ARRAYS in Global Seismology Workshop
Raleigh Convention Center , Raleigh , North Carolina , United States

Organizing Committee: Chuck Ammon, Pablo Ampuero, Colleen Dalton, Keith Koper



Global Seismology continues to advance steadily using well-established global and regional seismographic networks. Valuable and unique observations of earthquake processes will continue to be harvested from these facilities for many years to come, as will additional constraints on the seismic properties of Earth’s interior. However, a transformative advance in seismology will require an ambitious data collection effort that greatly increases the information available to explore earthquake ruptures and Earth’s interior. A large-scale effort to deploy intermediate-term seismic arrays offers an avenue for such an advance. Expanding fundamental seismological observations from ground motion at isolated points on the globe to large-aperture, broadband observations of ground motion, ground-motion gradients (beneath the arrays), and wavefield slowness provides an opportunity to increase the information available to investigate earthquakes and Earth’s interior.

The goal of this workshop is to bring together experts in global seismology and seismic array analyses to discuss the principles and current state of array seismology and explore the potential for establishing an internationally supported array of broadband seismographic arrays. Through group interaction and breakout discussions targeting key topics attendees will articulate the major scientific motivations for array studies, identify resources available and potential needs, lay the groundwork for international collaborations. A potential goal of the workshop will be to draft a white paper that can be used to drive long-term goals related to an international arrays facility.

Timing and Location

The Arrays workshop begins at noon on Wednesday May 15th, immediately after the EarthScope National Meeting, and runs through Thursday May 16th. We encourage Arrays workshop attendees to attend the EarthScope meeting as well. Early bird registration ($150 through April 5th, closes on May 6th) for the EarthScope meeting covers 2+ days of talks and poster sessions and includes all meals. The EarthScope meeting combines presentations on seismology, geodesy, and a variety of other disciplines and offers many opportunities to interact with other geoscientists. Registration for the Arrays Workshop is now closed.



The workshop will take place at the Sheraton Raleigh Hotel, which also serves as lodging for the EarthScope National Meeting. The registration deadline for rooms at the group rate is April 19th.



IRIS will provide lunch and dinner on Wednesday, May 15th and breakfast and lunch on Thursday, May 16th. There are funds available to support travel and lodging. Please contact Andy Frassetto by April 12th if you anticipate needing to utilize this financial assistance.
