We have excavated approximately 130 species of fish from this deposit over the last 35 years.
The site also contains well preserved arthropods, sponges, starfish, conulariids, worms, and other soft-bodied organisms, as well as brachiopods, bryozoans, and molluscs.
A mild eruption may simply discharge steam and other gases, or quietly extrude lava.
A strong eruption can consist of violent explosions that send great clouds of gas-laden debris into the atmosphere, or may consist of explosions that blast sideways from a collapsed portion of the volcano, as happened in the 1980 eruption of Mount St. Eruptions can alter the land and water locally through lava flows, lahars, pyroclastic flows, and landslides.
