Tsunami Risk Along the California Coast

Data: Tsunami Risk Along the California Coast

Abstract:

This service provides maps of tsunami flood hazard. The tsunami zones are based on consideration of local tsunami-generating sources offshore California’s coasts (earthquake faults and landslides), and distant sources around the Pacific Ocean rim. These zones are non-regulatory and currently include zones that are intended to provide guidance for emergency planning purposes only. Additional zones may be provided in the future that provide guidance for use in coastal land use and construction. More information is available from the California Geological Survey (http://www.consrv.ca.gov/cgs/geologic_hazards/Tsunami/Inundation_Maps/Pages/Statewide_Maps.aspx) and the California Emergency Management Agency (http://cms.calema.ca.gov/prep_tsunami.aspx)

Applying ecological principles

Ecological principles represent the core attributes of natural systems that must be maintained or restored in order to support healthy marine and coastal ecosystems, and include maintaining, restoring, or accounting for:

These principles are explained in a reference guide for agencies in California, called the Ecological Principles Guide . This guide also includes a series of case studies and checklists that demonstrate how the principles can be applied to day-to-day decision making.

State GeoPortal

The EcoPrinciples Connect tool links to data from the California Geoportal, which offers an easy and convenient way to search, discover and use authoritative geospatial data resources. This one-stop geospatial shop is helping to improve access to California’s geographic data portfolio and expand the use of those data resources in decision making processes.
