The series of moderate earthquakes -- including several magnitude 5.0 and above -- were felt as far north as Orange County, east into Arizona and south into Mexico, according to the U.S. Geological Survey.
The USGS recorded more than two dozen earthquakes in Imperial County, many of them near Brawley. Officials said people reported feeling the quake in Yuma, Ariz., Lake Havasu as well as in Baja California.The burst of quakes took place roughly 16 miles from El Centro and 92 miles from Tijuana. In the last 10 days, there have been six earthquakes of magnitude 3.0 or greater centered nearby.Here is a preliminary magnitude count of some of the quakes Sunday:

On August 24th, we warned on Forbes that Tropical Storm Isaac could pose a threat to energy markets and even rival Hurricane Katrina in its destructive power (Could Tropical Storm Isaac Turn Into Another Katrina?). While the computer models are still showing a substantial spread in solutions, it appears more likely that Isaac will make landfall somewhere near the Louisiana, Mississippi Gulf Coast. This track will provide the storm more time to intensify over the very warm water of the Gulf of Mexico.
Tropical Storm Isaac lashed south Florida with winds and heavy rain on Sunday after battering the Caribbean, disrupting plans for the Republican National Convention in Tampa and threatening to interrupt about half of U.S. offshore oil output.
Isaac was due to be at or near hurricane strength soon after its center crosses the Florida Keys late on Sunday. A storm becomes a hurricane when sustained winds reach a minimum of 74 miles per hour (119 kph).
The NHC said Isaac was expected to intensify to a Category 2 hurricane, with "extremely dangerous" sustained winds of 105 miles per hour (169 kph), as it swept up the warm waters of the Gulf of Mexico.
At 2 p.m. EDT (1800 GMT) on Sunday, Isaac was about 50 miles (85 km) south-southeast of Key West and packing top sustained winds of 60 miles (100 km) per hour.Isaac is expected to strengthen to a Category 2 hurricane and hit the Gulf Coast somewhere between Florida and Louisiana at midweek - on or near the seventh anniversary of Hurricane Katrina - the U.S. National Hurricane Center (NHC) said in an advisory.
With Iran as with Syria, however, the Americans are urging that more time be given to diplomacy, and the Israelis are stressing the urgent imperative for action.
