Understanding Earthquakes
The magnitude of an earthquake indicates the energy released at its source. The U.S. Geological Survey has updated its measurement system, replacing the Richter scale. Tremors between 2.5 and 5.4 in magnitude are typically felt but cause minimal damage. Earthquakes below 2.5 are usually unnoticed by the populace.
- Estimated global earthquakes each year: 500,000
- Detectable quakes that can be felt: 100,000
- Quakes causing damage annually: 100
Precautionary Measures During an Earthquake
In the event of an earthquake, it’s crucial to know how to protect yourself effectively. Here are recommended actions based on your location:
- If in a car: Pull over, stop, and set your parking brake.
- If in bed: Turn face-down and cover your head with a pillow.
- If outdoors: Stay away from buildings and avoid going inside.
- If indoors: Remain inside, avoid doorways, and stay put.
The safest strategy during an earthquake is to “Drop, Cover, and Hold On.” This involves getting down on your hands and knees and securing yourself beneath a sturdy object, if available. Protect your head and neck with your arms and be prepared for movement if the shelter shifts.
Post-earthquake hazards can include damages such as leaking gas or downed power lines. Aftershocks frequently accompany the initial tremor, so it’s vital to remain vigilant and ready to respond again.
For those who felt the earthquake, sharing experiences can be done through the USGS Felt Report form. Awareness and preparation are key to safety in earthquake-prone areas like California.
