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 ...

Seismic readings of the interior of Mars strongly suggest large quantities of water buried 6 to 12 miles underground.

Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.

Ground sensors like those used on the moon and Mars can measure seismic waves. Balloon-based pressure sensors can measure infrasound waves, a form of low-frequency waves in the atmosphere created ...

A seismometer is an instrument that records the shaking of the Earth's surface caused by seismic waves. The term seismograph usually refers to the combined seismometer and recording device. The first ...

The DAS sensors were sensitive enough to measure the small shaking caused ... which is typically buried just below ground level. Seismic waves moving through the ground cause the cable to wiggle ...

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 ...

Seismic waves passing through these soft sediments ... next to investigate shallow subsurface structures in Singapore and "measure small changes of seismic velocity to track changes in water ...
