On the possibility of the seismic detection of explosions from the signs of first onsets
A. E. SCHEIDEGGER

Abstract
It is shown that, for an earthquake region, critical areas can be derived inside which one would expect seismic stations to observe a dilatation in the first onsets. Thus, if compressions are observed inside the critical area, one has grounds for the assumption that the "earthquake" was an explosion. As an example, critical areas are calculated for Turkmenia and the Tien Shan region.
