Q:

What state has the most earthquakes?

A:

Quick Answer

The U.S. Geological Survey reports that, as of 2014, Alaska accounts for about half of all earthquakes registered in the United States. The USGS also indicates that many smaller magnitude earthquakes go unreported in the state. California has the second-most reported earthquakes among U.S. states.

Full Answer

Hawaii is the third-most prominent earthquake state and Nevada is fourth. However, the USGS site reports that these states are in a virtual dead heat on the number of quakes with a 5.0 or greater magnitude. Other states listed in the top 10 include Washington, Idaho, Wyoming, Montana, Utah and Oregon. The rankings include any quakes reported in any region within a state.

  • Q:

    What causes earthquakes?

    A:

    The surface of the earth is called the crust, and it is made up of plates, called tectonic plates, that move. Earthquakes happen when these plates bump, scrape or drag against each other.

  • Q:

    Why do earthquakes happen?

    A:

    Earthquakes are the result of two of the Earth's crustal plates slipping past each other, otherwise known as plate tectonics. The vibrations caused by this sudden movement reverberate through the surrounding rock structures, and they are felt as tremors. Earthquakes are most common among the geologically active regions at the borders between plates of the Earth's crust, also known as fault zones.

  • Q:

    Where do earthquakes form?

    A:

    According to the U.S. Geological Society, the area in the Earth's crust where an earthquake forms is called the hypocenter. Unpredictable in nature, earthquakes form when energy from the crust is released, causing vibrations on the surface of the earth. The magnitude of earthquakes can vary exponentially, and the stronger the magnitude, the more devastating the effects, especially on areas that are near the epicenter.

  • Q:

    How do earthquakes occur?

    A:

    Earthquakes occur when two blocks of earth suddenly slip past each other. This sudden release of energy causes the seismic waves that make the ground shake. The surface where they slip is known as the fault or fault plane.
