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 flow front of the June 26 breakout (pictured above) has stalled. On the coastal plain today, the closest active breakouts found by HVO geologists were 2.1 km (1.3 miles) upslope from the emergency route. There were a few areas of active pāhoehoe breakouts which varied from sluggish ropey textures to thin and fluid flows.
Cracks on the Kamokuna lava delta continue to develop. These photos from July 31 (left) and today, August 15 (right), highlight changes on the delta during the past two weeks. The yellow numbers mark a few prominent features on the delta (1 & 3) and older sea cliff (2 & 4). A new crack (1) formed over the two weeks and appears to span most of the delta, and a crack closer to the cliff (3) has widened and extended to the west. Time-lapse images during the past two weeks showed slight widening of the large crack and subtle subsidence of the delta. Continued development of these and other cracks underline the hazardous nature of an ocean entry, and why it is important to take heed of all warning signs and area closures.
