Description
Activation date: 2021-03-12
Event type: Mass movement
Activation reason:
A storm brought strong winds and heavy rain to parts of the Portuguese island of Madeira on 25 December 2020 . Flooding and landslides were reported in the municipality of São Vicente. Local media reported 20 people were evacuated in Ponta Delgada and 7 in Boaventura. One house was destroyed and several others severely damaged. Dozens of roads were closed, leaving some areas isolated, and power lines were downed leaving many residents without electricity. Several areas recorded more than 100 mm of rain in 24 hours to 25 December 2020, with the highest total seen in Porto Moniz which recorded 161 mm of rain. The goal of the activation is to get a more accurate picture of the mass movements induced by the heavy rainfalls that occurred over the period ranging from 25/12/2020 to 08/01/2021, for an area of interest located over Santana and its surroundings.Proposed solution and resultsA pre-event reference dataset (P02.1) and a post-event LULC-CLC (P03.2) produced by mean of visual interpretation.P02.1 Reference dataset (1:5,000)P03.2 LULC-CLC @ 1:25,000 UpdateA detailed damage assessment (P08.1) by and a reconstruction monitoring (P09) performed by photo-interpretation of VHR satellite imagery acquired on the 10.02.2021 and 18.04.2021 respectively.A post-disaster landslide risk assessment (P17) based on P03.2.P17 Landslide risk assessmentPopulation exposure to landslide (P14)An Impact assessment analysis on assets and population (P14) performed with P08.1 results and WorldPop (2020) population data. In addition, an exposure analysis on assets and population is produced regarding the landslide hazard provided by P17.A Digital Surface Model based on optical VHR data has been generated from post-event tri-stereo VHR satellite imagery acquired on the 18.08.2021.Digital Surface Model (P01.1)
