Summary Observations have been made of the local atmospheric pressure field and the long-period seismic noise fields both on the surface of the Earth and in a mine at a depth of 183 metres. The observations show that during windy intervals and in the

INTRODUCTION The Comprehensive Test Ban Treaty (CTBT) verification community is concerned with estimating capabilities to correctly identify the sources of regional seismic events whose magnitudes are in the range 2.5 < mb < 4.0. This interest has de

Hydraulic fracturing is a method commonly used to stimulate production in low‐permeability reservoirs. With this method, a viscous polymer‐based fluid is injected into the formation, opening a fracture perpendicular to the direction of least prin

Summary A comprehensive set of experiments including remote- and treatment-well microseismic monitoring, interwell shear-wave shadowing, and surface tiltmeter arrays, was used to monitor the growth of a hydraulic fracture in the Belridge diatomite. T

Earth motion in response to atmospheric pressure changes is a major contributor to the ambient seismic background in the 20- to 100-s period range. During windy intervals at the surface the quasi-static deformations caused by wind-generated pressure

The performance of long-period seismographs is often seriously degraded by atmospheric pressure variation; the problem is particularly severe at periods greater than 20 sec. The pressure variations associated with wind-generated turbulence and acoust

General expressions for the transfer function and the coherence, relating earth motion and atmospheric pressure variations observed at the surface, are derived for the case where the pressure field is a random process which is stationary in both time

In recent years there has been increasing interest in the role of geothermal steam as a source of energy. Only recently has geophysical exploration begun to play a major role in the exploration for geothermal resources; heat flow, gravity, and resist
