Therefore, all the energy of an earthquake is not always radiated from the focus, and for this reason the focus of an earthquake is not always the only source of seismic waves (Wampler, 2002). 5.

New evidence suggests current estimates about tsunami size and how quickly waves make it to shore may be too high and too ...

A phase change in post-perovskite materials at the so-called D” discontinuity is also evidence for long-predicted slow, convective flows in the mantle itself ...

Seismic Cloak Successfully Deflects Earthquake Waves Engineers are experimenting with a variety of ways to cloak vital infrastructure—even entire cities—from earthquakes. By Phil McKenna ...

Two Harvard seismologists, Miaki Ishii and Adam Dziewonski, first proposed the idea of the innermost inner core in 2002 based on peculiarities in the speed of seismic waves passing through the ...

How will three identically engineered buildings react to an earthquake on different types of substrate? The first set of waves to be detected by seismographs are P waves, or primary waves, as they’re ...

Seismologists study earthquakes by looking at the damage that was caused and by using seismometers. A seismometer is an instrument that records the shaking of the Earth's surface caused by seismic ...

A new kind of earthquake has been detected in western Canada, one that shakes the ground slower and longer than typical ...

A pioneering new approach to wave science could help improve early warnings for earthquakes, optimise renewable energies and advance medical diagnostics, researchers have said. A team of ...

Earthquakes may be triggered by sound waves that reduce the friction between rocks at a geological fault. That is the conclusion of an international team of researchers that has done laboratory-based ...

In a new study, Wu’s team developed and tested a way to use earthquake-generated sound waves traveling across the East Indian Ocean to estimate temperature changes in those waters from 2005 to 2016.
