BMKG, the official institution responsible for producing of earthquake information

Azimuth gap

Azimuthal gap is the maximum angle separating two adjacent seismic stations, both measured from the epicenter of an earthquake. If azimuthal gap is more than 180°, the location accuracy degrades significantly. The detection capability of a network can be evaluated based on the relationship between magnitude and observation distance.
