View of the 2018 Kīlauea caldera collapse structures from Kīlauea Overlook within Hawai‘i Volcanoes National Park. USGS photo by K. Mulliken on Sept. 2, 2020.

Still images from videos of surface water flow overlaid with velocity vectors during low (top) and high (bottom) flow conditions in Frankford Creek, Philadelphia, Pennsylvania, September 2020. These videos were processed using large-scale particle imaging velocimetry (LSPIV) to estimate streamflow in a location where standard methods are inadequate. 

The UNAVCO-operated geodetic infrastructure located in Yellowstone National Park consists of over a dozen continuously operating geodetic sites.  Most of these sites stream real-time data to the UNAVCO data center.  After the September 2020 maintenance trip, there are now 8 fully upgraded GNSS sites (red square) located in the park.

The Total Water Level and Coastal Change Forecast has continually expanded since real-time forecasts began in 2015. In 2020, new regions of the Gulf and South Atlantic coasts were added to the forecast and officially approved for use in National Weather Service Forecasts.

This Coastal Change Storm Hazard Team forecast was made at 4 AM CDT August 26, 2020 and shows forecast beach erosion at the base of the dunes (the strip of colored bars closest to the coast), overwash (middle strip) and inundation (outer strip) from Hurricane Laura.  The model accounts for sandy beaches and barrier islands and does not include marshes,
