A minor earthquake measuring 3.8 on the Richter scale occurred in the San Francisco Bay Area. This seismic event was recorded on Sunday morning by the United States Geological Survey (U.S.G.S.). The quake struck at 9:38 a.m. PT, approximately two miles southeast of San Ramon, California.
Details of the Earthquake
The initial magnitude was reported as 3.7 but was later upgraded to 3.8 after additional analysis. As seismologists continue to study the data, further revisions to the earthquake’s magnitude may be forthcoming.
Aftershocks in the San Francisco Bay Area
Following the initial quake, aftershocks were also reported in the region. An aftershock is typically a smaller quake that follows a larger seismic event, as adjustments occur along the fault line involved.
- Aftershocks can occur days, weeks, or even years after the main quake.
- These smaller tremors can sometimes match or exceed the magnitude of the original earthquake.
- They pose a risk to already affected areas, maintaining concern among residents and authorities.
Seismic Activity Monitoring
The U.S.G.S. utilizes the Modified Mercalli Intensity scale to categorize shaking experiences. Data collected from aftershocks and subsequent quakes may influence the shake-severity maps available to the public.
For updated information on seismic activities and aftershock occurrences, residents and interested parties can access details from the U.S.G.S., ensuring safety and preparedness in affected areas.
