Frequency-magnitude relationships are determined for a source region defined by a circular
epicentral area of 50 km radius centered on the Carnegie broadband seismograph at KMU …

Based on the dynamical mass-spring model proposed by Burridge & Knopoff (1967), the
effects on seismicity and the scaling exponent (ie the b value) of the frequency-magnitude …

Seismic anisotropy of the upper mantle beneath the central part of Peru is examined by
analyzing shear waves observed at broad-band stations and a temporary array of short …

The lack of a sharp boundary between North and South Atlantic stress fields recorded in the
arcs of transform faults and ridge segments suggests a gradual merging of mantle stresses …

Abstract The Loreto earthquake of 26 May 2019 occurred below the extreme northeast part
of Peru at a depth of 140 km within the subducting Nazca plate at a distance of 700 km from …

Abstract On May 26, 2019, an unusual depth-intermediate focus earthquake, in the interior of
the Nazca plate, shook the northern Peruvian jungle and caused the death of two victims …

Magnitude-frequency relations are investigated for the on-land area, covered by the Tohoku
University seismic network, northeastern Japan. We combine the Japan Meteorological …

The seismic activity in Peru has its origin in the convergence process between the Nazca
and the South American plates. Such convergence takes place at an average velocity on the …

A recent statistical analysis of the relationship between tides and seismic activity in
Colombia has suggested the existence of correlation anomalies for the case of intermediate …

Recent advances in the study of deep earth morphology are discussed in a critical review of
US research from the period 1987-1990. Sections are devoted to global-scale models of the …
