La Palma volcano lava flow


Officially published by ESA on October 1st, the raw image (2021-09-30) is already available at Google-Earth-Engine, where you can manipulate with a simple code  filters and thresholds for edge detection. In this demo we used a true color background shifted to reds, and a Normalized-Difference (B4 red, B11 SWIR 1) index for the lava flow.

Check the code here.

What  a tough year for Argentina, but let me emphasize a few issues for optimism: We´ve been awarded three projects from CFI, FITBA and CIC Buenos Aires public institutions, the first one to design upstream water retention schemes, the second one to include AI on the Azul EWS and the third one to propose drainage and retention soft structures at a plain parcel in direct coordination with the owners, all are measures to gain flood resilience.  Lorena La Macchia MSc thesis dissertation was awarded as the best contribution related to Cartography, Geodesy and Geographic Information in 2024, by the Panamerican Institute for Geography and History .

Two factors: extreme precipitations (convective cells) and the incapability of the ground/drainage systems to  handle such heavy rainfalls in a short period of time. It´s not the first time, neither the last,  and is still hardly to predict both the focus location and the flash flood evolution. Learning to Live with Risk for each municipality continues as the most reasonable policy, considering that long term climate projections are worse. My condolences for almost one hundred casualties at the moment. Satellite image from RTVE live and ALSOSpace over Valencia. EU-Copernicus Emergency Service Link    for mapping damage extents.
