Google Public Alerts to Provide Severe Weather Warnings
If you're traveling to Texas this week, you probably want to know that there's some severe weather going on in the Lone Star State, and starting today, Google will provide you with that information through a new dedicated site.

On Monday morning this week, a wide swath of southern California–from L.A. to Needles to Calexico–was gently jolted by a modest M4.7 earthquake from the San Jacinto fault.
