A huge earthquake shook the ocean floor off the coast of Indonesia Wednesday. Early measurements by the U.S. Geological Survey give it a strength of 8.7. Surrounding nations have issued tsunami warnings.
For those who just felt the earth shake in Northern California, the U.S. Geological Survey says there was a 4.0 magnitude temblor in the "San Francisco bay area" at 5:33 a.m. local time (8:33 a.m. ET).
There's no word yet on whether there was much, if any, damage.
The USGS says the quake was centered about 1 mile from El Cerrito, Calif.
