  2. Epicenter - Wikipedia

    en.wikipedia.org/wiki/Epicenter

    By measuring the time difference on any seismograph and the distance on a travel-time graph on which the P wave and S wave have the same separation, geologists can calculate the distance to the quake's epicenter. This distance is called the epicentral distance, commonly measured in ° (degrees) and denoted as Δ (delta) in seismology.

  3. Hypocenter - Wikipedia

    en.wikipedia.org/wiki/Hypocenter

    Hypocenter (Focus) and epicenter of an earthquake. An earthquake's hypocenter or focus is the position where the strain energy stored in the rock is first released, marking the point where the fault begins to rupture. [3] This occurs directly beneath the epicenter, at a distance known as the hypocentral depth or focal depth. [3]

  4. Epicentral distance - Wikipedia

    en.wikipedia.org/wiki/Epicentral_distance

    Even if the depth of focus of an earthquake is very deep, it can still have a very short epicentral distance. [3] When measuring the epicentral distance of an earthquake with a small epicentral distance, first measure the reading of the initial motion of P wave, and then confirm the arrival of S wave.

  5. Travel-time curve - Wikipedia

    en.wikipedia.org/wiki/Travel-time_curve

    Travel time in seismology means time for the seismic waves to travel from the focus of an earthquake through the crust to a certain seismograph station. [1] Travel-time curve is a graph showing the relationship between the distance from the epicenter to the observation point and the travel time.

  6. Earthquake - Wikipedia

    en.wikipedia.org/wiki/Earthquake

    The initial point of rupture is called the hypocenter or focus, while the ground level directly above it is the epicenter. Earthquakes are primarily caused by geological faults, but also by volcanic activity, landslides, and other seismic events. The frequency, type, and size of earthquakes in an area define its seismic activity, reflecting the ...
