Understanding Earthquake Magnitudes
The magnitude of an earthquake measures the energy released at its source. The old Richter scale has been replaced by new methods of measurement. Earthquakes ranging from 2.5 to 5.4 are often felt but typically don’t cause significant damage. Those below 2.5 are generally not felt by most individuals.
According to estimates from the Department of Homeland Security, around 500,000 detectable earthquakes occur globally each year. Out of these, roughly 100,000 can be felt, with around 100 resulting in damage.
Earthquake Safety Tips
In the event of an earthquake, it is crucial to take immediate action to protect yourself. Here are some expert-recommended steps:
- In a car: Pull over and stop. Activate your parking brake.
- In bed: Lie face down and use a pillow to shield your head.
- Outdoors: Move away from buildings and do not re-enter.
- Indoors: Remain where you are and avoid running outside. Stay clear of doorways.
The fundamental approach to safety during an earthquake is to “drop, cover, and hold on.” This involves getting down on your hands and knees and taking cover under something sturdy, like a table, while holding on until the shaking stops.
Individuals with mobility aids should ensure they are secured and remain in their seats during the event. Aftershocks may follow the initial quake, so staying alert and ready to respond is important.
Potential hazards after an earthquake can include damage to buildings, gas leaks, and downed power lines. Remaining vigilant following the main shock is essential for personal safety.
