The greater Los Angeles area has experienced a few mild earthquakes over the past 18 hour period, centered in the city of Yorba Linda, just north of Orange and Santa Ana–southeast of L.A. proper. The surrounding cities in Orange County and throughout the San Gabriel valley were abuzz with “the feeling,” yet few felt effects, even as close as Hollywood an into the San Fernando Valley.
The first hit at 11:32pm on Tuesday night, though I swore I felt something earlier while shopping at IKEA. Perhaps it was just the influx of college students thundering through the facility looking for dorm furniture. That considered as possibility, several aftershocks have pushed throughout the area, ranging in size from 1.2 – 2.2. Early Wednesday, a couple more rumblers, one touching 4.1 on the Richter scale, centered around the same area.
These quakes are resultant of the rub of the shallows, unlike the activity that is often recorded along the Pacific Ring of fire. Such subduction zones have also recorded activity over the last 24 hours–and these are the quakes that possess potential comparability to what we saw in Japan just over a year ago. The Juan de Fuca subduction zone is located along the Oregon and Washington coasts, and a significant shake is considering long overdue.
