Catalog of Submarine Volcanoes and Hydrological Phenomena Associated with Volcanic Events
	Catalog of Submarine Volcanoes and Hydrological Phenomena Associated with Volcanic Events (by P. Hedervari, 1986) covers the time span of 1900 A.D. through 1959 A.D. The information presented includes submarine eruptions, new volcanic islands, tsunamis, seiches, and base surges related to volcanic activity. 35 pages; soft cover.

Crater Peak (Mt. Spurr), Alaska: Eruptions of 1992
	This set follows the story of Crater Peak activity from June through October 1992. It depicts precursors, the eruptions, and effects on the environment and the population.

Eruption of Mount St. Helens, May 18, 1980
	The Mount St. Helens eruption has afforded geologists a unique opportunity to learn about volcanoes. These slides not only include pictures of the eruption, but pre-eruption activity and post-eruption geomorphology.

Fire vs. Water: The Erosional & Depositional Geology of Hawaiian Islands
	The opposing forces of volcanism and erosion shape Hawaii's dramatic geology. This set shows constructional volcanic features and their subsequent erosion.

Geological Hazard Photos, 1997
	Collection of photographs of damage from natural hazards in TIF, GIF, and JPG formats. Earthquakes, volcanoes, tsunamis, landslides and other geologic hazards are represented.

Hawaii Volcanism: Impact on the Environment
	While not generally life-threatening, Hawaiian lava flows are highly destructive to populated and cultivated areas. This set depicts the impact on communities, vegetation, marine life, roads, and coastlines. It also shows the benefits including geothermal power, increased land area, and research opportunities.

Hawaii Volcanism: Lava Forms
	Over the last several million years, the Hawaiian Islands were built of successive lava flows. These are the most recent additions to a long line of volcanoes trailing to the northwest. This set includes very colorful images of lava fountains, lakes, cascades, flows, spatter, and lava entry to the sea from recent eruptions.

Mount Pinatubo Revisited: A Study of Lahar Erosion
	The 5 to 7 km3 of material deposited in the 1991 eruption of Mount Pinatubo continues to threaten structures and lives in the form of debris flows (lahars) during heavy rainstorms. This set shows how the disaster that began at Pinatubo in 1991continues to threaten the population in the area.

Shield Volcanoes of Hawaii, 2000
	This poster of shield volcanoes shows dramatic images of shield volcanoes built almost entirely of lava flows, and occurring at mid-ocean ridges and hot spots. The Hawaiian shield volcanoes threaten sensitive coastal ecosystems, transportation and communication networks, and populated regions.

Significant Volcanic Eruptions Database
	The Significant Volcanic Eruptions Database contains information for 400 volcanic eruptions incuding the latitude, longitude, elevation, type of volcano, and effects such as deaths, injuries and damage.

Stratovolcanoes of the World, 2000

Stratovolcanoes (also known as composite volcanoes) are built of successive layers of ash and lava. This poster shows many of the most well known eruptions of strato volcanoes. The magma (molten rock) within the volcano is viscous and often contains trapped gas, causing explosive eruptions. Approximately 85% of stratovolcanoes are located around the Pacific Ocean, forming what is called the "Ring of Fire."

Volcanic Ash Advisory Database
	The Volcanic Ash Advisory Databse contains Volcanic Ash Advisory messages and forecasts of ash location in the atmosphere issued by the NOAA Satellite Services Division from 1983 to 2003.

Volcanic Rocks and Features
	Volcanoes are one of the more dramatic manifestations of the dynamic nature of Earth. The rocks and features formed in an eruption reveal a great deal about the process. Pictures show lava types, ash, cinders, bombs, necks, dikes, and sills.

Volcano Location Database
	The Volcano Location Database contains information for over 1500 volcanoes including information on the location, elevation, type and last known eruption. It is a subset of the Smithsonian Institution Global Volcanism Program Volcano Database.

Volcanoes in Eruption, Set 1
	This slide set depicts explosive eruptions, lava fountains and flows, steam eruptions, and fissure eruptions from 19 volcanoes in 13 countries. Volcano types represented include: strato, cinder cone, complex, fissure vent, lava dome, shield, and island-forming. B&W/Color

Volcanoes in Eruption, Set 2
	This set depicts ash clouds, fire fountains, lava flows, spatter cones, glowing avalanches, and steam eruptions from 18 volcanoes in 13 countries. Volcano types include: strato, cinder cone, basaltic shield, complex, and island forming. B&W/Color
