A 4.0-magnitude earthquake near Ontario, California, shook the Los Angeles area early on October 6, prompting nearly 6,000 reports from residents feeling the tremor. The U.S. Geological Survey clarifies the magnitude scale and highlights the importance of proper safety protocols during an earthquake.
On Sunday, October 6, a 4.0-magnitude earthquake struck near Ontario, California, jolting the Los Angeles area. According to the United States Geological Survey (USGS), the quake occurred at a depth of three miles at precisely 3:51 a.m., approximately three miles from Ontario. By midday, close to 6,000 individuals from locations as distant as Oakley and Paso Robles had reported sensations of the tremor to the agency. Public reactions varied, with social media comments expressing surprise and indifference; one individual remarked, “That’s another big earthquake for me,” while another stated, “I must’ve been knocked out! I didn’t feel a thing.” One commenter noted it was “a little stronger than the last one in a series over the past few weeks.” In terms of seismic measurement, the USGS explains that magnitude quantifies the energy released at the quake’s source, superseding the older Richter scale. Generally, earthquakes within the magnitude range of 2.5 to 5.4 are perceivable to people but tend to inflict minimal damage. Those measuring below 2.5 are often unnoticed by the majority. Earthquakes can give rise to various devastating consequences, including fires, tsunamis, landslides, or avalanches. The likelihood of earthquakes is especially pronounced in regions such as Alaska, California, Hawaii, Oregon, Puerto Rico, and Washington, as indicated by the Department of Homeland Security. To protect oneself during an earthquake, experts recommend immediate action. Individuals in cars should pull over and cease movement while setting their parking brake. Those in bed should turn face-down and shield their heads with a pillow. For those outdoors, staying away from buildings is advised. Conversely, individuals inside should remain put, avoiding doorways and not rushing outside. The fundamental action is to “drop, cover, and hold on.” Authorities emphasize, “Wherever you are, drop down to your hands and knees and hold onto something sturdy.” If a sturdy table is not available, it is suggested to crawl to an interior wall, away from windows, and protect the head and neck with the arms. After securing oneself under shelter, individuals should hold on with one hand and be prepared to move with the shelter. Officials caution that significant dangers can arise after an earthquake, including structural damage, gas and water line ruptures, and downed power lines. They advise individuals to brace for possible aftershocks that may succeed the main earthquake and to be ready to execute the “Drop, Cover, and Hold On” protocol upon feeling any aftershocks.
The occurrence of earthquakes, a natural phenomenon caused by the sudden release of energy in the Earth’s crust, poses significant risks, particularly in seismically active regions like California. The state is subject to frequent seismic activity due to its location along the Pacific Ring of Fire, where tectonic plates intersect. Given these environmental conditions, it is pertinent for citizens and authorities alike to remain informed and prepared for potential seismic events. Understanding earthquake magnitudes and recommended safety protocols is crucial for minimizing harm during such incidents.
In summary, the recent 4.0-magnitude earthquake near Ontario, California, which affected a wide area, serves as a reminder of the seismic risks faced by residents in active regions. Individuals are encouraged to familiarize themselves with safety measures and proper responses during such events to ensure their safety and preparedness for future tremors.
