Earthquake - Good News/Bad News!

The headline that got my attention in today's Times is "The Dual Threats of Seismic Activity and Rising Seas."  A big picture of the San Francisco waterfront accompanied the article, so there was no chance I'd pass it by.

Experts say there is a 72% chance of at least a magnitude 6.7 earthquake occurring here before 2043.  For reference, the Loma Prieta earthquake in 1989 was 6.9, and the epicenter was 60 miles away.  They point out we might not be so lucky next time.

I didn't know that our waterfront is held in place by a 19th century underwater sea wall that is already sinking into the bay and is being weakened by the rising sea,  Add an earthquake to the mix and the whole thing can slide into San Francisco Bay.

The good news is that the predicted quake hasn't happened yet.  The bad news is that it will.

Have a good day!
