<br>
Activation date: 2021-08-19 <br>
Event type: Storm <br>
<br>
Activation reason: <br>
The CEMS Risk and Recovery Mapping (Standard) has been activated to assess the effects of the Eta and Iota hurricanes that hit Central America starting from the beginning of November 2020.Eta affected 4 million people across Central America, with widespread flooding, destructive winds, and devastating landslides. Weeks after, starting from 16th November 2020, Iota struck the region with even more intense weather that worsened the conditions. Heavy rainfall associated with Iota was reported also in Guatemala in a 6-hour period on 18th November.This RRM activation was requested with the aim of calculating the effective impacted areas, exposed population, economic losses and livelihoods, change of land use and help in reconstruction and recovery actions.Particularly, this RRM activation provides the STANDARD products Flood delineation (P04), with related Impact assessment on assets and population (P14), for an area of interest surrounding Sesajal (243km²).ResultsThe results of the activation provide a set of flood delineation (P04) products based on Sentinel-1 data, acquired after either Eta or Iota cyclone on the 10.11.2020, 16.11.2020, 22.11.2020 and 28.11.2020 (geodata available at Downloads). P04 products are associated with an estimation of the corresponding water depth (raster files available at Download).Example of P04-Flood delineation production over AOI01 Sesajal (situation as of 28.11.2020)The Impact assessment analysis on assets and population (P14) is based on the available reference datasets (i.e. OSM), the flood extent provided by P04, and WorldPop (2020) population data. The impact was assessed on the cumulated flooded areas basis. Summary tables are available at Downloads. <br>
