CRESCENT Topical Workshop

CRESCENT Community Velocity Model Validation Workshop

April 19, 2027
Seattle, WA

Workshop Goals

The output of physics-based ground motion simulations, earthquake relocations, and a number of other applications, depend heavily on the accuracy of seismic velocity models. In particular, if physics-based ground motion simulations are to be used towards seismic hazard assessment in the Cascadia Subduction Zone, they will require validation to assess their accuracy in predicting ground motion intensities.

This workshop will showcase existing efforts towards validation of the CRESCENT CVM, upcoming CVM updates, and host discussions of key needs and implications of validation work.

EMU, University of Oregon, Eugene, OR

Venue

This CRESCENT Topical Workshop will be held at the University of Oregon, in the Gumwood Room on the 2nd Floor of the Erb Memorial Union Building (EMU) located at 1395 University Street, Eugene, OR 97403

Local information

The EMU is located at the heart of the University of Oregon campus, within easy reach of downtown Eugene and surrounding places of interest. Click here for information on where to eat, drink and recreate, or check this map for more ideas.

Flights and ground transportation

Eugene airport (EUG) is a ~20 minute drive from the meeting venue. There is no public transportation from the airport to the university, though several taxi, shuttle and rideshare options are available.

Parking

The University of Oregon has two main parking garages that are an eight-minute walk from the workshop venue: 13th St Garage and Millrace Drive Garage. Daily visitor permits for other campus lots, including ADA parking spaces, are available via the University’s parking portal.

Lodging

CRESCENT has selected the Residence Inn by Marriott Eugene Springfield as the host hotel. Located 1.6 miles from the meeting venue, the hotel is conveniently located near restaurants and a multi-use path leading to UO campus. Here is a trail map from the hotel to the EMU. PeaceHealth Rides has a couple of bike share hubs near the hotel. Lyft and UBER are also available in the Eugene area.

The Hayward Inn and Best Western New Oregon are other hotel options with less than a 10-minute walk from the venue.
