The United States Geological Survey (USGS) Hawaiian Volcano Observatory (HVO) has been monitoring the recent activity of the Kilauea volcano on the island of Hawai’i.
At 1:42 p.m. HST this afternoon, USGS Hawaiian Volcano Observatory (HVO) monitoring network detected the onset of rapid deflation at Pu`u `Ō `ō and increased tremor along Kīlauea Volcano’s middle east rift zone. At 2:00 p.m., Kīlauea’s summit also began to deflate.
Between 2:16 and 2:21 p.m., the floor of the Pu`u `Ō `ō crater began to collapse, and within 10 minutes, incandescent ring fractures opened on the crater floor a few tens of meters away from the crater wall. Asthe floor continued to drop, lava appeared in the center of the crater floor, the northeast spatter conewithin Pu`u `Ō `ō collapsed, and an obvious scarp developed on the west side of the crater floor, withlava cascading over the scarp toward the center of the crater.
At 2:41 p.m., the scarp on the west side of the crater floor appeared to disintegrate, exposing incandescent rubble. Five minutes later, the collapse of a large block along the east crater wall produced a dust plume.
Webcam images showed that the Pu`u `Ō `ō crater floor continued to drop through 4:26 p.m., when fume obscured the camera view. [source]
Scientists have found that the Pu’u ‘O’o crater floor dropped at least 115 m (377 ft) during the collapse.
Kilauea activity can be viewed via the webcams provided by the USGS HVO, listed here. However, at times the cameras are obscured by volcanic fumes. Continual updates can be found at the Kilauea status page found here.
