Earthquake

An earthquake is the shaking of the surface of the Earth resulting from a sudden release of energy.

How it works?

It happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane. The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter.

2 Earthquake cases

The April 2015 Nepal earthquake killed nearly 9,000 people and injured nearly 22,000. It occurred on 25 April 2015.

It was the worst natural disaster to strike Nepal since the 1934 Nepal–Bihar earthquake. The ground motion recorded in the capital of Nepal was of low frequency, which, along with its occurrence at an hour where many people in rural areas were working outdoors, decreased the loss of property and human lives.

In the 27 March 1964 Alaskan earthquake, for example, strong ground shaking lasted for as much as 7 minutes.

Earthquake results

Buildings can be damaged or destroyed, people and animals have trouble standing up or moving around, and objects can be tossed around due to strong ground shaking in earthquakes, many people are killed in earthquakes.

Self-defense instructions during an earthquake

Take some time to discuss evacuation with your family. Sketch a floor plan of your home; walk through each room and discuss evacuation details.
Plan a second way to exit each room or area. If special equipment is needed, mark where it is located.
Mark where your emergency food, water, first aid kits, and fire extinguishers are located.
Store a type-ABC fire extinguisher in an easily accessible location.
Mark where the utility switches or valves are located, and learn how to turn off your gas and water mains, as well as electricity.
Indicate the location of your family’s emergency outdoor meeting place.
Keep several flashlights in easily accessible places around the house.

Self-Defense Instructions During an Earthquake (Continued)

Keep a wrench or turn-off tool in waterproof wrap near the gas meter.
Know whether you live, work or play in a tsunami hazard zone.
Obtain a NOAA Weather Radio with the Public Alert feature to notify you of tsunamis and other hazards.
Keep a flashlight, slippers and gloves next to beds.
Keep your gas tank at least half full.
Determine safe spaces away from windows in each room of your home. Choose spots where it is unlikely something will fall on you.
Prepare a disaster kit. Stock up on canned food, a first-aid kit, 3 gallons of water per person, dust masks, goggles, battery-operated radio and flashlights.
