Advanced Regional Array Studies
We have addressed the problem of optimizing the site-specific seismic threshold monitoring method in order to achieve the highest possible automatic monitoring capability of particularly interesting areas, such as the Novaya Zemlya testing area, and the Indian and Pakistani test sites. For the Novay...

We have addressed the problem of optimizing the site-specific seismic threshold monitoring method in order to achieve the highest possible automatic monitoring capability of particularly interesting areas, such as the Novaya Zemlya testing area, and the Indian and Pakistani test sites.

Based on data from the teleseismic network observing the Indian and Pakistani tests of 1998, we obtain a monitoring capability in the range m(sub b) 2.8-3.0 for these test sites.
