DESCRIPTION Eric Cohen, find an .AVI format movie showing slow moving aa lava. Whether the lava is aa or pahoehoe depends mainly on viscosity and strain rate. These two factors, in turn depend on crystallinity, dissolved gas content, temperature, bubble content, slope, eruption rate, and lava composition. See `Lava flow types`

DESCRIPTION Freeman, this Real Player format animation shows the eruption of a cinder cone from a three dimensional perspective. The cinder cone is comprised of cinders fountaining from a central vent, is normally basaltic or andesitic in composition, and is usually less than 300 meters in height. The steepness of the slope is a function of ejecta coarseness, wind direction, and eruption height.

DESCRIPTION Freeman, this Flash animation recounts the formation of the Hawaiian Island chain. The Islands` formation is linked to a hot spot beneath the Pacific Plate and the plate`s on going movement to the northwest and west. To access the animation, click on chapter 6, then the `volcanism` link in the animations section.

DESCRIPTION McGraw Hill, though less sophisticated than the Freeman link on hot spots, this Flash animation shows the formation of fringing reefs around the island and the eventual formation of an atoll. To access the animation click on the `Hot Spots and Aseismic Ridge` link.

DESCRIPTION a QuickTime animation depicts the Kamoamoa lava flow of 1995 on Mt. Kilauea in Hawaii. Note the relatively gentle slope and slow rate of lava movement of this shield volcano. At other times, the lava can be quite fluid and can move at quite rapid rates

DESCRIPTION this Real Media format movie shows actual footage of the blast sequence. The video begins with pictures of how Mt. St. Helens looked before the eruption, then shows the eruption itself.

DESCRIPTION McGraw Hill, a Flash animation recounting the factors responsible for the Mount St. Helens eruption. After a landslide and pyroclastic flow there were blasts at the summit and flank of the volcano. It would be helpful if the animation could be replayed easily to recount each of the steps preceding the eruption.

DESCRIPTION Savage Earth, the third frame in this Flash animation is helpful in showing how a pyroclastic flow particles becomes differentiated with heavier particles sinking and the lighter particles and gases displaced upwards. Pyroclastic flows can travel at speeds exceeding 100 miles per hour and can be over 1000 degrees F. Over the years, these dangerous flows have killed thousands.
