Regional Location and Identification Using Sparse Stations
نویسندگان
چکیده
Locating events in Southern California is quite simple since we have about 500 stations, with a large fraction broadband (TriNet). We locate and identify within minutes. Thus, we have an opportunity to test hybrid methods against the full array estimate. Here we report on three projects addressing these issues; (1) locating events using one calibrated station with waveform data plus a few other stations with travel-time and polarity information, (2) particularly complex sub-regions where the depth phases such as pPn and sPn prove ineffective, and (3) calibrating paths using a combination of sparse regional waveforms and radar.

Lg-Wave Cross Correlation and Double-Difference Location: Application to the 1999 Xiuyan, China, Sequence
A surprising discovery has been made that in some cases the complex, highly scattered Lg wave is found to be similar for clusters of events. We analyze in detail a subset of 28 out of 90 events from the 1999 Xiuyan sequence. Cross correlations provide highly accurate differential travel-time measurements. Their error estimated from the internal consistency is about 7 msec. These travel-time dif...

Increasing the use of fossil fuels is with severe environmental and economic problems, bringing more attention to alternative fuels. The compressed natural gas (CNG), as an alternative fuel, offers many more benefits than gasoline or diesel fuel such as cost-effectiveness, lower pollution, better performance, and lower maintenance costs. Gas stations location and the number of gas stations are ...
متن کاملDevelopment and Testing of a 3D Velocity Model for Improved Event Location: A Case Study for the India–Pakistan Region
3D velocity models will play an important role in improving location accuracies of small events within the context of a comprehensive nuclear-test-monitoring treaty. Commonly, such models are developed using tomographic methods that require the initial velocity model to be a reasonable approximation of the true Earth structure. In this article, we present a method for the development of an a pr...
