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.
This thermal image, looking northwest, shows the active flows east of Pu‘u ‘Ō‘ō. Bright yellow portions of the image represent areas of active lava. A short channelized flow was active on the upper east flank of the cone, with most activity— comprising pāhoehoe (center of image)—heading southeast. These pāhoehoe flows had reached about 2.6 kilometers (1.6 miles) from the vent during today's overflight.
