M7.3 - Alaska, 1958One of the Largest Earthquakes in the United States.
Felt over a wide area of central Alaska. There was evidence of pressure ridges, lakes thawing, and craters 6 meters across and about 2 meters deep

this is the plate tectonic that starts earthquakes

# data[].attributes.body
The plates consist of an outer layer of the Earth, the lithosphere, which is cool enough to behave as a more or less rigid shell. Occasionally the hot asthenosphere of the Earth finds a weak place in the lithosphere to rise buoyantly as a plume, or hotspot. The satellite image below shows the volcanic islands of the Galapagos hotspot.

Aftershock: a smaller earthquake that occurs after a larger earthquake.

Compression: a type of stress that squeezes rock, causing it to break or fold.

Earthquake: movement of the ground caused by the release of energy from a sudden shift of rocks in Earth's crust.

Epicenter: the point on Earth's surface directly above the focus of an earthquake.

Fault: a break in Earth's crust where movement of rock occurs.

Fault zone: a place along plate boundaries where many faults are located.

Focus: the point below Earth's surface where movement of rock produces an earthquake.

what this earthquake did was the tectonic plates moved in the opposite direction of where the road originally occurred .where the focus is that's what caused the earthquake

# data[].attributes.body
Earth's crust is composed of many huge, rocky plates known as tectonic plates.These plates constantly move slowly across the surface of Earth, bumping into each other, overrunning each other, and pulling away from each other.When the strain produced by these movements increases beyond a certain level, the pent-up energy ruptures the crust and creates a fracture known as a fault. The released pressure also causes the ground-shaking vibrations associated with an earthquake.

P (Primary) wave: the fastest moving type of seismic wave, which expands and compresses rock, like the movement of a slinky. Also known as pressure waves. P waves can travel through both liquids and solids.

Reverse fault: a type of fault where compression pushes rock together. Also known as a thrust fault.

Richter scale: a measurement of the magnitude of an earthquake based on the readings of a seismograph. The Richter scale is a logarithmic scale ranging from 0 to 9, with each number representing a 10-fold increase in ground motion, and a 30-fold increase in energy released.

S (Secondary) wave: the second-fastest moving type of seismic wave, which moves rock horizontally from side to side. Also known as shear waves. S waves cannot pass through liquids, and therefore cannot pass through Earth's liquid outer core.

Seismic wave: a vibration that travels through Earth carrying the energy released during an earthquake.

Seismograph: an instrument that records seismic waves.

Shearing: a type of stress that pushes two adjacent areas of rock in opposite directions.

Foreshock: a small earthquake that precedes a larger earthquake.

Magnitude: the measurement of the total strength or amount of energy released by an earthquake.

Mercalli scale: a measurement of an earthquake's intensity based on how much damage it causes. The Mercalli scale ranges from Level I (not felt except by very few under favorable conditions) to Level XII, (causing almost total destruction.)

Moment magnitude scale: a measurement of an earthquake's magnitude based on the amount of movement of the rock along a fault line.

Normal fault: a type of fault where forces of tension are pulling rock apart.

Stress: a force that causes rock to change shape.

Strike-slip fault: a type of fault where rocks slide horizontally past each other in opposite directions, with little up or down motion. The San Andreas fault in California and the North Anatolian fault in Turkey are examples of strike-slip faults.

Surface waves: seismic waves that move along Earth's surface. They can have an up-and-down motion or a horizontal motion. Surface waves travel slower than P or S waves and usually cause the most damage.

Tension: a type of stress that stretches rock and makes it thinner.

Tsunami: a giant, fast-moving wave that is caused by an undersea earthquake. Also known as a seismic sea wave

Earthquakes kill approximately 8,000 people each year and have

caused an estimated 13 million deaths in the past 4,000 years.

An average earthquake lasts around a minute.

More earthquakes happen in the Northern Hemisphere than in the Southern

Hemisphere.

The world’s worst landslide started by an earthquake occurred in 1920

in the Kansu province in China. The landslide killed about 200,000 people

Natural events such as volcanic eruptions and meteor impacts can cause earthquakes, but the majority of naturally-occurring earthquakes are triggered by movement of the earth's plates.

An earthquake is an unpredictable event in which masses of rock shift below earth's surface,

releasing enormous amounts of energy and sending out shock waves that sometimes

cause the ground to shake dramatically. Not all earthquakes are enormous

, but they can become one of Earth's most destructive forces.
