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 June 27 flow remains active, and has advanced further into the forest over the past week. The flow front today was 8.5 km (5.3 miles) northeast of the vent on Pu‘u ‘Ō‘ō (see "map" link above for current flow field map). The flow's continued brisk advance rate is likely related, in part, to its continued confinement by local topography. Today, the narrow flow front was within one of the many linear depressions (grabens) on the East Rift Zone. Pu‘u ‘Ō‘ō can be seen in the distance.
