Experts say April's 7.2 quake put more pressure on the San Jacinto fault, triggering the 5.4-magnitude temblor that shook much of Southern California on Wednesday. It rattled nerves but caused no major damage. The moderate 5.4 magnitude earthquake that rolled through Southern California on Wednesday was probably triggered by the Mexicali temblor that hit Easter Sunday, seismologists said.
