Bridges, nuclear power plants, dams and other strategically-important buildings could be “cloaked” against the seismic waves earthquakes produce. This could be achieved by using innovative metamaterials, constructs that do not exist in nature, and which can easily steer seismic waves.
In other words, the... |

By comparing pictures and computer models of areas neighboring fault lines – taken both before and after a major earthquake occurs – scientists can now gain a deeper understanding of how these sectors of Earth's crust move and interact during seismic events.
Such investigations could come in very h... |

The results of a new geological analysis indicate that a rift in the US southwest is currently stretching and expanding, therefore increasing the risk of a major earthquake occurring in the region. The interesting thing about this is that the area is not exactly known for being too geologically-active.
The structur... |

Fin whales are magnificent, but poorly-understood, endangered creatures. Understanding their songs would be one of the keys to making sense of why they act the way they do, and now a group of seismologists has just found a way to do that.
The team said last week at the annual meeting of the American Geophysical Uni... |

As a magnitude 9.0 earthquake struck Japan on March 11, American and European satellites were monitoring the Pacific Ocean, looking for signs of tsunamis. In addition to seeing the waves develop and wipe out the country's coastlines, they also saw the first-ever hints of a merging tsunami.
Such a natural event... |
