Magnitude 9.2: The 1964 Great Alaska Earthquake

Magnitude 9.2: The 1964 Great Alaska Earthquake is a short video relating how the largest quake in U.S. history had profound and lasting impacts on our lives. The video features USGS geologist George Plafker who, in the 1960's, correctly interpreted the quake as a subduction zone event. This was a great leap forward in resolving key mechanisms of the developing theory

HVO geologist shields face from intense lava-flow heat while taking a fresh sample.

An HVO geologist shields his face from the intense heat as he takes a sample of active lava on the Kahaualeʻa 2 flow, Kilauea Volcano Hawaii.  The chemistry of the lava is analyzed through time and used to study changes in the magmatic system.

Aerial view toward the southwest of the actively erupting cone within Veniaminof caldera. The white steam plume is produced where a lava flow is descending the side of the cone and melting snow and ice. The darker colored, ashy plume is rising in bursts from the active vent. Nearly continuous eruption from this vent since early June has built a new small tephra cone and an
