"Restless Kilauea" -- Imagery from Copernicus Sentinel-2, ESA
Kilauea has been undergoing increased activity since earthquakes began at the beginning of May, 2018, leading to major eruptions beginning on the 17th of May, according to USGS. The European Space Agency (ESA) Sentinel-2 satellites have been tracking visible-spectrum macro-scale changes in the lava flow on the eastern flank of the Big Island of Hawaii. The earthquakes beginning on May 3rd opened fissures to the northeast of the main caldera of Kilauea. The opening of these fissures led to a drop in lava levels. In the main caldera, this has led to the formation of a lava created by the crumbling crater walls and groundwater seeping into the crater and cooling the lava below its melting point. This cap re-pressurized the magma chamber, forcing lava out of the newly-formed fissures to the east and northeast of the Kilauea Caldera. The GIF below shows the changes in the lava flows as the various fissures in the area have opened and closed from May 23rd to June 12th. The steam caused by the flow of lava into the ocean heavily obscures the two images taken in June.
