Another notable source of activity was the Parkfield area, at the top of this image, near the northwest corner. The largest earthquake there was of magnitude 4.6, on the 14th of November. The aftershock sequence of this earthquake dominates the seismicity of the Los Angeles area. Well to the east of Los Angeles, Landers aftershocks persist with remarkable strength. Of new interest in this animation is the start of the Ridgecrest sequence , which begins with a magnitude 5.4 event on August 17th, and peaks with a magnitude 5.8 event on September 20th.
Ridgecrest aftershocks persist throughout the rest of the year.
