Mexicali Baja earthquake caused minor damage to CAL FIRE Facilities

7.2 was the strongest recorded quake in modern times.
Mexicali Baja earthquake caused minor damage to CAL FIRE Facilities

Major damage in Mexicali; minor damage to some East County facilities
5% chance of even bigger quake in next few days - Cal Tech

Twenty million people in three U.S. states and Mexico felt Sunday's Baja California earthquake — a more powerful temblor than the Haiti quake yet the death toll and devastation were far less.
Why? Scientists say part of the answer is location, location, location.

Only about 500 people in the agricultural communities south of the growing city of Mexicali were exposed to the most violent shaking.

USGS: No 4.0 Earthquakes quakes hit Northern California on Sunday

Northern California USGS quake reports/deletions: Seismologist Susan Potter says all Nor Cal quake reports larger than 2.3 today are false. No 4.0 Earthquakes quakes hit Northern California on Sunday, earlier reports were wrong.
 
It was not immediately clear why the false reports were generated, but large temblors can often produce faulty readings in distant areas.
