Depth-averaged currents and distribution of near-surface specific conductance in coastal Lake Erie in the vicinity of Villa Angela Beach and Euclid Creek, Ohio on September 11, 2012 Produced in VMT using data from a TRDI 600 KHz Rio Grande ADCP and supplementary specific conductance data from an autonomous underwater vehicle (AUV) that completed a simulataeous three

Map of earthquakes greater than M1.5 that occurred between March 1 and May 12, 2020, in the Intermountain West. The main shock-aftershock sequences in central Idaho and near Salt Lake City are labeled. Orange dots are earthquakes that occurred within 24 hours, and yellow 1 week, of the map being generated (May 12, 2020)

Schematic diagram illustrating the difference between a main shock with aftershocks (top), a sequences of foreshocks, main shock, and aftershocks (middle), and a seismic swarm (bottom).  Adapted from manuscript by Farrell and others, 2009.

A small rockslide occurred today on the south wall of Halema‘uma‘u, sending boulders into the water at the bottom of the crater. USGS video by M. Patrick.

A view from the south rim of Halema‘uma‘u shows a lower collapsed block which has remains of Crater Rim Drive and the Halema‘uma‘u parking lot. The white feature in the lower right is a stop sign that was present at the eastern exit of the parking lot.
