Dithwa Cyclone 2025 – Sri Lanka | Medical Camps & Boat Rescue Operations

From 2025-11-26 to 2025-12-03, the Disaster Management Unit (DMU) and Emergency Operations Centre (EOC) actively responded to the Dithwa Cyclone 2025. Our Sarvodaya Boat Rescue teams assisted affected communities using boats and organized medical camps to provide timely healthcare support.

This map analyzes flood-affected areas along the Kelani River in Colombo and visualizes the locations of boat rescue operations and medical camps, using ArcGIS 10.8 basemap layers for accurate spatial representation. It highlights our humanitarian response efforts during the cyclone and provides a clear overview of relief operations.

Dithwa Cyclone 2025 – Sri Lanka | Affected Sarvodaya Societies by District

This map visualizes the district-wise impact of the Dithwa Cyclone 2025 on Sarvodaya societies across Sri Lanka. Data is based on official records from the Sri Lanka Disaster Management Centre (DMC), using the Situation Report issued on 2025-12-17.
🔗 DMC Report:https://www.dmc.gov.lk/images/dmcreports/Situation_Report_at_1600hrs_on_2025__1765970343.pdf

Raw Excel data was merged with Sri Lanka district polygon shapefiles sourced from OpenStreetMap (OSM). Analysis was conducted using ArcGIS 10.8 and ArcGIS Pro licensed applications. Attribute joins were performed by matching district names. Polygon features were converted to point features, with labeling and graduated symbol symbology applied to represent affected Sarvodaya societies by district. Sarvodaya societies represent regional bases of the Sarvodaya Shramadana Movement, a well-organized community-driven organization supporting rural Sri Lankan communities. Final map layouts were enhanced with essential cartographic elements for clarity and effective visualization.
