Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake, Volcano, LANDSAT and Water information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted. For more information, please see www.doi.gov/shutdown.
The new lava lake in Pu‘u ‘Ō‘ō has buried much of the floor of the August 3, 2011, collapse crater beneath a maximum of about 45 m (~148 ft) of lava. Most of the lava upwells at the east end of the lake (lower right) and flows toward the west, much like the lava lake prior to the August 3 flank breakout and crater collapse.
This photo, similar to the previous, was taken from the same location as photos posted on July 21 and June 9 (and several other dates scattered over the past several months) to provide a comparison to past activity in Pu‘u ‘Ō‘ō.
