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:

    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:

    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:

    How do earthquakes happen?

    A:

    Earthquakes happen when rock beneath the earth suddenly moves. Stresses in the earth make blocks of rock break and move along a fault line, which is a crack in the earth. The rocks may move, slip downward, upward or sideways. Many earthquakes take place on the edge of the seas. As of 2014, earthquakes can't be prevented but can be somewhat predicted.

  • Q:

    How do we measure earthquakes?

    A:

    The strength of an earthquake is measured by its Moment Magnitude Scale, or MMS. The MMS measures the total energy, or seismic moment, of an earthquake. The seismic moment of an earthquake is measured based on three factors: the distance rocks slide, the area of the fault slide and the rigidness of the rocks that are broken.
