Anderson Dam Seismic Risk

2011-07-17T12:46:00.000-07:00

The Santa Clara Valley Water District announced the results of a seismic study that determined the 60-year-old Anderson Dam might collapse if a "maximum credible earthquake" of 7.2 magnitude on the Calaveras fault struck within 1.25 miles of the dam. That quake has a less than 1 percent chance of happening. But if by bad luck it did, the sand and gravel in the foundation of the dam would liquefy, causing the structure to fail. READ MORE

California Earthquake Preparedness Survey

2010-03-08T13:08:00.000-08:00

The California Earthquake Preparedness Survey (CEPS) was conducted by the UCLA School of Public Health and Survey Research Center for the State of California. The objective was to provide baseline data describing how prepared California households are for earthquakes and where they get their information about preparedness and mitigation.

Telephone interviews were conducted with a representative sample of 2,081 households in California between June 26 and December 18, 2008. The sample was stratified into: the ten northern California counties at greatest risk of earthquakes, the six southern California counties at greatest risk, and the remaining 42 lower-risk counties.

California's water supply vulnerable to quakes, floods

2009-03-21T09:31:00.001-07:00

The California Department of Water Resources has just released a study that concludes there is a 40 percent chance that a major earthquake will flood 27 delta islands between now and 2030, costing billions in repairs and knocking out the water source for 25 million Californians for more than a year.

Without intervention, it is estimated that about 140 levees of California's could fail in the next century due to storms or rising seas. An earthquake of magnitude 6.7 or greater could result in fatalities, flooding of islands and costs of $15 billion. In California levees have failed about 160 times in the past 109 years. READ MORE

Study shows massive earthquake could cause Anderson Dam to fail

2009-01-06T18:17:00.000-08:00

A study performed for the Santa Clara County Water district indicates that the the largest dam in Santa Clara County could collapse in a major earthquake. DOWNLOAD STUDY

A 6.6 magnitude quake centered directly at Anderson Reservoir near Morgan Hill, or a 7.2 quake centered one mile away, could cause the reservoir's 240-foot-high earthen dam to fail.

In the worst case, a complete failure of Anderson Dam could send a wall of water 35 feet high into downtown Morgan Hill within 14 minutes, and eight feet deep into San Jose within three hours. READ MORE

California Prepares for Potential Flooding

2008-11-28T10:30:00.000-08:00

Due to the potential for flooding, mud flows and debris in and around recent wildfire fire burn areas, the Governor in California has directed his Office of Emergency Services (OES) to work with the Federal Emergency Management Agency (FEMA) and prepare to help local agencies if assistance from the state is needed for expected rains.

Status Report -Long-Term Disaster Recovery Planning by Local Governments in the San Francisco Bay Area

2008-11-07T08:51:00.000-08:00

The Association of Bay Area Governments (ABAG) as part of their Regional Long-Term Disaster Recovery Initiative recently released the "Status Report - Long-Term Disaster Recovery Planning by Local Governments in the San Francisco Bay Area." Long-term recovery refers to the repair and rebuilding process that government departments, such as planning, finance, housing, public works/building, redevelopment, and emergency management, will need to carry out to start restoring their community after an earthquake or other catastrophic disaster. In advance before any disaster, jurisdictions need to be prepared to finance recovery, expedite long-term housing recovery, support recovery of downtown businesses and the local economy, and ensure that their own facilities and services recover smoothly.

The Survey's summary report documents the areas of recovery planning in which local governments are making significant progress, have mixed levels of progress, and where they need to make improvements. The report examines the collective sum of information and analyzes the status of recovery efforts throughout the Bay Area as a whole, rather than focusing exclusively on what individual jurisdictions have done. The reasoning is that a catastrophic disaster is not localized, but affects the whole region.

Next big quake expected to cause billions in damage to Bay Area

2008-10-24T10:37:00.000-07:00

When the Hayward Fault — which snakes from north San Jose to San Pablo — erupts, damage throughout the Bay Area could approach $200 billion. That's more than the combined economic losses from the 1989 Loma Prieta earthquake, 1992's Hurricane Andrew and 2005's Hurricane Katrina, according to geophysicist Mary Lou Zoback of Risk Management Solutions, at a presentation at the recent CONFERENCE ON EARTHQUAKE HAZARDS IN THE EASTERN SAN FRANCISCO BAY AREA. This includes losses due to shaking, fire and ruptures of roads, dams and pipelines. READ MORE
