Changes on Kīlauea's ERZ

Changes on Kīlauea Volcano's East Rift Zone...

Detailed Description

Starting at about 2:00 p.m. on Monday, April 30, marked increased seismicity and ground deformation indicated that the expected change at Pu‘u ‘Ō‘ō was underway. Visibility was nearly obscured due to poor weather conditions, but a brief clearing at 2:12 allowed HVO's webcam to capture this image of the crater, showing that part of the crater floor within Pu‘u ‘Ō‘ō on Kīlauea Volcano's East Rift Zone had collapsed. The crater floor continued to collapse for several hours therafter; smaller drops in the crater floor have likely continued through today (May 1).
