June 2021 #DebrisFlow and flooding near Santa Rosa de Osos, Antioquia, #Columbia. Red colors show vegetation loss due to transport and deposition of material on debris fan where the village is situated. #NaturalHazards #GEE #sentinel2

HazMapper #NDVI change-detection result for the ongoing March #wildfires in central #Texas that are part of the #EastlandComplex. Fires are located between the cities of Cross Plains and Gorman. Warm colors = vegetation loss due to fire activity. InciWeb Texas Division of Emergency Management

Another large fire in New Mexico, this time the 100,000+ acre combined #CalfCanyonFire and #HermitsPeakFire, seen here as of April 28th #rdNDVI vegetation change map (reds = veg loss due to fire).

Check out the HazMapper pre-post GIF of the August 7, 2021, rainfall-induced landslide on Mt. Silabaku, Taiwan, and the resulting debris flow along the Yusui Stream. Inspiration from the new paper in the journal #Landslides by Che-Ming Yang and coauthors doi.org/10.1007/s10346…

When you’re trying to find the location of a vaguely described landslide and HazMapper comes to the rescue to find it. Recent landslide in Quebec.

Lots of #debrisflows initiating on the high topography around Emamzadeh Davod last week. A cloud is right over town in the latest #Sentinal2 image but still can see the track via link below. You'll see many more panning to the NW cmscheip.users.earthengine.app/view/hazmapper…;

The rdNDVI metric is also useful for identifying vegetative stress from #flooding. Very cool to see researchers implement HazMapper for a flooding study in Afghanistan! Recent article from Atefi and Miura. Good stuff!! researchgate.net/publication/36…

A quick comparison of mapping landslides (August 2021 Nippes EQ in #Haiti) in the original HazMapper compared to the beta v1.1 which includes moving from TOA to SR Sentinel data and some additional cloud filtering techniques. #googleearthengine #gee #bigdata #naturalhazards

HazMapper Wow! That's awesome! Here's a comparison of the output with rainfall-induced landslides in Nelson, NZ earlier this year. I see there's a download link, but do you plan to add a direct WMS server (or similar) option for QGIS / Arc? static.geonet.org.nz/info/reports/l…

For those following the Oct 8-9 Las Tejerías landslide disaster in Venezuela, the HazMapper +rdNDVI output clearly shows the shallow landslides and debris flows. Explore in HazMapper at cmscheip.users.earthengine.app/view/hazmapper…; and see Dave Petley blog post-blogs.agu.org/landslideblog/…

October flood woes along the #Niger and #Benue Rivers is clearly visible using #Sentinel2 imagery and the HazMapper #rdNDVI algorithm. Contiguous red areas = loss of vegetation during #NigeriaFloods inundation. Explore yourself with the direct URL at cmscheip.users.earthengine.app/view/hazmapper…;
