Earthquake Hypocenter data base available
A magnetic tape containing hypocenter data for 40,000 earthquakes from January 1961 through August 1970 is now available from NOAA's National Geophysical Data Center. These data were used by the National Ocean Survey (formerly Coast and Geodetic Survey) to produce World and Regional Seismicity Maps.

The authors have retracted this article [1] because after its publication, they noticed that the source inversion was not done with the intended setting. Although it was mentioned in this article [1] that the rupture starting point of the fault model was

Volcanic earthquake swarms at Izu-Oshima in 2023
Earthquake swarms are known to reflect underground fluid movement and stress changes. However, their occurrence patterns and the mechanisms underlying hypocenter migration remain poorly understood.

INTERPRETING FAULT DYNAMICS IN TERMS OF HYPOCENTER RELOCATION AND FAULT CHARACTERIZATION
Southeast and Central Sulawesi are the areas characterized by high tectonic activity due to the presence of the active Matano fault. The seismicity along this fault is high. However, the initial hypocenter often deviates from the fault’s trend line, thus

Numerical investigation of dilatancy biasing of hypocenter locations
We assume that a dilatant zone which develops as a precursor to an earthquake may be modeled by a zone of low‐velocity rock having the shape of a triaxial ellipsoid. For varying ellipsoid dimensions, velocity contrasts, and hypocenter distributions, we generate a synthetic data set of arrival times at surface stations.

An approach for teleseismic location by automatically matching depth phase
To deal with the low efficiency problem of accurate teleseismic hypocenter location, this paper proposes a fully automatic approach by integrating the advantages of Seismic-Scanning based on Navigated Automatic Phase-picking, which can automatically ...
