Back-to-back magnitude-4.5 and -3.4 earthquakes were reported Wednesday morning near Yorba Linda area, just hours after a magnitude-4.4 quake and several aftershocks were reported in the area.Wednesday's earthquake was reported at 9:33 a.m. about one mile northeast of Yorba Linda. A magnitude-3.4 quake was reported at 9:51 a.m. in the same area."It's hard to tell if this was a quake or aftershock because they were in the same area and same magnitude, so I would call this a double-quake," said Dr. Kate Hutton, staff seismologist at Caltech. "I would call this a cluster or quake swarm. We can expect to see more small quakes-aftershocks."
