The Difference between Foreshocks and Earthquake Swarms, as Inferred from the Similarity of Seismic Waveform (Preliminary Report)

, 1979
The earthquake swarms occurred at seven areas distributed in the Kanto district and foreshocks preceding the Izu-Oshima-kinkai earthquake (M=7.0) of 1978 are studied through the analysis of waveform.

Central California foreshocks of the great 1857 earthquake [PDF]

, 1978
Analysis of contemporary accounts indicates that several small to moderate central California earthquakes preceded the great 1857 earthquake by 1 to 9 hr.

The Mw 8.1 2014 Iquique, Chile, seismic sequence: A tale of foreshocks and aftershocks

, 2016
The 2014 April 1, Mw 8.1 Iquique (Chile) earthquake struck in the Northern Chile seismic gap. With a rupture length of less than 200 km, it left unbroken large segments of the former gap.

High frequency radiation and foreshocks during laboratory earthquakes

, 2020
Au cours de cette thèse, nous avons reproduit expérimentalement des séismes à l’échelle centimétrique dans des conditions de pression proches de la réalité.

A change in fault-plane orientation between foreshocks and aftershocks of the Galway Lake earthquake, M_L = 5.2, 1975, Mojave desert, California

, 1979
A marked change is observed in P/SV amplitude ratios, measured at station TPC, from foreshocks to aftershocks of the Galway Lake earthquake. This change is interpreted to be the result of a change in fault-plane orientation occurring between foreshocks ...

Foreshocks or swarms? Insights from theory and statistical analysis

Are foreshocks “fore-shocks” or simply markers of local instability without any prognostic value about future large-scale mainshocks? We try to answer this question using both theoretical modelling and statistical analysis of clusters listed in relocated
