Project Overview Fieldwork in Nicaragua conducted in early February 2020 supported three different projects funded by NSF and NASA, as noted above. The work involved setting up GPS equipment for campaign surveys (eGPS), installing new campaign monuments, repairing continuous GPS stations (cGPS), installing a new cGPS station, installing a gas sensor on Masaya volcano, UAS … Continued
Project Overview The Lake Agnes rock glacier dominates the Lake Agnes cirque, near Cameron Pass in northern Colorado, however, little is known about its kinematics or dynamics. To determine the motion of the rock glacier, UNAVCO supported Colorado State University researchers with two sets of tools that were used simultaneously: terrestrial laser scanning (TLS) and … Continued
Project Overview From the NSF award abstractThe great earthquakes and tsunamis of 2004 (Sumatra) and 2011 (Japan) were wake-up calls that our forecasting skill for these catastrophic events remains poor. Measurement of the slow motions of the Earth’s surface near active faults could help to forecast the location and the size of future earthquakes. This … Continued
Trinidad and Tobago Neotectonics and Seismic Hazard from Geodesy Overview The rich and varied landscapes and geology of Trinidad and Tobago, a twin-island nation in the southeast Caribbean, reflect a complex, multi-phase tectonic history. Trinidad-Tobago makes up the eastern part of the southern Caribbean orogen, a range of coastal collisional mountains that rim northern South … Continued
Overview GPS/GNSS station P438 is located on Northwest Island, a small uninhabited island adjacent to Fidalgo Island in the Puget Sound. The site is in a prime location to capture episodic tremor and slip data and monitor ongoing plate deformation in the Cascadia subduction zone. Yet site access is tricky: P438 is only accessible via … Continued
Delta Sites How do you install a GPS station in a marsh? How about three all in the same place? Installation of the Myrtle Grove subsidence superstation began in August 2016, but planning began well beforehand. The array of three co-located stations in Myrtle Grove, Louisiana, posed particular challenges, as the instruments were installed in … Continued
Summary of Work Continuing previous work in Bangladesh, Michael Steckler (LDEO) and Keith Williams (UNAVCO) arrived back in Myanmar in late October of 2018 to begin the installation of five additional cGPS sites with collaborators. The larger project entails installation of a transect of cGPS stations and seismometers spanning Bangladesh, India, and Myanmar (see previous Tripartite … Continued

Project Overview POLENET, a multiyear NSF-funded project, has entered its third award phase. The team for the 2018-19 Antarctic season, composed of six people, left McMurdo station for the remote field camp of WAIS Divide on December 13th, 2018. During the six-week deployment, the team installed five new GPS stations on the coast of Marie … Continued
CHORDS Provides Next Generation Infrastructure for Real-time Geoscience Data Services Overview The EarthCube Cloud-Hosted Real-time Data Services for the Geosciences (CHORDS) project aims to simplify access to real-time geoscience data. Through CHORDS portals, scientists can visualize data streams: (1) in samples/min/hour/day, (2) as simple time-series, and (3) via the time-series visualization software Grafana for real-time … Continued
