If the earthquake occurs in the ocean, it can push up powerful waves, known as tsunamis. The sudden upward or downward movement of the seafloor during an earthquake creates large tsunami waves, Earthquakes can also trigger tsunamis by unleashing underwater landslides, which also displace huge amounts of seawater. Most tsunamis–about 80 %–happen within the Pacific Ocean. “The Ring of Fire,” is  geologically active area where tectonic shifts make volcanoes and earthquakes common. Tsunamis race across the sea at up to 805 kilometres an hour -about as fast as a jet airplane Thats fast. At that pace, they can cross the entire expanse of the Pacific Ocean in less than a day.
Great research, Ben. I wouldn't want to be in that little car when the wave hit!

An earthquake is an intense shaking of Earth’s surface. The shaking is caused by movements in Earth’s outermost layer.
Why Do Earthquakes Happen?
Although the Earth looks like a pretty solid place from the surface, it’s actually extremely active just below the surface. The Earth is made of four basic layers: a solid crust, a hot, nearly solid mantle, a liquid outer core and a solid inner core.

The solid crust and top, stiff layer of the mantle make up a region called the lithosphere. The lithosphere isn’t a continuous piece that wraps around the whole Earth like an eggshell. It’s actually made up of giant puzzle pieces called tectonic plates. Tectonic plates are constantly shifting as they drift around on the viscous, or slowly flowing, mantle layer below.

This non-stop movement causes stress on Earth’s crust. When the stresses get too large, it leads to cracks called faults. When tectonic plates move, it also causes movements at the faults. An earthquake is the sudden movement of Earth’s crust at a fault line.

The location where an earthquake begins is called the epicenter. An earthquake’s most intense shaking is often felt near the epicenter. However, the vibrations from an earthquake can still be felt and detected hundreds, or even thousands of miles away from the epicenter.
How Do We Measure Earthquakes?
The energy from an earthquake travels through Earth in vibrations called seismic waves. Scientists can measure these seismic waves on instruments called seismometer. A seismometer detects seismic waves below the instrument and records them as a series of zig-zags.
Scientists can determine the time, location and intensity of an earthquake from the information recorded by a seismometer. This record also provides information about the rocks the seismic waves traveled through.

Do Earthquakes Only Happen on Earth?
Earthquake is a name for seismic activity on Earth, but Earth isn’t the only place with seismic activity. Scientists have measured quakes on Earth's Moon, and see evidence for seismic activity on Mars, Venus and several moons of Jupiter, too!
NASA’s InSight mission took a seismometer to Mars to study seismic activity there, known as marsquakes. On Earth, we know that different materials vibrate in different ways. By studying the vibrations from marsquakes, scientists hope to figure out what materials are found on the inside of Mars.

InSight is collecting tons of information about what Mars is like under the surface. These new discoveries will help us understand more about how planets like Mars—and our home, Earth—came to be.
Wow what a lots of detailed information Bardsley! Its okay to write a shorter paragraph in your own words but thanks for copying so much for us to read.
