ARIA Cross-Track Interferogram, Sulawesi Earthquake 
ARIA Cross-Track Interferogram, Sulawesi Earthquake    The Advanced Rapid Imaging and Analysis (ARIA) team at NASA's Jet Propulsion Laboratory and Caltech in Pasadena, CA created this false-color map showing deformation in Central Sulawesi, Indonesia, including the city of Palu, as a result of the Magnitude 7.5 earthquake on September 28, 2018. The map is derived from synthetic aperture radar (SAR) images from the ALOS-2 satellite, operated by Japan Aerospace Exploration Agency (JAXA). The images were taken before the earthquake on September 27, 2018 and after the earthquake on October 11, 2018.

In response to the event, the feature, "NASA Airborne Team Surveys Flooding from Hurricane Florence," was published on NASA.gov on October 4, 2018.

NASA's Black Marble Technology over Florida
The pre- and post-event images of NASA's Black Marble product suite show the artificial lights at night from Panama City, FL and Mexico Beach, FL based on data collected on October 6 and October 12, 2018. NASA's Black Marble product suite has immediate access to data documenting disruptions in energy infrastructure and utility services due to Hurricane Michael. The pre and post event images in Florida are based on the composite Black Marble images. The fine resolution images show artificial lights at night prior to and after the arrival of Hurricane Michael. Areas in high-light condition are in red and yellow, while areas in low-light condition are in blue and black. The Black Marble Level 3 and High Definition (HD) data are continuously being produced and delivered to end-users for the latest day available.

GPM IMERG rainfall accumulation from Hurricane Michael
At least eleven deaths have now been attributed to deadly hurricane Michael. Some casualties resulted not only from Michael's destructive winds and storm surges but also from the blinding rain that Michael produced as it battered states from Florida northeastward through Virginia. Today tropical storm Michael is moving out over the Atlantic Ocean and has transitioned into a powerful extratropical storm.   This animation using the GPM IMERG multi-satellite dataset shows the estimated total rainfall accumulation for #HurricaneMichael from 10/8/18 - 10/12/18. Learn more: https://t.co/aJuEp6o855 pic.twitter.com/n6e2eEw8om — NASA Precipitation (@NASARain) October 12, 2018 This rainfall accumulation analysis was derived from NASA's Integrated Multi-satellitE Retrievals data (IMERG). IMERG data were used to calculate estimates of precipitation totals from a combination of space-borne passive microwave sensors, including the GMI microwave sensor on the GPM satellite, and geostationary IR (infrared) data. IMERG data benefits from algorithms developed by NASA's Precipitation Measurement Missions (PMM) science team that supports GPM's Missions. This analysis shows IMERG rainfall accumulation estimates along Michael's track during the period from becoming a tropical depression fourteen off the coast of the Yucatan Peninsula until it passed off the East Coast. Michael's approximate 0000Z and 1200Z locations are shown overlaid on this analysis. IMERG rainfall accumulation data indicated that Michael frequently produced rainfall totals greater than 10 inches (254 mm) along it's track. IMERG data indicated that the heaviest rainfall accumulation occurred off the Yucatan where were over 20 inches (512 mm) were estimated. Also of interest is the heavy rainfall that fell in less than a week with stormy weather extending from Texas to the Great Lakes.

On October 10, 2018, the Advanced Microwave Scanning Radiometer 2 (AMSR2) instrument, onboard JAXA's GCOM-W1 satellite, observed the surface precipitation rates of Hurricane Michael as it approached the United States.
On October 10, 2018, the Advanced Microwave Scanning Radiometer 2 (AMSR2) instrument, onboard JAXA's GCOM-W1 satellite, observed the surface precipitation rates of Hurricane Michael as it approached the United States. This LANCE NRT AMSR2 image shows high precipitation rates in red, yellow and light blue, and lower rates in dark blue and purple. LANCE NRT AMSR2 products include surface precipitation rate, wind speed over ocean, water vapor over ocean and cloud liquid water over ocean. NRT AMSR2 products are generated within three hours of observation, using algorithms provided by the NASA-funded US AMSR2 Science Team, with JAXA NRT L1R (resampled brightness temperatures) as input.

GFMS Inundation Estimate Hurricane Michael
Inundation Estimate from Global Flood Monitoring System (GFMS) based on surface and river routing models using NASA Global Precipitation Measurement (GPM) Integrated Multi-Satellite Retrievals for GPM (IMERG) precipitation information. GFMS covers the globe from 50N-50S. This product shows the near real time flooding every 3 hours at 1 km resolution. This product can be used to estimate flood extent (and depth) and for comparison with other estimates from satellite and ground observations.

Sentinel-1 Water Extent Imagery
Using data collected from the European Space Agency's (ESA) Sentinel-1B satellite, scientists at NASA's Marshall Space Flight Center (MSFC) are able to create maps of the extent of water due to the effects of Hurricane Michael. The synthetic aperture radar (SAR) aboard Sentinel-1B allows for the detection of water on the surface when clouds are present as well as during the night time hours. This product shows three areas: known reference water (blue), anomalous water identified outside the known reference water areas (red), and water detected in known wetlands or barren land (tan). The areas in red would be the likely flood waters due to the effects of Hurricane Michael.

USGS/NASA Landsat 8 Imagery Hurricane Michael
The True Color RGB composite provides a product of how the surface would look to the naked eye from space. The RGB is created using the red, green, and blue channels of the respective instrument. This product contains pre-event images from September 15, 22, 24, 29 and October 6, 2018. The True Color RGB is produced using the 3 visible wavelength bands (red, green, and blue) from the respective sensor. Some minor atmospheric corrections have occurred. Image produced on 9/26/2018.

Sentinel-1 RGB Imagery from Hurricane Michael
The Alaska Satellite Facility has developed a false color Red, Green, Blue (RGB) composite image of the Sentinel 1A/B Synthetic Aperture Radar (SAR) instrument which assigns the co- and cross-polarization information to a channel in the RGB composite. When used to support a flooding event, areas in blue denotes water present at the time of the satellite overpass prior to the landfall of Hurricane Michael. This product shows three areas: known reference water (blue), anomalous water identified outside the known reference water areas (red), and water detected in known wetlands or barren land (tan). The areas in red would be the likely flood waters due to the effects of Hurricane Michael.
