According to the Oxford Dictionary, an Earthquake is defined as a sudden and violent shaking of the ground, sometimes causing great destruction, as a result of movements within the earth’s crust or volcanic action.
Some other names for an Earthquake include tremor, convulsion, quake, shake, and trembler!
The most common type of Earthquake is the tectonic earthquake. These happen when movement of tectonic plates create geological forces. The forces will cause the rocks in the earth’s crust to break.
The second most common type of Earthquake is the volcanic earthquake. This is caused by the movement of magma in a volcano.
Collapse Earthquakes are small earthquakes underground that are caused by elastic (seismic) waves that occur due to an explosion of rocks on the surface.
Explosion Earthquakes are caused by the detonation of chemicals and/or nuclear devices.
The best way to know that an earthquake is taking place is when the ground shakes. If an earthquake is happening from far away, you may feel a gentle bump on the ground, possibly followed by more rolling shaking later on. A close earthquake will feel like a sharp jolt, followed by faster, stronger jolts.
There are many signs that an Earthquake could be imminent! Knowing these signs can help you to be prepared and can also help you guide your loved ones, yourself, and/or pets to safety before an Earthquake actually occurs.
Notice smaller earthquakes that lead up to the main earthquake! If you feel like the ground may be rumbling or shaking, take all precautions to keep your family and yourself safe! If you think you feel the ground moving, move to safety! It is better safe than sorry!
If you have any type of shelter available (ex: table, counter, any hard surface you can climb under) immediately get underneath! You should be on your knees with your hands protecting your head and neck! Your neck has all of the nerves leading from your brain to your body. Any nerves being damaged can lead to permanent damage. If you do not have access to a hard surface that you can climb under, get as close to an interior wall as you possibly can! Do not hesitate! This is crucial!
It never hurts to have a prepared kit for any weather related issues!!! Some items you may want to keep put in an emergency bag in case of an Earthquake are:
- First-Aid Kit
- Weather Radio
- At Least 3 Gallons of Water Per Person
- Non-perishable food items-to be able to eat! Have enough for a minimum of 3 days! If you have pets, keep pet food aside as well! If you are using cans, be sure to have a can opener.
- Tools-in case you get stuck somewhere. I recommend a hammer or something strong in case you need to beat yourself out of an entrapment.
