The U.S. Geological Survey says a 4.9 earthquake struck the northern Baja California region of Mexico near the U.S. border today. It's the latest in a series of quakes to shake Northern Baja. And a San Diego geologist says that area will continue to shake. More from KPBS reporter Ed Joyce.
The USGS says the quake was centered about 20 miles southeast of the border town of Mexicali. The epicenter was 23 miles southeast of the U.S. city of Calexico. San Diego State University Professor Emeritus of Geology Pat Abbott says the earthquake faults are opening the Gulf of California by pulling away San Diego and Baja California.
Abbott: So you can kind of visualize Mexico sitting there and Baja California, San Diego, Los Angeles pulling away to the northwest and leaving mainland Mexico behind and an opening ocean basin between them.
Abbott says more aftershocks and earthquakes will follow since the region is one of the most active in the world.
The latest quake comes three days after the Mexicali area was rocked by a 5.4 quake that shut down factories and left 400,000 people without power. Officials say there was no damage on the U.S. side of the border from today's quake. Ed Joyce, KPBS News.
