A video on USGS EROS monitoring of the 2004 Indian Ocean earthquake and tsunami.
 

Compilation video of significant events from the dome-building eruption at Mount St. Helens, from October 1, 2004 to March 15, 2005, including steam and ash eruptions, growth of lava spines, helicopter deployment of monitoring equipment, collection of lava samples, and FLIR thermal imaging of rock collapse on lava dome.

By late October 2004, a whaleback-shaped extrusion of solid lava (called a spine) emerged from Mount St. Helens' crater floor. The 2004–2008 lava dome grew by continuous extrusion of degassed lava spines that had mostly solidified at less than 1 km (0.62 mi) beneath the surface.

The rockslide occurred about nine miles east of Glenwood Springs in Glenwood Canyon (Colorado) at 7:42 am, November 25, 2004, according officials from the Colorado Department of Transportation (CDOT).

The Revolution in Mapping at the U.S. Geological Survey

by Susan P. Benjamin, Research Geographer

Following unrest that began on September 23, 2004 and the steam and ash eruptions in early October, extrusion of solid magma typified the 2004-2008 eruption at Mount St. Helens. The magma is unusually gas poor and crystal rich.  Several meters of pulverized, variably sintered rock commonly coat the emergent lava spines, lending them a smooth appearance.

On October 11, 2004, spines of solid, but still hot, lava punctured the surface of the deformed glacier, initiating a new dome-building phase of activity in the crater of Mount St. Helens. By late October, a larger whaleback-shaped extrusion of solid lava (called a spine) emerged from the crater floor.

After two weeks of increasing seismicity, Mount St. Helens began erupting on October 1, 2004. The first of several explosions shot a plume of volcanic ash and gases into the atmosphere. Four additional steam and ash explosions occurred through October 5, and three produced noticeable fallout of fine ash downwind.

The Trans-Alaska Pipeline story-- so far, so good!

On October 1, 2004, an explosion in the crater of Mount St. Helens sent ash and water vapor several thousand feet into the air. It was the dramatic beginning of an eruption that continued for the next 3+ years. The explosion fractured Crater Glacier and hurled rocks for at least one-half mile across the western half of the glacier and the 1980-1986 lava dome.

Hear about some of the scientific highlights from 1954 to 2004 --

A time lapse camera was poised on the southern flank of Pu'u 'O'o cone from early 2004 through mid-2007. This location overlooked the Martin Luther King (MLK) vent and provided a distant view of the top of the Prince Kuhio Kalanianaole (PKK) tube system—the lava tube system active at Pu'u 'O'o from 2004 to 2007.

(March 2, 2004, 11:48:17 to 23:08:42) Late 2003 through early 2004 marked a period of heightened eruptive activity at Pu‘u ‘Ō‘ō (Miklius and others, 2006) on Kīlauea Volcano's east rift zone, with lava frequently spilling from vents within the Pu‘u ‘Ō‘ō crater.
