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... |

A new study by researchers in the United States indicates that the sudden release of ozone in the atmosphere – detectable as spikes in the usual concentrations – could be used as an indicator that a large earthquake is imminent.
The group explains that rocks fracturing underground tend to release this t... |

A team of geologists and seismologists studying the April 4, 2010, El Mayor-Cucapah earthquake in Baja California, Mexico, discovered that the fault lines the event ruffled up were more crumpled underground than they were on the surface. A tremor usually causes the opposite effect. When an earthquake occurs, fault l... |

After more than a year after the April 4, 2010 Baja California earthquake, geologists are beginning to piece together what happened. They are very interested in why the shallow, magnitude-7.2 tremor occurred at depth of only 10 kilometers (6.2 miles),Seismologists identified the epicenter of the second-largest earthq... |

People usually find out very fast when two locked fault lines slip from each other's grip, as this is when earthquakes are produced. But new data analyzes how fault lines can slip against each other slowly, without triggering these powerful events. In order to arrive at this conclusion, experts investigated the ... |

Reports that appeared in the Russian over the past couple of days quote the opinion of seismologists saying that a new earthquake could hit Japan. A fault line relatively close to the one that spawned the March 11 tremor has great potential for producing a strong seismic event. The conclusion belongs to an analysis m... |

Experts say in a new scientific study that the January earthquake which struck the impoverished nation of Haiti did not release all of the tension accumulated in the tectonic plates surrounding the area. The main implication for this is that future quakes are still possible in the region. They could be of varied magn... |

In a groundbreaking new finding, a team of experts managed to establish that the devastating tsunami which struck the southwest Pacific islands of Samoa and Tonga last fall was not caused by one, but by two massive earthquakes. At this point, details are sketchy, in the sense that scientists don't really know wh... |

Scientists have for a long time wondered as to why certain mid-continental fault lines rupture even when they are not sited directly atop tectonic plate boundaries. Such is the case for example with the New Madrid fault line, which lies southwest from New Madrid, Missouri. Oftentimes, it produces what are known as in... |

In the aftermath of the January 12, magnitude-7 earthquake that struck the nation of Haiti last month, two deadly tsunamis formed in the waters off the island. These waves naturally traveled until they met land, and formed walls of water up to three meters in height. The announcement was made on February 24 in Portla... |

According to geologists at the US Geological Survey (USGS), the 7.0-magnitude earthquake that struck Haiti on January 12 will continue to generate aftershocks for many months to come, or maybe even years. Naturally, the strength of these tremors will decrease over time, as evidenced by the fact that the January 20 af... |

A large number of the earthquakes that take place on the San Andreas fault line – one of the most active on the globe – are caused by tidal forces, experts say. These forces are generated by motions in the planet's crust, they explain, which make the tectonic plates on top tremble. The extreme tensio... |

For a long time, geologists and seismologists have noticed that some fault lines, which are generally considered to be very stable and strong, tend to “slip up” at some points and become mobile. The scientific community has had no explanation for this phenomenon, so researchers have set out to discover wh... |

The massive, 8.0-scale tremor that struck the Sichuan province in China on May 12, 2008, claimed the lives of more than 85,000 people. It also caused massive damage to the country's infrastructure, and was felt in Beijing, some 1,500 kilometers away from its shallow epicenter, just 12 miles beneath the surface. ... |

The commonly accepted model of our planet states that the thick core is surrounded by a massive layer of magma known as the mantle, on which the tectonic plates that make up the crust float. When these plates meet, in areas known as fault lines, they collide against each other. When these collisions are delayed, tens... |
