I'm over in Huntington Beach for a fortnight at the end of the month. I have only ever experienced one quake over there and that was around a 3 at sparrow fart and I was still in bed just thinking about getting up to make coffee. The 3 rattled a few things but did no damage.Just spoke with both of my parents, and they are fine based on where they live..
One hates to be pedantic, but...The US Navy was surveying for damage on Naval Weapons Station China Lake which is in the area. A large base (1,100,000 acres, 1700+ square miles) they have to be careful as there is often unexploded ordinance on the ranges. The Navy is usually careful around unexploded ordinance.
