Evolving Uses for Dense Geophone Arrays in Solid Earth and Environmental Seismology
Dr. Brandon Schmandt, University of New Mexico

ABSTRACT

Among the portable instruments used by seismologists, cable-free seismographs containing geophones have seen expanded use in recent years for collecting continuous seismic data. Such rapidly deployable autonomous recording units are often referred to as ‘nodes.’ The webinar will serve to introduce some of the strengths and limitations of nodal arrays through examples from ongoing collaborative research. The primary examples used will be from nodal arrays used to study the Mount St. Helens magmatic system in Washington and management of coarse sediment transport for salmon fishery restoration at the Trinity river in northern California.
