Strike, Dip, and Rake. (adapted from page 106 of Aki & Richards (1980), Quantitative Seismology - Vol 1) Strike - the fault-trace direction in decimal degrees (0 to 360, relative to North), defined so that the fault dips to the right side of the trace. That is, the fault always dips to the right when moving along the trace in the strike ...

But their geographic locations aren't fixed: As the Earth's axis moves, so do the poles. A study published in March 2021 found that Earth's axis started shifting drastically in 1995, speeding the ...The Modified Mercalli intensity scale ( MM, MMI, or MCS) measures the effects of an earthquake at a given location. This is in contrast with the seismic magnitude usually reported for an earthquake. Magnitude scales measure the inherent force or strength of an earthquake – an event occurring at greater or lesser depth. The largest azimuthal gap between azimuthally adjacent stations (in degrees). In general, the smaller this number, the more reliable is the calculated horizontal position of the earthquake. Earthquake locations in which the azimuthal gap exceeds 180 degrees typically have large location and depth uncertainties.A measure of the strain energy released by an earthquake within 100 kilometers of its epicenter.
