San Bernardino Shaken by Preliminary 4.2-Magnitude Earthquake

0

A preliminary 4.2-magnitude earthquake sent tremors through San Bernardino on Wednesday evening, as reported by the United States Geological Survey (USGS).

The seismic event occurred at precisely 7:43 p.m., centered approximately 1.864 miles southwest of San Bernardino. Fortunately, there were no immediate reports of injuries or structural damage resulting from the quake.

Dr. Allen Husker, a seismologist from CalTech’s Seismological Laboratory, commented on the earthquake, noting its proximity to the surface and the densely populated nature of the region. “It was close to the surface but also in a populated region, so San Bernardino County has plenty of people, so they’re going to feel it, definitely,” said Dr. Husker.

The effects of the earthquake were not confined to the epicenter, as residents in surrounding areas such as Burbank, Santa Fe Springs, Chino, Fontana, and more reported feeling the jolt. The widespread impact underscores the significance of the seismic activity in the region.

One resident, Timothy Key, was recording a video at the time of the earthquake and managed to capture the moment when his home was shaken by the tremors. This firsthand account provides a glimpse into the intensity of the seismic activity experienced by residents in the affected areas.

As seismic experts and local authorities continue to assess the aftermath, residents are urged to remain vigilant and prepared for potential aftershocks. The event serves as a reminder of the importance of earthquake preparedness in earthquake-prone regions like Southern California.

Is a magnitude of 4.2 considered a strong earthquake?

Answer:

The strength of an earthquake is influenced by various factors, including your proximity to the epicenter, the type of soil in the area, building construction, and more. Generally, a magnitude of 4.2 is considered moderate. However, the potential for damage is typically lower at this level. Significant damage typically occurs when the magnitude surpasses 4 or 5. It’s essential to stay informed about earthquake preparedness and follow safety guidelines regardless of the magnitude, especially in regions prone to seismic activity.

What size earthquake is bad?

Earthquake Magnitude Scale:

  • Magnitude 5.5 to 6.0: Slight damage to buildings and other structures may occur.
  • Magnitude 6.1 to 6.9: This range has the potential to cause a lot of damage, especially in densely populated areas. Significant structural damage may be observed.
  • Magnitude 7.0 to 7.9: Considered a major earthquake, this magnitude can result in serious damage. It has the potential to cause widespread destruction to buildings, infrastructure, and communities.
  • Magnitude 8.0 or greater: A magnitude of 8.0 or higher is classified as a great earthquake. These events can be catastrophic, with the ability to totally destroy communities near the epicenter. The impact can extend over a large geographic area, leading to severe and long-lasting consequences.

It’s crucial for individuals and communities to be well-prepared and informed about earthquake safety measures, regardless of the magnitude. Following established guidelines and having emergency plans in place can significantly mitigate the risks associated with seismic events.
