Huddle testing feedback-sensors and dataloggers

Introduction

“Huddle”-testing sensors before field deployment is a key part of any seismic experiment.  Huddle-testing involves testing almost all components of the field station, for many stations, in parallel.  The number of stations that can be tested at one time is limited only by availability of personnel and lab space.

Huddle-testing potentially reduces crew time spent in the field, cost of the experiment, and the need to revisit sites.  Huddle-testing improves crew consistency and most importantly, the likelihood of successful station deployments and survival.

Western Idaho Shear Zone: is snow in the forecast?

FlexArray Experiment: Western Idaho Shear Zone

If this photo (below) of a 6' 1" tall individual looking up at the top of the solar panel mast doesn't cause one to wonder how much snow the mountains near Cornucopia, Oregon receive, a Snow Cat (below left) at a nearby lodge certain makes it's clear - lots of it. This temporary seismic station installed in the mountains of eastern Oregon is part of Dr. Ray Russo's Western Idaho Shear Zone Earthscope Flexible Array experiment. Spanning eastern Oregon to eastern Idaho, the seismic network covers arguably some of the most remote and rugged mountains of the contiguous United States.

PICASSO -SPAIN COMPONENT - Field work

PICASSO - Program to Investigate Convective Alboran Sea System Overturn

"PICASSO  consists of a multidisciplinary international investigation of the Alboran Sea, Gibraltar arc, Atlas Mountains and surrounding areas in the western Mediterranean using passive and active seismology, magnetotellurics, geochemistry/petrology/structural geology, and geodynamic modeling. The project was selected as the pilot experiment for TopoEurope, an EarthScope-like initiative recently approved by the European Science Foundation. The U.S. PICASSO investigators are from Rice (Lee, Levander), the University of Oregon (Humphreys), U.C. San Diego (Seber), WHOI (Chave, Evans), and the University of Southern California (Becker, Platt)". (From Original Proposal)

Array of Arrays: Elusive ETS in the Cascadia Subduction Zone

ETS, or 'episodic tremor and slip', is a recently discovered phenomenon in seismic research. Similar to earthquakes but much smaller in magnitude, ETS events are associated with the subduction zone of some convergent plate boundaries. One such region, the Cascadia subduction zone under the Puget Sound, is the focus of an experiment by Ken Creager's group at the University of Washington (UW), called Array of Arrays.

Sierra Negra Volcano, Galápagos Islands Deployment

In July and August of 2009, seven scientists deployed several seismic sensors for a two-year multidisciplinary study of one of the world's most active volcanoes, the Sierra Negra Volcano of the Galápagos Islands. The project's official name is “Collaborative Research: An integrated seismic-geodetic study of active magmatic processes at Sierra Negra volcano, Galápagos Islands.”
