Description
Summary:THE EXPLOSIONS WERE COLLOCATED WITH THE EARTHQUAKES IN EITHER THE Kuriles or Kamchatka regions and estimates of the mask time intervals are given for these cases. The results of the experiments are extended in order to estimate the total time, during the decade 1961-1972, that an explosion of a given magnitude in either central Asia, the Kuriles, or Kamchatka would have gone undetected at LASA due to the seismicity of the latter two regions. This total mask time, under various assumptions, is quantified into separate time intervals in the cases where the explosions and earthquakes are collocated. A result of this quantification is that, in the context of this experiment, there were a maximum of 300 two minute time intervals during the decade that a magnitude 5.0 explosion in the Kuriles might possibly have gone undetected at LASA, and 10 such intervals that the explosion most probably would have gone undetected, due to the seismicity of the Kurile Islands region.
