Southern Los Angeles was treated to a rude awakening with three quakes within the space of half an hour, with thousands of people reporting shaking beds and even cracking walls.
A preliminary 3.3 magnitude quake struck first, some 12 miles below the surface, followed by a smaller one just a minute later. These, it seems, were precursors of the noticeably more significant 4.0 magnitude quake also 12 miles below the surface, at the bizarrely triple-digit time of 4:44 am according to the U.S. Geological Survey (USGS).

The town of Englewood, pop. 111,700 was just one mile from the epicenter, with Los Angeles (pop. 4 million) was a mere nine miles away. Our monitoring service received almost 2000 records from concerned users of our website and app, with comments ranging from "a personal thunderstorm in my bedroom" and "walls creaking" to "felt like a sonic boom" and "sounded like a bomb."

It was obvious from the feedback that the quake was a rough one, yet luckily, we did not get any reports of injuries or serious damage.

Earthquake expert Dr. Lucy Jones informed Fox news that the quake did not occur on any mapped fault. Unlike European and other earthquake experts, Jones called this event a "very deep" earthquake even though it was only 12 miles below ground, which would be considered shallow by other global seismology academics and institutes.
The discrepancy lies perhaps in the fact that numerous quakes in the US tend to be on the shallow side compared to Europe, Africa and Asia. It is worth noting that sometimes in the US, there is talk of human intervention and speculation associated with quakes (e.g. fracking, carbon capture, gas exploration), although none of these were reported in connection with this incident.
VolcanoDiscovery continues to monitor the situation and will update if more developments occur in connection to the 4-magnitude quake at 4:44 am.
