FAQs About Earthquakes
What causes earthquakes?
Earthquakes are primarily caused by the movement of tectonic plates beneath the Earth’s surface. When these plates shift and rub against each other, they release energy that causes the ground to shake.
How can I determine the magnitude of an earthquake?
The magnitude of an earthquake is measured using a seismograph and is indexed on a logarithmic scale, where small increases in magnitude correspond to vastly more powerful earthquakes.
What should I do during an earthquake?
During an earthquake, drop to your hands and knees, cover your head and neck under sturdy furniture, and hold on until the shaking stops. Stay indoors and do not rush outside, as falling debris poses a significant risk.
How can I stay informed about seismic activity?
Monitor local geological services, news outlets, and mobile apps specifically designed to report on seismic activity for the latest updates and safety information.
