This project involves repeat street view surveys for 16 months across a broad and demographically diverse cross-section of Seattle. The data being collected will allow the team to assess: (1) the community impact of the pandemic on business operations, transportation networks, and other community assets, (2) the rate and quality of recovery following shelter-in-place, and how this varies locally based on a community's socioeconomic characteristics, and (3) the impact of shelter-in-place policy relaxation on communities following this disaster.
Grilliot deployed to Ponce, Puerto Rico in support of Principal Investigator, Arash Zaghi, and Co-PI's Alexandra Hain and Jamie Padgett's NSF funded RAPID grant to identify if the impacts of Hurricane Maria resulted in an increased level of damage or have caused unexpected modes of failure during the recent 2020 earthquake series. The team collected a comprehensive data set using standard and 360 degree geotagged photography, aerial images from a UAS, and structural scans of damaged buildings from the Leica RTC360 scanner.
Lowes, Berman, Lyda and Peltier deployed to Kobe, Japan, in support of Principal Investigator, Paulo Calvi's NSF funded research project, which is investigating the seismic performance of a full-scale three-story reinforced concrete building system. The team used an array of RAPID equipment, including the Leica RTC360 medium-range lidar scanner, Leica P50 long-range lidar scanner, Leica TS16I robotic total station, and Canon DSLR camera to collect data before and after each of the three testing events throughout the week.
The RAPID Staff worked with Jennifer Bridge's team at the NHERI UF EF to deploy the Leica P50 ScanStation for taking measurements of various configurations of the Boundary Layer Wind Tunnel (BLWT) terraformer.
Grilliot and Lyda deployed to Idaho County, ID, to conduct terrestrial, aerial, and mobile lidar surveys for agricultural research.
From October 7th to 11th, Wartman, Grilliot, Lyda and Peltier hosted a hands-on training and deployment workshop in collaboration with the During Nearshore Event eXperiment (DUNEX) at the U.S. Army's Field Research Facility in Duck, NC. They provided participants from the coastal engineering community with the opportunity to develop expertise in using RAPID equipment (z-boat, short and long-range scanners, various UAS, water level gauges, and grab sampler). Data was also gathered to support a number of research projects led by attendees.
An international collaboration between NHERI RAPID and QuakeCoRE (www.quakecore.nz) supported Lucas Hogan and Max Stephens, Assistant Professors at the University of Auckland, New Zealand, and their research to document the structural damage sustained in a modern instrumented building following the 2016 Kaikoura Earthquake. Data was collected using short-range scanners (Leica BLK360) and high-resolution cameras for structure from motion. This research is a part of a New Zealand project to improve the assessment guidelines and provide retrofit solutions for concrete buildings with precast floors, a common system damaged in the Kaikoura Earthquake.
As part of an NSF Award that supports post disaster reconnaissance, Rob Kayen, PhD, Senior Scientist at the USGS and Professor at UC Berkeley, and Alex Grant, PhD, Research Civil Engineer, traveled to Tomakomai, Hokkaido, Japan for Phase II of the GEER reconnaissance project initiated there in 2018 following the earthquake.
RAPID deployed two of its expert field technicians - Andrew Lyda and Sean Yeung - to Ridgecrest, CA following the earthquakes that occurred on July 4th and 5th. Bringing with them RAPID’s DJI Matrice 210 drones, Leica GS18T GPS Receivers, and a couple of iPads to support the GEER team already in place, they collected aerial imagery of the fault ruptures for the purpose of creating orthomosaics and DSM models.

RAPID deployed several of its field technicians, along with its Phoenix Lidar miniRanger drone system to coastal Oregon, to characterize the rate and behavior of movement for two highly-active, coastal landslides that are subject to bluff erosion.

In support of a NSF-supported GEER project, RAPID’s Jake Dafni, PhD, trained field researcher Fikret Atalay (GA Tech) on its ATOM Seismic Data Acquisition System and its Nanometrics Trillium Seismometers. Atalay performed multi-channel analysis of surface waves (MASW) surveys at several sites across Anchorage five months following the earthquake.
RAPID’s Technical Director, Michael Olsen, Associate Professor of Geomatics at Oregon State University, traveled to the Kaikoura Region of New Zealand to take part in a training offered to 24 graduate students and young professionals from around the world. Hosted by EERI and QuakeCore - New Zealand’s Centre for Earthquake Resilience - it was an opportunity for emerging leaders to gain hands-on experience, whilst using RAPID equipment, in collecting LIDAR data and tracking the evolution of landslides triggered by the 2016 earthquake. Dr. Olsen brought with him a long range scanner (Maptek I-Site XR3), survey GPS Receivers (Leica GS18T), and a few short range scanners (Leica BLK360).
On four separate deployments, from April to August, the facility sent equipment and/or field technicians to capture perishable spatial data on a series of rock slopes near Palmer, AK. The objectives were in line with the objectives of a NSF RAPID grant sponsoring research to quantify temporal changes in rockfall magnitude for well characterized slopes shaken by the 2018 Anchorage Earthquake. Equipment used included a long range scanner (Maptek I-Site LR3) and survey GPS receivers (Leica GS18T).

Sean Yeung (UW) and Jake Dafni deployed to coastal Oregon along highway 101 bringing with them the Phoenix Lidar miniRanger drone system. Collecting data for ODOT, the intent was to characterize the rate and behavior of movements for two highly-active, coastal landslides that are subject to bluff erosion.

Joining Erica Fischer’s (OSU) research team, RAPID deployed technical staff and equipment to Paradise, CA in late March to survey hospitals and schools that had been affected by the Camp Wildfire, which occurred in late 2018 and destroyed an estimated 18,800 buildings. The objective was to collect data on wildfire performance of engineered buildings, and on any effective mitigation that was performed prior to the wildfire.

Researchers from University of Washington and Auburn University traveled to the Panhandle of Florida in early November following Hurricane Michael, which made landfall in Mexico Beach, FL on October 10th. A project funded by the National Science Foundation, its primary focus was to assess the damage done to large-scale industrial buildings. The team utilized RAPID’s extensive equipment portfolio bringing with them numerous cameras (DJI Osmo, Insta360, Canon DSLR, and Flir), DJI Phantom and Matrice 210 drones, the Leica TS16 and Maptek XR3 long-range scanner.
