The earthquake in Southern Mexico Friday morning has scientists watching faults in California.
The Acapulco quake begs the question: Is there a connection between the cause of that shaker and possible quakes from LA to the Bay Area?
"Well, there's a debate about that going on," John Rundle, a geology professor at U.C. Davis, said.
"To some extent, the answer to your question is, it's connected, but we don't really know how," he said.
All of the faults are a part of the boundary of the Pacific Plate, he said.
Professor Rundle says he's thinks it's unlikely the Mexico quake will trigger one here, but predicts with online tools there's a 66 percent chance this could be followed by another quake within a 100 miles of Acapulco in the next three years.
