A mild shaking was felt by some residents of the Pine Mountain community on Friday, March 28 at about 9:10 p.m. That corresponds with the timing of a 5.1 magnitude earthquake that struck 1 mile east of La Habra and southeast of Los Angeles at 9:09 p.m.

The La Habra quake occurred at a depth of 1.2 miles, according to reports by the United States Geological Survey. It was followed by a 3.4 magnitude quake just two minutes later in the same area, but nearer the surface, at a depth of only .1 mile. That area is on the Puente Hills Fault. It was a reminder of the need here to develop a family earthquake preparedness plan. —P. Hedlund
