Earthquakes, volcanic eruptions, shifting tectonic plates—these are all signs that our planet is alive. But what is revealed ...

Seismological research is directly related to the incubation, occurrence, and evolution of earthquakes. Scientists seek to ...

A little over 20 years later, in September 2018, a second big earthquake hit the same location, its waves of seismic energy emanating from the same region. Though the earthquakes occurred two ...

Seismic waves, however, are not all the same. During an earthquake (or marsquake), four main types of waves are generated: p-waves, s-waves, Love waves, and Rayleigh waves. P-waves and s-waves ...

When the Earth’s crust shifts abruptly, an earthquake occurs, with energy radiated out as seismic waves and shaking that’s sometimes experienced by people, buildings and infrastructure.

Earthquakes occur when two plates suddenly slip past each other, setting off seismic waves that cause the planet's surface to shake, according to the USGS. An earthquake is what happens when the ...

The seismic waves ... specializes in unusual earthquakes. “It doesn't mean that, in the end, the cause of them is that exotic,” he notes. Yet many features of the waves are remarkably weird ...

When there is too much friction between the fault lines, energy is released suddenly, triggering seismic waves which lead to an earthquake.

Analyzing the crisscrossing of seismic waves from large earthquakes, two Australian scientists say there is a distinctly different layer at the very center of the Earth. “We have now confirmed ...

Ryan Sun / AP When the 4.4-magnitude earthquake struck the Los Angeles ... because the soil effectively amplifies the seismic waves, while those located on harder rocky surfaces may feel a weaker ...
