Today marks the 10th anniversary of the eruption within Halema‘uma‘u at the summit of Kīlauea Volcano. When the vent first opened on March 19, 2008, it formed a small pit about 115 feet (35 m) wide. Over the past decade, that pit (informally called the "Overlook crater") has grown into a gaping hole about 919 feet by 656 feet (280 x 200 m) in size.

TEB rootless shield flank failure
(January 26, 2008, 10:50:12 to 19:12:16) Perched lava ponds often formed atop the rootless shields built by the "Thanksgiving Eve Breakout" (TEB) lava flow. This movie shows the failure of the flank of a rootless shield on January 26, 2008, and the release of the lava contained within the perched lava pond at its summit.

Time-lapse images of Mount St. Helens dome growth 2004-2008
The rapid onset of unrest at Mount St. Helens on September 23, 2004 initiated an uninterrupted lava-dome-building eruption that continued until 2008. The initial phase produced rapid growth of a lava dome as magma pushed upward.

TEB effusion and partial rootless shield flank failure
(December 1, 2007, 02:01:38 to 16:01:36) On November 21, 2007—the eve of the U.S. Thanksgiving holiday—Episode 58 changed dramatically. Lava, erupting from Fissure D into a perched lava channel, found an easier path to the surface and broke out from directly over Fissure D on what was, by then, the southern flank of the channel.

Episodic spattering in the Episode 58 lava channel
(November 15, 2007, 09:00:15 to 13:00:15) Periods of overflow and levee construction at the Episode 58 lava channel were interspersed with periods when the lava level was below the channel rim. The lava surface within the lava channel commonly experienced repeated cycles of rise and fall, as shown here.

Video Highlights:
* A catastrophic 1982 rainstorm triggered 18,000 landslides in the Bay Area, claiming 25 lives and causing $66 million in property damage
* The combination of steep slopes, weak rocks, and intense winter storms make Bay Area uplands an ideal setting for landslides
