Tsunami Source Standardization for Hazards Mitigation in the United States

The goal of this Powell Center Working Group is to produce a collection of vetted and standardized earthquake and landslide tsunami sources that can be used to produce the meaningful hazard assessment products required for effective tsunami hazard mitigation and risk reduction. The need for a set of realistic and consistent tsunami sources was identified as a high priority at a 2016 workshop betwe

Minisparker and chirp seismic reflection data acquired offshore San Francisco and Pacifica during USGS field activity S-16-10-NC

Chirp sub-bottom and single-channel minisparker seismic reflection data were collected by the U.S. Geological Survey in August 2010, offshore San Mateo County, California. Data were collected aboard the R/V Snavely during field activity S-16-10-NC. This work was funded by the USGS Coastal and Marine Geology Program's Coastal and Marine Catastrophic Hazards project. The high-resolution seismic-refl

Simulation and visualization of coastal tsunami impacts from the SAFRR tsunami source

To further extend the scope of the Science Application for Risk Reduction (SAFRR) project, detailed hydrodynamic simulations were run at three harbor locations in California. For the locations of 1) Oakland/Alameda, 2) Half Moon Bay, and 3) Santa Cruz, simulations at approximately 5-m resolution were performed using the high-order Boussinesq-type model COULWAVE. The Oakland/Richmond simulation are

SAFRR tsunami scenario: Impacts on California ecosystems, species, marine natural resources, and fisheries

We evaluate the effects of the SAFRR Tsunami Scenario on California’s ecosystems, species, natural resources, and fisheries. We discuss mitigation and preparedness approaches that can be useful in Tsunami planning. The chapter provides an introduction to the role of ecosystems and natural resources in tsunami events (Section 1). A separate section focuses on specific impacts of the SAFRR Tsunami S

The SAFRR tsunami scenario: improving resilience for California

On March 11, 2011, the Tohoku earthquake and the resulting tsunami devastated Japan with a disaster of unfathomable proportions. Five thousand miles away, the waves from Tohoku caused $50 to 100 million in damages in California. Although this pales in comparison to the loss of lives and property in Japan, the U.S. Government must ask whether California, and the national economy, will someday face

The SAFRR Tsunami Scenario

The U.S. Geological Survey and several partners operate a program called Science Application for Risk Reduction (SAFRR) that produces (among other things) emergency planning scenarios for natural disasters. The scenarios show how science can be used to enhance community resiliency. The SAFRR Tsunami Scenario describes potential impacts of a hypothetical, but realistic, tsunami affecting California

Comments on potential geologic and seismic hazards affecting proposed liquefied natural gas site in Santa Monica Bay, California

In a letter to the U.S. Geological Survey (USGS) dated March 25, 2008, Representative Jane Harman (California 36th district) requested advice on geologic hazards that should be considered in the review of a proposed liquefied natural gas (LNG) facility off the California coast in Santa Monica Bay. In 2004, the USGS responded to a similar request from Representative Lois Capps, regarding two propos
