Understanding Earthquake Magnitude

The magnitude of an earthquake indicates the energy released. The U.S. Geological Survey now uses a modern scale that has replaced the older Richter scale. Tremors measuring between 2.5 and 5.4 are typically felt but seldom cause significant damage. Those under 2.5 are often undetectable by the general public.

Global Earthquake Statistics

• An estimated 500,000 detectable earthquakes occur worldwide annually.
• Of these, approximately 100,000 can be felt.
• Only about 100 earthquakes result in damage each year.

Safety Tips During an Earthquake

When an earthquake occurs, immediate action is crucial for safety. Here are essential guidelines:

• In a Car: Pull over, stop, and set the parking brake.
• In Bed: Lie face-down and use a pillow to protect your head.
• Outdoors: Stay clear of buildings and other structures.
• Indoors: Remain inside, avoid doorways, and find cover under a sturdy table.

Officials advise adopting the “Drop, Cover, and Hold On” technique for optimal protection. If you’re in a wheelchair or walker, ensure the wheels are locked and stay seated until the shaking stops.

Post-Earthquake Hazards

After an earthquake, be prepared for potential risks such as building damage, leaking gas, or downed power lines. Expect aftershocks, and be ready to drop, cover, and hold on if they occur.

For those who felt the recent earthquake, a report can be submitted to the U.S. Geological Survey using their Felt Report form.
