EAGER: Pilot Fiber Seismic Networks at the Amundsen-Scott South Pole StationThis EAGER award will explore the Distributed Acoustic Sensing emerging technology that transforms a single optical fiber into a massively multichannel seismic array. This technology may provide a scalable and affordable way to deploy dense seismic networks. Experimental Distributed Acoustic Sensing equipment will be tested in the Antarctic exploiting unused (dark) strands in the existing fiber-op

Collaborative Research: Imaging Seismic Heterogeneity within the Antarctic Mantle with Full Waveform Ambient Noise TomographyOur project is focused on better resolving the three-dimensional Antarctic mantle structure to further understanding of continental tectonics. To accomplish this, we are utilizing a full-waveform tomographic inversion technique that incorporates long-period ambient noise data and which has been shown to more accurately resolve structure than traditional tomographic approaches. The new models have

Shear Wave Structure of Umbria and Marche, Italy, Strong Motion Seismometer Sites Affected by the 1997-98 Umbria-Marche, Italy, Earthquake SequenceA long sequence of earthquakes, eight with magnitudes between 5 and 6, struck the Umbria and Marche regions of central Italy between September 26, 1997 and July 1998. The earthquake swarm caused severe structural damage, particularly to masonry buildings, and resulted in the loss of twelve lives and about 150 injuries. The source of the events was a single seismogenic structure that consists of se

Modified Mercalli Intensity Maps for the 1868 Hayward Earthquake Plotted in ShakeMap FormatThis data set provides Modified Mercalli Intensity maps for the Hayward earthquake of October 21, 1868. To construct the Modified Mercalli Intensity (MMI) ShakeMap for the 1868 Hayward earthquake, we started with two sets of damage descriptions and felt reports. The first set of 100 sites was compiled by A.A. Bullock in the Lawson (1908) report on the 1906 San Francisco earthquake. The second set

Liquefaction-Induced Lateral Spreading in Oceano, California, During the 2003 San Simeon EarthquakeThe December 22, 2003, San Simeon, California, (M6.5) earthquake caused damage to houses, road surfaces, and underground utilities in Oceano, California. The community of Oceano is approximately 50 miles (80 km) from the earthquake epicenter. Damage at this distance from a M6.5 earthquake is unusual. To understand the causes of this damage, the U.S. Geological Survey conducted extensive subsurface

National Seismic Hazard Maps from the USGS National Seismic Hazard Mapping ProjectThe National Seismic Hazard Mapping Project (NSHMP) provides online maps. The hazard maps depict probabilistic ground motions and spectral response with 10%, 5%, and 2% probabilities of exceedance (PE) in 50 years. These maps correspond to return times of approximately 500, 1000, and 2500 years, respectively. The maps are based on the assumption that earthquake occurrence is Poissonian, so that th
