Our Team

50+ years of combined experience in developing & implementing seismic monitoring solutions

Peter E. Malin – Director of Development

Peter brings more than 40 years of experience in borehole seismology and geophysical research to ASIR. Peter is known for his work in borehole seismology, instrument design and installation, seismic monitoring, and fracture research. Peter has been responsible for the design, installation and monitoring in sites around the globe, including USA, New Zealand, Iceland, Kenya, Taiwan, Turkey, Switzerland, Caribbean, Israel, Japan, Central America, Saudi Arabia and China. He was instrumental in the seismic monitoring network at the San Andreas Fault Observatory at Depth (SAFOD), resulting in the discovery of a new type of seismic wave in fault.

Peter’s endeavors into seismic instrumentation and exploration include as founder of Sondi in California and more recently as Director of IESE – the Institute of Earth Science and Engineering -­ a research and development institute in Auckland, New Zealand. Peter led the institute in the study of the crust’s active tectonic and hydrothermal systems and developed new modes of data gathering, modeling and instrumentation. The resulting knowledge and technology innovations have afforded practical application in the fields of geological hazards, energy exploration, resource evaluation and subsurface monitoring.

Focal interests of Peter’s work have included fault zone guided waves and the interaction of faults and fractures with subsurface fluids, along with the study of “joint geophysical imaging” of fracture zones using seismic, electromagnetic, and potential field methods. More recent work has also centered on fracture permeability enhancement.

Kevin Passmore – Director of Services

Kevin Passmore - 675

Kevin joins ASIR from a background in engineering and manufacturing. He is instrumental in the design, manufacturing, and quality assurance for ASIR’s posthole and borehole seismometers.

Throughout the past 10 years, Kevin’s work has included field installations for seismic monitoring within the US and abroad.

Peter Leary – Chief Scientist

Peter Leary

Peter spent 20 years in academic research in the US earthquake hazards reductions program as staff member of Princeton University and University of Southern California. He then joined the University of Edinburgh to apply borehole seismic technology to improve oil production by time-­lapse borehole seismic imaging of fracture-­heterogeneous hydrocarbon reservoirs. Peter also consulted for Geospace Engineering Resources International (GERI) in developing crosswell seismic applications to time-­lapse monitoring of tight-­gas formations.

In 2008 Peter joined IESE, the Institute of Earth Science and Engineering, in Auckland, New Zealand, where he applied theoretical and field development practices to dynamic reservoir studies in active geothermal fields with the goal of achieving EGS power-­generation capability through better understanding of fluid flow in fractured rock and the stimulation of in situ fractures.

Focal points of Peter’s work include fluid flow modelling, permeability enhancement and EGS in the USA, China, Europe, New Zealand and Australia. Peter has authored or co­-authored 50 journal papers and 50 conference abstracts in crustal deformation, seismic observation and instrumentation, and simulation of percolation flow in critical state fractured media for application to geothermal reservoirs.

In memory of Dr. Eylon Shalev

Agronome, Meteorologist, Seismologist


On November 14, 2015 Eylon Shalev passed away without notice, sitting in his easy chair. He leaves us with the example of a life richly lived and generously shared.

While in the Research Triangle Eylon found an academic home at Duke University as a research scientist. He contributed important insights to SAFOD site velocity structure, built instruments for PBO, and located geothermal resources in the four corners of the world with new methods in shear-wave splitting tomography. In 2008 he became Associate Director of the Institute of Earth Science and Engineering in Auckland, New Zealand, returning to Raleigh in 2014.

We will miss his sweeping, unique council and his support of family, friends, and colleagues.
