CRESCENT Topical Workshop

Cascading Hazards Workshop

March 6, 2025, 6:00 pm, Opening Dinner + March 7, 2025, 8:30 am – 5:00 pm, Hatfield Marine Science Center, Newport, OR

Workshop Goals

Cascading Hazards: Understanding Ground Failure in Cascadia

Shallow subsurface properties in the Pacific Northwest not only influence the characteristics of ground shaking from large earthquakes, but also control coseismic cascading hazards, e.g., landslides, liquefaction, lateral spreading and ground failure. Quantifying these subsurface properties is critical owing to the extensive alluvial deposits, unstable mountainous terrain, and significant precipitation in the region.

This interdisciplinary workshop will bring together researchers and practitioners concerned with shallow seismic hazards and landslides, liquefaction and ground failure impacts in Cascadia. This workshop will inform the efforts of related CRESCENT Working Groups to deliver societally relevant products.

Venue

This CRESCENT Topical Workshop was held at the Hatfield Marine Science Center on March 7, 2025.

Flights, ground transportation and parking

Hatfield Marine Science Center is about 2.5 hours (135) miles from the city of Portland and close to three hours away from Portland International Airport (PDX). Hatfield is also a little over one hour away from Oregon State University’s main campus in Corvallis.

Enterprise Rent-A-Car has an office in Newport, and it is located just a few minutes from Hatfield. Cab services are limited within Newport, but the Yaquina Cab Company serves as an option.

For maps, directions, parking and other ground transportation information, see here.

Lodging

Newport is home to various lodging choices – many are within a mile of Hatfield.

La Quinta (45 South East 32nd St., Newport, OR, 97365) is CRESCENT’s host hotel for overnight guests. La Quinta offers a hot complimentary breakfast including sausage, eggs, bacon and all the other standard continental items. The pool, hot tub, and fitness facility are open 24 hours a day for adults.
