MISR Aoba Volcano Plume
The Aoba volcano located on Ambae, one of the Vanuatu Island chain in the SW Pacific, began showing heightened activity on August 30, 2017. This image shows a Terra/MODIS image from Worldview taken March 16, 2018 of a Multi-Angle Imaging Spectroradiometer (MISR) observed plume reaching ~5km. Accurate plume heights are needed to determine the influence of volcanic eruptions, but are difficult to obtain due to the hazardous nature of volcanic eruptions. Stereo images from NASA's MISR make it possible to retrieve plume height in ongoing eruptions using parallax. View the MISR Active Aerosol Plume-Height (AAP) Project paper to see peak altitude and settling differences in a nearby plume emitted by the Ambrym Volcano located south of the Aoba Volcano.
