After a long period of rain and low clouds, improved weather and high clouds today allowed good airborne observations of the collapse crater in Pu‘u ‘Ō‘ō. This photo looks to the east, and shows the deep collapse crater formed on Monday, April 30, when magma beneath Pu‘u ‘Ō‘ō drained. For scale, the crater is about 250 meters (820 feet) wide.
