Understanding Earthquakes: A Primer

What is an Earthquake?

An earthquake, also known as a seismic event or tremor, occurs when the earth's crust suddenly releases energy. This energy manifests as vibrations that travel through the ground, creating seismic waves.

Causes of Earthquakes

Earthquakes are primarily caused by the movement of tectonic plates, large slabs of rock that make up the earth's crust. When plates collide, slide past each other, or pull apart, it can generate immense stress, leading to earthquakes.

Other factors that can contribute to earthquakes include volcanic activity, meteorite impacts, and human-induced events such as explosions or fracking.

Measuring Earthquakes: Magnitude and Intensity

Magnitude

The magnitude of an earthquake is a measure of the energy released during the event. It is determined using seismographs, instruments that record ground motion. The magnitude scale is logarithmic, meaning each whole number increase represents a tenfold increase in energy.

Intensity

Intensity, on the other hand, describes the severity of ground shaking experienced at a particular location. It is based on observed effects such as damage to structures, ground deformation, and eyewitness accounts. Intensity is represented using the Modified Mercalli Intensity Scale (MMI), which ranges from I (not felt) to XII (catastrophic).

Earthquake Preparedness: Staying Safe During Tremors

Before an Earthquake

To ensure safety during an earthquake, it is crucial to be prepared beforehand. This includes having an emergency plan, assembling an emergency kit, and securing heavy objects in the home.

It is also essential to know the earthquake risks in your area and identify safe evacuation routes.

During an Earthquake

If you experience an earthquake, the most important thing is to remain calm and take immediate action. Drop to the ground, take cover under a sturdy table or desk, and hold on until the shaking stops.

Stay away from windows, outside doors, and heavy objects that could fall.

After an Earthquake

Following an earthquake, it is important to check for injuries and damage to yourself and others. Be cautious of aftershocks, which can occur for hours or even days after the main event.

If you suspect damage to your home or property, contact a professional for inspection.
