Abstract:

We have assembled data from a number of portable seismic experiments mounted in the last few years driven largely by an interest in the structure and dynamics of the India-Asia collision. We have used data collected in these experiments, as well as broadband data collected on a number of national and private networks, along with global seismic stations to produce a high quality regional catalogue with a detection threshold less than magnitude 3 for most of the middle east and central Asia. We developed a new grid-based implementation of the progress multiple event location. A second parallel effort is to apply waveform correlation methods to the entire dataset. Waveform correlation can dramatically improve measurement precision, but it can only be done successfully when waveforms are similar enough to allow correlation.
