  2. Earthquake rupture - Wikipedia

    en.wikipedia.org/wiki/Earthquake_Rupture

    A tectonic earthquake begins by an initial rupture at a point on the fault surface, a process known as nucleation. The scale of the nucleation zone is uncertain, with some evidence, such as the rupture dimensions of the smallest earthquakes, suggesting that it is smaller than 100 m while other evidence, such as a slow component revealed by low-frequency spectra of some earthquakes, suggest ...

  3. Earthquake early warning system - Wikipedia

    en.wikipedia.org/wiki/Earthquake_early_warning...

    Japan's Earthquake Early Warning system was put to practical use in 2006. The system that warns the general public was installed on October 1, 2007. [25] [26] It was modeled partly on the Urgent Earthquake Detection and Alarm System (UrEDAS ) of Japan Railways, which was designed to enable automatic braking of bullet trains. [27]

    en.wikipedia.org/wiki/Seismology

    Seismology (/ s aɪ z ˈ m ɒ l ə dʒ i, s aɪ s-/; from Ancient Greek σεισμός (seismós) meaning "earthquake" and -λογία (-logía) meaning "study of") is the scientific study of earthquakes (or generally, quakes) and the generation and propagation of elastic waves through planetary bodies.

  6. Earthquake prediction - Wikipedia

    en.wikipedia.org/wiki/Earthquake_prediction

    In southern California about 6% of M≥3.0 earthquakes are "followed by an earthquake of larger magnitude within 5 days and 10 km." [12] In central Italy 9.5% of M≥3.0 earthquakes are followed by a larger event within 48 hours and 30 km. [13] While such statistics are not satisfactory for purposes of prediction (giving ten to twenty false ...

  7. Earthquake engineering - Wikipedia

    en.wikipedia.org/wiki/Earthquake_engineering

    Earthquake or seismic performance defines a structure's ability to sustain its main functions, such as its safety and serviceability, at and after a particular earthquake exposure. A structure is normally considered safe if it does not endanger the lives and well-being of those in or around it by partially or completely collapsing.

  8. Earthquake preparedness - Wikipedia

    en.wikipedia.org/wiki/Earthquake_preparedness

    Earthquake modification techniques and modern building codes are designed to prevent total destruction of buildings for earthquakes of no greater than 8.5 on the Richter Scale. [4] Although the Richter Scale is referenced, the localized shaking intensity is one of the largest factors to be considered in building resiliency.

  9. Volcano tectonic earthquake - Wikipedia

    en.wikipedia.org/wiki/Volcano_tectonic_earthquake

    A volcano tectonic earthquake or volcano earthquake is caused by the movement of magma beneath the surface of the Earth. [1] The movement results in pressure changes where the rock around the magma has a change in stress. At some point, this stress can cause the rock to break or move. This seismic activity is used by scientists to monitor ...
