2019 UNAVCO Highlights


Title Date
RAPID Response to the November 30, 2018 M 7.0 Earthquake 13 km N of Anchorage, Alaska

On November 30, 2018 a magnitude 7 earthquake struck just north of Anchorage, Alaska and caused over $75 million in damage to private and public facilities. The earthquake took place in the upper part of a subducting slab where the slab may be bending downwards, and early indications suggest that the event was related to stresses caused by this plate bending.

Reviving a Site Just out of Reach: P438

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 boat or helicopter.

Data Event Response to the October 15, 2019 M 4.5 Earthquake 1km SSE of Pleasant Hill, California

A magnitude 4.5 earthquake occurred at 05:33:42 UTC on October 15, 2019, 1km SSE of Pleasant Hill, California. For more information, see the USGS Earthquake Hazards Program event page. The event occured within the Network of the Americas (NOTA) footprint. NOTA is a core component of the NSF Geodetic Facility for the Advancement of Geoscience (GAGE), operated by UNAVCO.

The 2019 SAGE/GAGE Workshop

Our understanding of fundamental Earth processes requires multifaceted investigations that span a large range of temporal and spatial scales. This workshop will focus on cutting edge geophysical results of processes in the solid earth, cryosphere, oceans and atmosphere and will highlight synergies between the SAGE and GAGE communities.

Community Event Response to the July 4, 2019 M 6.4 and July 6, 2019 M 7.1 Earthquakes Near Ridgecrest, California

Signals from this event were recorded by 12 GPS/GNSS stations within 71 km of the epicenter operated by UNAVCO that were streaming high rate (1-sps / 1 Hz) data in real time (Figure 2). These data allowed peak ground displacements (PGD) to be calculated automatically from the displacement traces within seconds of the earthquake (Figures 3 and 4).

Data Event Response to the June 26, 2019 M6.2 Earthquake 5km SE of Aserrio de Gariche, Panama

UNAVCO is downloading high-rate 1-sps (1 Hz) data from the few NOTA GPS/GNSS stations near the epicenter of this event. In addition, 5-sps (5 Hz) data are being downloaded from available sites. Due to the remote locations and limited comms of these sites, data will take longer than usual to be acquired. A station map is shown in Figure 2; this map will be updated after data are acquired. When downloaded, these data are available from the UNAVCO high rate data ftp site.

The Myrtle Grove Subsidence Superstation

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 a coastal marsh—in which the installation team would sink up to their hips in mud and water.

Final Celebration of the Successes of EarthScope

Scientists, community members, National Science Foundation (NSF) staff and representatives of federal agencies gathered in Washington, D.C. May 21-22 to celebrate the successes of EarthScope. EarthScope was an NSF program designed to study the structure and evolution of the North American continent and the processes that cause earthquakes and volcanic eruptions.

Accessible Earth: Innovative Field Course Increases Options and Accessibility to Geoscience Current trends in US demographics, rising costs of higher education, and hurdles to entry and retention of first-generation students seriously threaten our ability to mitigate future workforce shortages across STEM fields, with geosciences among the least diverse and most at risk. At the same time, it is widely recognized that the geoscience curriculum must be modernized to better prepare the next generation to utilize geoscience data streams to maximally benefit society and ensure a sustainable future.

Studying a Moving Target: Tracking Cryoconite Holes on Canada Glacier Researchers from University of Colorado and Portland State University are using cryoconite holes on Canada Glacier, located in the McMurdo Dry Valleys, to study microbial communities in their natural environment. Cryoconite holes start as small, dirt-filled depressions on the ice surface that melt into the ice, creating a pool of water capped by ice. Within the water, microbial life thrive in summer despite being isolated from the atmosphere and frozen every winter.
