Volcanoes

Overview

Volcanic ash can damage aircraft and disrupt air traffic. Agencies around the world track volcanic clouds and issue alerts to the aviation community. Now data from NASA earth-observing satellites is improving the ability to detect and forecast the hazard to aviation from volcanic clouds.

ISS Georeferenced Digital Camera Images of Kilauea Eruptive Activity 2018
This collection of visible-wavelength (RGB) digital camera images was taken by astronauts onboard the International Space Station at various times on May 6, 12, and 13 2018, then manually georeferenced by members of the Earth Science and Remote Sensing Unit at NASA Johnson Space Center. The images provide regional context, and may be useful for visualization of the ongoing event. Higher spatial resolution images may be suitable for spatial analysis to...

Data from the the Ozone Mapping Profiler Suite (OMPS) sensor on the Suomi NPP satellite, acquired April 30 - May 5, 2018
Data from the the Ozone Mapping Profiler Suite (OMPS) sensor on the Suomi NPP satellite, acquired April 30 - May 5, 2018 Kilauea has been erupting continuously since 1983, but in late April and early May 2018 the volcanic eruption took a dangerous new turn. During the last week of April, the lava lake at Halema‘uma‘u Overlook crater ...

ASTER image acquired May 6 picks up hotspots on the thermal infrared bands – shown in yellow. These hotspots are newly formed fissures and lava flows.
ASTER image acquired May 6 picks up hotspots on the thermal infrared bands – shown in yellow. These hotspots are newly formed fissures and lava flows. Credits: NASA/METI/AIST/Japan Space Systems, and U.S./Japan ASTER Science Team The eruption of Kilauea Volcano on the island of Hawaii triggered a number of gas- and lava-oozing fissures in the East Rift Zone of the volcano. The fissures and high levels of sulfur dioxide gas prompted evacuations in the area. Images taken from the Advanced...

Sentinel 1B 12-day interferogram: April 23, 2018, 4:15 p.m. UTC to May 5, 2018, 4:15 p.m. UTC
Sentinel 1B image from May 5th, 2018. Sentinel 1B 12-day interferogram: April 23, 2018, 4:15 p.m. UTC to May 5, 2018, 4:15 p.m. UTC The ESA Sentinal 1 mission has produced a series of interferograms for the recent volcanic eruption and earthquake that have occurred at the Kilauea volcano on...

Brightness Temperature Difference-based detection of sulfur dioxide (SO2).  The larger (absolute value) differences suggest larger quantities of SO2.
Examples of Ambae data products from the AIRS Rapid Response Website at JPL.  This site, currently under development, contains data products generated automatically for AIRS granules, or scenes.   The AIRS Rapid Response products may be used to track the dispersion of SO2 (Image 1) and ash clouds (Image 2) following an explosive volcanic eruption. The cloud cover product (Image 3) is an aid to interpreting the SO2 and ash detection products. The cloud cover was dense, with a tropical cyclone developing off the coast of Australia. The apparent lack of ash, relative to the presence...

Ozone Monitoring Instrument (OMI) on EOS Aura satellite measures ~0.12 Tg  SO2 emission from Aoba (Vanuatu) volcanic eruption
This volcanic SO2 plume data from the Aoba volcano (Vanuatu) explosive eruption on April 5 2018 was retrieved using the Ozone monitoring Instrument (OMI) operational Principal Component Analysis (PCA) algorithm (OMSO2) on April 6. Volcanic SO2 measured by satellite UV sensors allows tracking fast movements of volcanic ash clouds , which present hazard to aviation. In large explosive eruptions volcanic SO2 can be injected directly into lower stratosphere where it...

Mt. Fuego eruption
  It is one of Central America’s most active volcanos. Volcán de Fuego puffs continuously without notice by nearby communities, punctuated by episodes with explosive activity, huge ash plumes, and lava flows. The Guatemalan volcano is at it again, beginning its latest bout of unruly behavior on January 31, 2018. On the next day, the Operational Land Imager (OLI) on Landsat 8...

MODIS True Color Terra Image
Imagery Acquired November 27, 2017 This RGB image from MODIS/Terra on November, 27th shows the presence of ash vented out from the Agung volcano as gray and brownish areas above clouds and/or water. This contrasts with the whiter clouds on the left side of the image.

SO2 emission map
Acquried November 29, 2017 Figure 1 shows volcanic sulfur dioxide (VSO2) plume emitted from the eruption of Mt. Agung (Bali, Indonesia) and first captured by Aura/OMI and SNPP/OMPS UV spectrometers afternoon overpasses on November 26 2017, just hours after the beginning of the explosive magmatic phase of the eruption. The data show total SO2 column amounts in Dobson Units (1 DU = 2.69 1016 molecules SO2 per cm2). Background SO2 concentrations in this location are undetectable from space,...

The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this image on January 3, 2017.
The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this image on January 3, 2017. It was loud and brief. For a few minutes around 9 p.m. on January 3, 2017, Alaska’s Bogoslof volcano let loose an explosion. According to the Alaska Volcano Observatory, cloud-top temperatures indicate the volcanic plume may have reached as high as...

The Moderate Resolution Imaging Spectroradiometer (MODIS) instruments on NASA’s Terra and Aqua satellites acquired this image of the ash plume at 11:45 a.m. Alaska time (21:45 Universal Time) on March 28, 2016.
The Moderate Resolution Imaging Spectroradiometer (MODIS) instruments on NASA’s Terra and Aqua satellites acquired this image of the ash plume at 11:45 a.m. Alaska time (21:45 Universal Time) on March 28, 2016. In late March 2016, Pavlof volcano on the Alaskan Peninsula began erupting again for the first time since November 2014. Alaska’s most active volcano has erupted six times since 1996 and 21 times in the past 50 years....
