This digital elevation model provides a tool for calibrating tsunami risk to observations of the 1945 Makran tsunami in Karachi Harbour. The DEM bathymetry is derived from soundings made mainly during the first eight years after the tsunami. Although deficient in portraying intertidal backwaters and upland topography, the DEM accurately depicts the sheltered setting of one of the two tide gauges that recorded the 1945 tsunami.

This product is the result of a comprehensive compilation of site-specific ground photographs taken where tectonic faulting and ground failure produced visible deformation that fractured and disturbed the ground surface. The resultant data is distributed as collection of JPEG image files. All post-earthquake photographs taken by investigators working for public agencies are in the public domain, including data that have been published in summary reports elsewhere. These photographs are best viewed in context with fault rupture and other observations from the related KMZ file of summary field observations and photographs (https://www.sciencebase.gov/catalog/item/5c1d7ae0e4b0708288ca1322), or from the associated open-file...

This item contains a collection of ground photographs taken at the observation stations listed in the above title, showing tectonic faulting and/or ground deformation features produced by the Mw 6.0 South Napa earthquake of August 24, 2014. It is a subset of the a larger collection of photographs found at Photographs of Fault Rupture and Ground Deformation Features Produced by the Mw 6.0 South Napa Earthquake. These photographs may be viewed or downloaded here, but are best viewed in context with fault rupture and other observations from the related KMZ file of summary field observations and photographs obtained during post-earthquake investigations of the Mw 6.0 South Napa Earthquake of August 24, 2014, or from...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
