A Regional Crustal Phase Observatory.

Abstract

A ten-element array of short period seismometers and a broadband instrument will be installed in early 1995 at Blue Mountains Observatory (BMO) in northeastern Oregon. BMO operated as a VELA array from 1962 to 1975. It is being reactivated to provide a high-quality data base on regional crustal phase propagation through varying geologic provinces. In particular, BMO data will be used to identify crustal phases useful in determination of event focal depth. Numerous crustal events occur annually at regional distances around BMO, and the depths of many of these events are well-constrained by virtue of occurring within regional telemetered networks. We will use BNO data in assessing how well a small-aperture array performs in discriminating blasts from earthquakes on the basis of focal depth determined from regional phases. This document provides an overview of ENO and its instrumentation, including means of access of the digital data by interested users.
