    In the (low seismicity) United Kingdom, for example, it has been calculated that the average recurrences are: an earthquake of 3.7–4.6 every year, an earthquake of 4.7–5.5 every 10 years, and an earthquake of 5.6 or larger every 100 years. [42] This is an example of the Gutenberg–Richter law.

    en.wikipedia.org/wiki/Earthquake_Cycle

    The earthquake cycle refers to the phenomenon that earthquakes repeatedly occur on the same fault as the result of continual stress accumulation and periodic stress release. [ 1 ] [ 2 ] Earthquake cycles can occur on a variety of faults including subduction zones and continental faults.

    This subduction zone is one of the most active plate boundaries globally, moving at a rate of approximately 170 mm (7 in) per year. [5] While much of the island arc experiences intermediate-depth earthquakes along a Wadati–Benioff zone that dips steeply at 70°, the area adjacent to the D'entrecasteaux Ridge does not. There is a corresponding ...

    en.wikipedia.org/wiki/Seismogram

    Seismograms typically record motions in three cartesian axes (x, y, and z), with the z axis perpendicular to the Earth's surface and the x- and y- axes parallel to the surface. The energy measured in a seismogram may result from an earthquake or from some other source, such as an explosion.
