[10DotMatrix] has a budding interest in seismology, so she decided to make her own seismometer out of some easy-to-find materials. Seismometers are prohibitively expensive for hobbyists ...

Thus, the cables act as arrays of hundreds of seismometers. Now ... waves of seismic energy radiate outward from its hypocenter, an earthquake's point of origin underground.

There are a number of ways to measure the magnitude of an earthquake. Most scales are based on the amplitude of seismic waves recorded on seismometers. These scales account for the distance between ...

When comparing the original laser signal with the light that exits the fiber optic cable, researchers can determine the strength of the seismic wave by checking how much the beam was distorted. Data ...
