Using @NASA satellites to track and measure the plume at #Kilauea:

One of the most noticeable and dramatic aspects of an effusive volcanic eruption —such as the one happening at Hawaii’s Kilauea—is the hot, molten rock that flows from vents in Earth’s surface. But lava is just one part of the eruption. Volcanoes also emit plumes of gases and particles from active vents. Since plumes can disperse over vast areas, satellites are particularly useful for monitoring them. For instance, the Multi-angle Imaging Spectroradiometer (MISR) sensor on NASA’s Terra satellite acquires stereo images that can be used to measure the height of volcanic plumes. It can also make observations of the shape, size, and light-absorbing properties of tiny particles (aerosols ) found within plumes. Though Kilauea has been erupting continuously since 1983 , the eruption took a dangerous turn on May 3, 2018, when several new fissure eruptions emerged in a residential ...
