According to the U.S. Geological Survey, two small earthquakes shook the vicinity of Ontario, California, causing minor shaking for Southland residents who are already dealing with a scorching heat wave. The first quake, initially classified as a foreshock, occurred at 10:05 a.m. and measured a magnitude of 3.5. It was centered around 4.3 miles southeast of Ontario. This was followed by a 3.9 earthquake at 10:34 a.m., with its epicenter located about 4.4 miles southeast of Ontario and 4.7 miles northwest of Jurupa Valley in Riverside County.

Approximately an hour later, at 11:45 a.m., a 2.6 magnitude aftershock was felt around two miles southeast of Ontario, according to a report from ABC 7. Fortunately, no damage has been reported in the wake of these seismic events.

As news of the quakes spread, locals took to social media to share their experiences and reactions. Dubbed "Earthquake Twitter," users flooded platforms with a variety of posts, including memes and videos capturing the tremors. The account @QuakesInCA, which relies on USGS data, highlighted several aftershocks that occurred within five miles of Ontario, most of them ranging from magnitudes of 2.0.

Renowned seismologist Dr. Lucy Jones, who appeared as a guest on John Mulaney Presents: Everybody's In LA Emmy-submitted earthquake episode, offered insights into the recent quakes. She stated, "Today we are having a small swarm in the Fontana Seismicity Lineation, a northeast-striking line of many small quakes. Today we have so far recorded a 3.9, 3.5, and several smaller magnitudes including 1s and 2s. I have observed similar clusters in Fontana numerous times throughout my years of monitoring earthquakes in Southern California."

Although Los Angeles has experienced a series of earthquakes this summer, Dr. Jones debunked the widely believed notion of "earthquake weather." She emphasized, "Today's quakes are just a few among many that have occurred throughout the year, most of which took place during periods of normal weather, contrary to popular belief."

As residents continue to monitor the seismic activity, experts emphasize the importance of remaining prepared and informed about earthquake safety measures.
