movie (x3 speed) shows the latest explosive eruption from the vent in Halema`uma`u, which occurred at 7:28am. A robust, ash-rich mushroom cloud is ejected, and followed by pulses of hot, glowing gas and particles. The explosion deposited a field of fist-size ejecta around the crater rim.

movie of the October 12 explosive eruption captured by a camera located on the rim of Halema`uma`u just above the vent. The camera was completely engulfed in the ash cloud, turning day to night, then bombarded by falling ejecta.

On October 12, 2008, an explosive eruption, shown in this video, blasted lithic and juvenile tephra onto the Halema'uma'u crater rim 85 meters (280 feet) above the informally-named Overlook vent (see http://hvo.wr.usgs.gov/kilauea/timeline/ for links describing eruptive activity at the summit of Kilauea Volcano)

movie (x3 speed) shows an ash event from the vent in Halema`uma`u, occurring at 3:54 pm. The normally white degassing plume is rapidly overwhelmed with a vigorous ash-rich pulse that rises rapidly from the vent. Red flashes above the vent indicate hot, incandescent material being ejected.

The 1989 Loma Prieta Earthquake was not the Bay Area's "Big One" but a repeat of the destructive 1868 Hayward earthquake may qualify!

The size and distribution of grizzly bear populations in northwest Montana has just been released by the USGS, so research biologist Kate Kendall bring us up to speed on the findings.

Movie shows a roiling, bubbling lava surface approximately 100 yards beneath the rim of the vent within Halema`uma`u. This is the first clear view of lava within the vent, which opened on March 19, 2008. The video was taken from a helicopter hovering over the Halema`uma`u overlook area.

Movie, in 'nightshot' mode and zoomed in on the Halema`uma`u vent, shows the explosive eruption which occurred at 8:13 pm. This eruption carpeted the area around the Halema`uma`u crater rim with ejecta as large as 8 inches long.

An explosive eruption from the informally-named Overlook vent at Kilauea's summit (see http://hvo.wr.usgs.gov/kilauea/timeline/ for links describing eruptive activity at the summit of Kilauea Volcano) occurred on September 2, 2008.
