Seismology¶

7 domain-specific abstractions whose origin domain is Seismology.

Deep-Focus Earthquake — An earthquake whose hypocenter lies deeper than 300 kilometres, overwhelmingly within cold subducted lithosphere, where earthquake-like shear rupture persists despite pressure and temperature conditions hostile to ordinary shallow brittle failure.
Earthquake forecasting — Estimate the probability or expected rate of earthquakes within declared future time, location, and magnitude windows rather than naming one exact impending event.
Forensic seismology — Use recorded seismic signals, propagation models, provenance, and uncertainty-aware comparison to detect, locate, characterize, and evidentially attribute remote events for treaty, legal, historical, or incident investigation.
Gutenberg–Richter law — An empirical log-linear relation in which the number of earthquakes at or above magnitude M decreases approximately as ten to the power a minus bM.
Harmonic tremor — A sustained seismic or infrasonic signal with narrow spectral bands or overtone-like peaks, often associated with volcanic fluid motion but also generated by nonvolcanic repetitive sources.
Love wave — A horizontally polarized shear surface wave guided by an elastic layer over a half-space.
Teleseism — Seismic motion from an earthquake recorded at a great epicentral distance, commonly beyond regional distances where waves traverse deep Earth paths.
