The first main shock (now deemed to be a <a href="/wiki/Foreshock" title="Foreshock">foreshock</a>) occurred on Thursday, July 4 at 10:33 a.m. <a href="/wiki/Pacific_time_zone" class="mw-redirect" title="Pacific time zone">PDT</a>, approximately 18 km (11.2 mi) ENE of Ridgecrest, and 13 km (8.1 mi) WSW of <a href="/wiki/Trona,_San_Bernardino_County,_California" title="Trona, San Bernardino County, California">Trona</a>,<a href="#cite_note-9">[9]</a> on a previously unnoticed NE-SW trending fault where it intersects the NW-SE trending Little Lake Fault Zone.<a href="#cite_note-10">[10]</a> This quake was preceded by several smaller earthquakes, and was followed by more than 1,400 detected aftershocks.

While the actual shaking reached intensity 4 in some areas in the northern part of the county, in other parts the intensity reached only a level 2 or 3, not noticed by many people.<a href="#cite_note-86">[86]</a> The second quake, having a greater magnitude, was felt more strongly, with an intensity of 4.5 in some places, and 3.9 downtown.<a href="#cite_note-87">[87]</a> According to the City of Los Angeles's Twitter account, the threshold will be lowered after this event.<a href="#cite_note-88">[88]</a><a href="#cite_note-89">[89]</a> <div class="mw-heading mw-heading2"><h2 id="Tectonic_setting">Tectonic setting</h2>[<a href="/w/index.php?title=2019_Ridgecrest_earthquakes&action=edit&section=10" title="Edit section: Tectonic setting">edit</a>]</div> <figure typeof="mw:File/Thumb"><a href="/wiki/File:UCERF3_fig01-b.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/9/98/UCERF3_fig01-b.jpg/500px-UCERF3_fig01-b.jpg" decoding="async" width="500" height="357" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/9/98/UCERF3_fig01-b.jpg/750px-UCERF3_fig01-b.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/9/98/UCERF3_fig01-b.jpg/1000px-UCERF3_fig01-b.jpg 2x" data-file-width="2088" data-file-height="1492" /></a><figcaption> Red marks the major fault zones.
