About PASSCAL

PASSCAL Facility

The Incorporated Research Institutions for Seismology (IRIS) Portable Array Seismic Studies of the Continental Lithosphere (PASSCAL) Instrument Center and EarthScope USArray Array Operations Facility (AOF) at New Mexico Tech support cutting-edge seismological research into Earth’s fundamental geological structure and processes. The facility provides instrumentation for National Science Foundation, Department of Energy, and otherwise funded seismological experiments around the world. PASSCAL experiment support includes seismic instrumentation, equipment maintenance, software, data archiving, training, logistics, and field installation.

Continued expansion of IRIS activities at New Mexico Tech via the EarthScope and other initiatives has spurred a major facility expansion, the EarthScope USArray Array Operations Facility. The AOF was officially dedicated on April 6, 2005 by the New Mexico Tech administration and the IRIS Board of Directors. The combined PASSCAL Instrument Center and AOF currently support a total of 33 professional New Mexico Tech staff, as well as a contingent of student workers.

PASSCAL and USArray Flexible Array equipment is available to any research or educational institution to use for research purposes within the guidelines of established policies. These policies provide that data collected with PASSCAL and/or USArray equipment be archived at the IRIS Data Management Center and that the data are openly available to the community. Instruments can be requested online using the PASSCAL Instrument Request Forms.

RT130 ALERT - Issue when using two 4GB CF cards

Jan. 5, 2015

PASSCAL recently received reports of RT130’s failing when using two RefTek 4G CF cards at moderately low temperatures during an Antarctic experiment. We have duplicated the failure in our lab and in our testing the failure was associated with a specific version of RefTek well board (RT526D). Although we have not had failures in our testing with earlier or later versions of the board, our sample set is small and we cannot rule out problems with these boards when using two 4G CF cards. We have communicated with RefTek about the issue and at this time they are in agreement with these findings.

Conviction of Italian Seismologists Overturned in Appeal

Angus Mackinnon of phys.org reported on November 10th, 2014 that

"Seven Italian scientists who faced jail for failing to predict a deadly 2009 earthquake were cleared Monday of manslaughter convictions that had sparked international outrage.

The seven men were sentenced to six years in jail in October 2012 after a court in the medieval town of L'Aquila found them guilty of causing multiple deaths by having negligently downplayed the risk of the town being hit by a major earthquake just days before the killer tremor struck in April 2009."

Aftershock Deployment in Wine Country

 

 On August 27, 3:22 am Napa, California experienced a M=6.0 earthquake,   causing significant damage to buildings in downtown and in the world-renowned vineyards of central Californa.  Dr. Rufus Catchings of the USGS' Menlo Park office led a deployment team consisting of USGS staff and volunteers, supported by George Slad of PASSCAL.

 

Pre-AGU PASSCAL Users Workshop 2014

Late-stage graduate students! Postdocs! Researchers and faculty!

IRIS/PASSCAL Instrument Center would like to invite you to register for our PASSCAL Users Workshop to be held on Sunday December 14th, 2014 (the day before the beginning of the AGU Fall meeting). 

This year’s workshop will give an overview of the PASSCAL facility, the services we provide and how to access them.  We will have two special guest speakers, PIs who have successfully planned for an run international and large-scale PASSCAL projects.  This year's speakers are Anne Meltzer of Lehigh University (large-scale broadband deployments in Pakistan, Tibet, and Mongolia) and David Okaya of the University of Southern California (large active source projects in Taiwan, New Zealand and Japan).

But wait, there is more! The PASSCAL Program Manager, Kent Anderson, as well as the PASSCAL Director, Bruce Beaudoin, will be on hand for questions and discussion as well.  Ask questions and discuss ideas about current/future projects before AGU really starts and the talks, posters, dinners, and other meetings start clamoring for everybody's attention and time!

This workshop will be useful to anyone who has an upcoming PASSCAL supported experiment, or is planning to propose an experiment, and will be particularly useful to current graduate students and new investigators.

PASSCAL Intern Winds Up Summer With "Ultrasound" of Mt. St. Helens

Federica Lanza, a Ph.D. student at Michigan Technological University under Gregory P. Waite, spent the summer as the IRIS/PASSCAL intern. During that time, "Fede" deployed instruments with IRIS interns, presented her work at the 2014 IRIS workshop, and completed two research projects related to short period sensor responses and long period noise analysis using PSD PDFs. Fede wrapped up her summer with a couple of weeks in the field at Mt. St. Helens, supporting the iMUSH project, along with several other IRIS/PASSCAL scientists and staff. Some highlights of our intern's busy summer follow.
