Using ~ 1 m resolution imagery collected between 2000 and 2010, the U.S. Geological Survey (USGS) National Civil Applications Center (NCAC) monitored dramatic changes at East Timbalier Island, a Gulf of Mexico barrier island located on the west side of the Mississippi River Delta (Thomas et. al, 2011). The imagery was collected by US National Imagery Systems (USNIS) and archived at the USGS Global Fiducials Library (GFL). New research expands this study both retrospectively and prospectively using declassified imagery collected in 1962 and 1972; Landsat imagery collected since 1972; aerial photography collected since 1953; and 1991-2020 GFL imagery.

The 2018 lower East Rift Zone eruption of Kīlauea Volcano began in the late afternoon of 3 May, with fissure 1 opening and erupting lava onto Mohala Street in the Leilani Estates subdivision, part of the lower Puna District of the Island of Hawaiʻi. For the first week of the eruption, relatively viscous lava flowed only within a kilometer (0.6 miles) of the fissures within Leilani Estates, before activity shifted downrift (east-northeast) and out of the subdivision during mid-May. Around 18 May, activity along the lower East Rift Zone intensified, and fluid lava erupting at higher effusion rates from the downrift fissures reached the ocean within two days. Near the end of May, this more vigorous activity shifted...
