High Precision Continuous Monitoring and Analysis of Active Faults and Volcanoes

The overall focus of my work has been to (1) understand the mechanics of failure of active faults and volcanoes using a variety of instruments that have included magnetometers, tiltmeters, linear and tensor strainmeters, telluric current monitors, differential lake level, borehole tensor and dilational strain, volcano displacement monitors, etc., (2) develop physical models describing crustal failure from the analysis of data from these instruments and (3) determine implications for the physics of the earthquake source from these data. This requires conceiving the research, designing instruments and data collections systems, organizing construction and installation, analyzing data and writing papers. This has required supervision of from 2 to 12 people at various times. The various instruments, in most cases, are not available commercially and must be designed and constructed within the USGS. Systems  that include digital telemetry for monitoring these data from remote sites, computer systems for retrieval and display of these data, analysis techniques and programs for interpretation of the observations obtained were set up in order to obtain, analyze and interpret these data in real time. Recent impacts of this work have been from:

[1] Design and installation techniques for borehole strain, tilt, pore pressure and seismic monitoring systems that was used exclusively by the National Science Foundation for installation of 68 new borehole sites in western US as part of the new national Earthscope program.

[2] Design, installation of instruments including data collection system for deep mine monitoring of high frequency (12 KHz) seismic velocity/acceleration, strain, fault creep, fault zone temperature, and electromagnetic signals. This is now the state-of-the- art for these measurements. There is no other system operating anywhere else in the world other than ours at 3.6 km depth in Tau Tona mine in South Africa.

[3] Detection of  “slow earthquakes” and slow slip events and their relation to tremor and the occurrence of large plate-boundary earthquakes is now a major focus area in seismology and geodesy, particularly in the USA, Japan, Mexico, Chile, Greece and Turkey.

[4] Identification of electromagnetic effects associated with the earthquake failure process currently defines the current state of this field of geophysics.

[5] Design of volcano monitoring systems using borehole tiltmeters and strainmeters, pore pressure and electromagnetic systems has been implemented in Hawaii, Japan, Italy and on many other volcanoes throughout the world. The most recent was Taal volcano in the Phillipines, installed in January 2010, just in time to catch the volcanic crisis in May-June, 2010.
