Hawaiian Volcano Eruption

March 7, 2011

Crater Floor Collapses




On March 5th the crater Pu'u 'O'o collapsed and a fissure opened on Kilauea's east rift zone that caused lava to erupt. On the next day there was sporadic fissures and activity and lava spattering up to 80 feet high. The particular crater that was located in a remote region on the west-southwest of Hawaii causing the National Park to close. During the collapse the Pu'u 'O'o crater the floor dropped around 377 feet, only showing cascading rock fragments. Over the next couple of days the lava flows along the pali and coastal plain were sluggish but quite active, and expected to flow for the next couple of days. At the peek of Kilauea's summit the lava lake inside begun to recede deep within the vent on Halema'uma'u Crater. There are also earthquakes that have occurred in the Napau Crater area near the fissure eruption, though in the next couple of days these would also slowly deflate.
