Tsunamis, Earthquakes Overdue in Lake Tahoe. And why it’s likely to happen on a Tuesday or Wednesday

This is three years old, but considering the subject, it’s relevant to any time.


SAN FRANCISCO — A tsunami-producing fault in Lake Tahoe is overdue for another earthquake, scientists said here yesterday (Dec. 4) at the annual meeting of the American Geophysical Union.

The West Tahoe Fault is capable of producing a magnitude-7.3 earthquake and tsunamis up to 30 feet (10 meters) high in the clear blue lake, where million-dollar homes line the shore, researchers said.

Earthquakes strike every 3,000 to 4,000 years on the fault, and the most recent shaker was 4,500 years ago, indicating the fault is overdue for another earthquake, said Jillian Maloney, a graduate student at the Scripps Institution of Oceanography in San Diego.

Earthquakes Occur More Often on Tuesday and Wednesday:

Another interesting thing is that in the 26 states that experienced at least one earthquake, they seemed to favor two days of the week, in particular. Earthquakes occurred on Tuesday and Wednesday as much as 60% more often than on other days of the week.
