LA quake could top Katrina

Washington - As many as 18 000 people dead. More than $250bn in damages. Hundreds of thousands of people left homeless.

That's not the latest estimate of Hurricane Katrina's toll on the Gulf Coast. That's a worst-case scenario if a major earthquake were to hit Los Angeles.

The figures are hypothetical, from a model published in May by government researchers studying the Puente Hills fault under the city.

Scientists warn that there's little doubt a major quake will hit California in coming years or decades, though many scenarios are not as disastrous as Puente Hills.

As was the case with Katrina, experts say the federal government hasn't done enough to prepare.

"There's not enough money to carry out the research and implementation programmes that need to be put into place," said Susan Tubbesing, executive director of the Earthquake Engineering Research Institute in Oakland, California.

"If funds were available, if these were higher priorities, these kinds of things could be addressed now - before an earthquake."

California has been hit by significant quakes about every 15 years over the past century. Experts say there's a better-than 60% chance that a quake with a magnitude around 6.7 will hit Southern California or the Bay Area within decades.

"The reality is when you have a disaster of that proportion, you need the federal government," Los Angeles Mayor Antonio Villaraigosa said in Washington, where he was meeting with federal officials.

'Too little was done'

Just as Katrina exposed a failure to sufficiently strengthen the levees around New Orleans, experts say a big quake in California, Washington state or the Mississippi Valley could reveal that too little was done to make buildings, bridges and roads earthquake-proof.

"There's very little mitigation going on, and it's because it's so expensive to do, just like it was so expensive to fix the levees," said Chris Poland, head of Degenkolb Engineers in San Francisco. "So I think we would have the same reaction: Why didn't we fix those buildings? Why didn't we fix the infrastructure?"

Congress created the National Earthquake Hazards Reduction Programme in 1977 after a series of major quakes in Alaska, California and China. The goal was to reduce the loss of life and property by funding research on how buildings and structures respond to earthquakes, improving building codes, and conducting earthquake models along different fault lines.

But funding for the programme has been essentially flat for more than a decade.

In California, where earthquake risk is highest, the US Geological Survey has about 140 employees working on earthquake issues under the joint federal programme, down from more than 300 a decade ago, said William Ellsworth, chief scientist with the earthquake hazards team at USGS in Menlo Park, California.

According to some experts, earthquake readiness has been hurt by the same shift of focus from natural disasters to terrorism that's being partly blamed for the bungled response to Katrina.

Michael Buckley, deputy director of Fema's mitigation division, denied there had been a decreased focus on disaster preparedness or mitigation, and said Fema's work on earthquake preparedness has led to successes such as improved building code recommendations.

California has instituted new building codes and spent billions to shore up old structures.

But many older buildings still need upgrades, including some 900 hospital buildings in California, and scientists would like to do more research to learn more about how to build structures that can withstand earthquakes.
