A view of the spattering source from the ground.

This thermal image was taken from a helicopter above the active fountains at the west end of the fissure system. There were two adjacent fountaining areas, with one situated within a spatter cone and the other bursting through a perched lava pond. The fountains were feeding a channelized flow that can be seen in the upper right portion of the image.

This thermal image shows the channelized ‘A‘ā flow that was being fed by the fountains at the west end of the fissure system today. Near the end of the flow, the channel empties into the delta-like flow front.

On the west end of the fissure system, spatter ramparts are forming as the lava fallout solidifies in a mound upwind from the source.

A broad view of the Kamoamoa fissures. The fissures extend 2.3 km (1.4 mi) between Nāpau Crater and Pu‘u ‘Ō‘ō. The western most fissure is just out of view in this photo.

The eastern vent complex of the Kamoamoa eruption was inactive today, but it continues to emit a thick gas plume.

The western vent complex continues to erupt, and had been doing so for about 30 hours as of the time of this photo. Lava erupting from the vent complex is flowing into a channel with levees.

By early this morning, the front of the ‘A‘ā flow fed from the western vent had intercepted the edge of the Mother's Day flow, which was emplaced in 2002-2004. The flow advanced about 2.9 km (1.8 miles) in 30 hours.

With lava retreating deeper into the Halema‘uma‘u vent cavity over the past two days, the cavity walls have experienced more frequent collapses. At 2:23pm today, a collapse from the upper portion of the vent cavity produced a robust brown plume, but did not eject any large particles.

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. Reddish-brown is the flow as mapped on February 4, 2011, while bright red shows the advancement of the flow from January 13-February 4. Small ocean entries remains active at the front of both the western and eastern branches of the flow.

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

Map showing the extent of the "July 2007 eruption", or Episode 58, flow field relative to surrounding communities. Reddish-brown is the active flow as mapped on January 13, 2011, while bright red shows the advancement of the flow from January 13-February 4. Light red represents older flows erupted during Episode 58 of the ongoing East Rift Zone eruption.
