Earthquakes are old news. The new natural disaster power player in Los Angeles is the exotically-named tsunami that we all think are relegated to Asian countries and sci-fi flicks despite there being signs everywhere on the Los Angeles coasts that warn against them. But a U.S. Geological Survey says that if Alaska had a 9.1 quake off their shores, the quake could ostensibly create a tsunami large enough to wipe out Long Beach and parts of Orange County, creating devastation big enough to make 750,000 to flee. That's not the worst of it; sewage would flood the cities and toxic debris would ruin everything around the beaches. It would be a bitch to clean up and totally not gnarly, dude. That is one wave we wouldn't want to ride.
