SSA invited members of the public to a town hall meeting on earthquake early warning systems in the Pacific Northwest. A panel of EEW experts were on hand to explain how they function, how they can prevent damage and injury and when they plan on being implemented throughout the region.


  • Sandi Doughton, Seattle Times science reporter and author of Full-Rip 9.0: The Next Big Earthquake in the Pacific Northwest.
  • Scott Miles, an expert in disaster risk reduction in the Department of Human Centered Design and Engineering at the University of Washington.
  • Michele Campbell, ShakeAlert program manager at RH2 Engineering.
  • Harold Tobin, director of the Pacific Northwest Seismic Network (PNSN) at the University of Washington.
  • Doug Toomey, co-director of the PNSN at the University of Oregon.

Women in Seismology Reception

Gail Atkinson, Professor of Geophysics at Western University, delivered the opening remarks at this popular event for women in seismology to connect, talk about their experiences and network.

Mentoring Breakfast for Early-Career and Student Attendees

Thursday, 25 April, 7:00–8:15 a.m.

Student and early-career members got together with professional seismologists to ask questions, discuss their research and network in this social breakfast.

Field Trips

The 2019 SSA Annual Meeting offered three exciting field trips.

Cascadia Earthquakes by Canoe

Saturday, 27 April 2019
8:00 a.m.–10:00 p.m.

Hardy participants viewed iconic clues to great earthquakes on the Cascadia subduction thrust. The clues tell of recurrent subsidence and associated tsunamis in the past 2,000 years. Highlights include one of the estuarine ghost forests that identifies Cascadia as the likely source of a Pacific Ocean tsunami in January 1700, and which provides tree-ring evidence for an unusually long recurrence interval before then.

Trip leader: Brian Atwater (scientist emeritus, U.S. Geological Survey)

Earthquake Geology of Seattle

Saturday, 27 April 2019
8:30 a.m.–6:30 p.m.

This trip explored the geomorphology and stratigraphy of Seattle that record the history of crustal faulting and determine site response to earthquakes on all sources. Destinations included the South Beach of Discovery Park, scenic Jose Rizal Park, historic Alki Point, Terminal 107 Park and the Diagonal Avenue South Public Shoreline.

Trip Leaders: Ralph Haugerud (U.S. Geological Survey), Elizabeth Barnett (Shannon & Wilson, Inc.), Bill Laprade (Shannon & Wilson, Inc.) and Elizabeth Davis (University of Washington).

Facilities Tour of University of Washington

Saturday, 27 April 2019
7:00–11:00 a.m.

A tour of the University of Washington campus and its seismic research facilities, including the Pacific Northwest Seismic Network (PNSN), the Rapid Response Research Facility and UW Oceanography’s newest research vessel, the Rachel Carson.

Trip Leader: Ian Stone (University of Washington)


The 2019 SSA Annual Meeting features five hands-on workshops on Tuesday, 23 April, made possible with support from the Kanamori Fund. All workshops start at 1 p.m. Pacific.

Sign up for any of the workshops when you register for the Annual Meeting.

Achieve Your Career Goals

Tuesday, 23 April 2019, 1:00–4:00 p.m.

This three-hour workshop focused on strategies and tactics to understand what you can, could and should be doing for your career. Topics include how to conduct a job search in academia, consulting or government agencies; the pros and cons of working in each sector; how potential employers find job seekers and other career-related questions.

Instructor: Alaina Levine, Quantum Success Solutions

Developing and Visualizing Community Seismic Velocity Models

Tuesday, 23 April 2019, 1:00 p.m.–4:30 p.m.

This workshop discussed the challenges and best practices for developing and maintaining community velocity models, as well as explore software and tools for visualizing 3-D models.

Instructors: Erin Wirth, U.S. Geological Survey; Philip Maechling, Southern California Earthquake Center; Manoch Bahavar, Incorporated Research Institutions for Seismology

Getting Published – Writing a Good Scientific Paper
