National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Phenomenology Research Using Past Nevada Test Site Explosion and Earthquake Data.

DE200515013168

Publication Date	2000
Personal Author	Mayeda, K. M.; Pasyanos, M. E.; O'Boyle, J.; Myers, S. C.; Walter, W. R.
Page Count	10
Abstract	We use regional waveform data from the Nevada Test Site (NTS)to investigate phenomenological relationships between recorded amplitude and explosion yield as well as test regional depth estimation procedures. Our goal is to better understand the performance of seismic observables in other regions of monitoring interest, especially at small magnitudes (mb<<4.5). Some of the topics we are studying include: stable yield estimation, depth estimation, and M(sub s):m(sub b) performance. We use Lawrence Livermore National Laboratory's NTS explosion database, which consists of several hundred events ranging from -200- to -1500-m depth and yields ranging from a few tenths of a kiloton to the megaton range. In addition to the broadband explosion data, we have a large dataset of well-located earthquakes on the test site with depths ranging from 2 to 17 km and magnitudes ranging between Mwl.5 and 5.7.
