Replying to @davepetley
Thanks for sharing this @davepetley. Using @HazMapper #GEE app, two more peat landslides in the vicinity are visible, likely triggered around the same time as the one you highlight in the AGU blog post. HazMapper URL = cmscheip.users.earthengine.a…;
Red areas = decrease in NDVI following landslides (peat slides) on the west-northwest flank of Benbrack, County Cavan, Ireland as identified with the HazMapper Google Earth Engine application using a 2-week pre-post analysis window of Sentinel-2 satellite imagery centered on July 4, 2021.

In January, debris flows above the #ColumbiaRiverGorge blocked I-84 east of #Portland, OR. Because it was winter, #NDVI change detection is challenging and it took a few months, but the events are now clearly visible (reds) using the HazMapper #EarthEngine app.

#Popocatépetl debris flows (reds in the figure below) triggered by Mw7.1 Sept 19, 2017, Puebla-Morelos EQ are quite visible with a 12-month pre-post analysis using #rdNDVI metric in @HazMapper. Direct HazMapper URL = cmscheip.users.earthengine.a…;
Debris flows triggered by September 19, 2017 Mw 7.1 Earthquake on west flank Volcan Popocatépetl, Mexico. Debris flows are red areas, that represent the loss of vegetation (decrease in NDVI) resulting from the event.

Have you heard of @HazMapper? Faculty Fellow @KarlWegmann and PhD student Corey Scheip have developed a #GoogleEarthEngine application that enables #opensource mapping of global hazards like #tornadoes #landslides and more. Check it out: hazmapper.org/
