actively propagating fissure. Lava is just breaking the surface in foreground crack. Lava reached the surface along an actively propagating fissure during Kīlauea Volcano's Kamoamoa eruption on March 5, 2011.

A channelized flow was being erupted today from the vent on the west side of the floor of Pu‘u ‘Ō‘ō.

Following several collapses and small explosive events that deposited spatter on the floor of Halema‘uma‘u crater around noon today, the lava surface in Halema‘uma‘u was roiling and agitated for the remainder of the afternoon, with numerous points of upwelling and spattering.

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.

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.

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.
