High-resolution chirp sub-bottom data were collected by the U.S. Geological Survey and the University of Washington in February of 2017 west of Seattle in Puget Sound and in Lake Washington, Washington. Data were collected aboard the University of Washington’s R/V Clifford A. Barnes during USGS field activity 2017-612-FA using an Edgetech SB-512i sub-bottom profiler. Sub-bottom acoustic penetration spans several tens of meters and is variable by location.

The U.S. Geological Survey, with funding from the National Earthquakes Hazard Reduction Program, collected ~24 km of north-south trending land-based P-wave seismic reflection profiles gathered across three urban areas in Seattle, Washington: West Seattle, central Seattle, and Mercer Island. The West Seattle profiles were collected with an accelerated weight drop source and 8 Hz vertical component geophone sensors at 5 m spacing along 47th Ave, 44th Ave, 42nd Ave, 39th Ave, and Walnut Ave. The central Seattle profiles were collected with a Minivib I source and 8 Hz vertical component geophone sensors at 5 m spacing along 13th St and Beacon Way. The Mercer Island profiles were collected with a Minivib III source and...

High-resolution multichannel minisparker seismic-reflection data were collected by the U.S. Geological Survey and the University of Washington in February of 2017 west of Seattle in Puget Sound and in Lake Washington, Washington. Data were collected aboard University of Washington’s R/V Clifford A. Barnes during USGS field activity 2017-612-FA using a 500 Joule SIG 2-mille minisparker sound source and recorded on a 48 channel Geometrics digital hydrophone streamer. Sub-bottom acoustic penetration spans several hundreds of meters and is variable by location.
