PTHA Based Tsunami Inundation Tool QGIS 4 compatibility
Not QGIS 4 ready Active
Not yet — the latest version declares max QGIS version 3.99.0, so it is not offered to QGIS 4 users.
A QGIS processing plugin that generates tsunami inundation hazard zones using Probabilistic Tsunami Hazard Assessment (PTHA) water levels and coastal digital elevation models.
About
PTHA Based Tsunami Inundation Tool provides an automated workflow for mapping tsunami inundation zones using Probabilistic Tsunami Hazard Assessment (PTHA) derived water levels and high-resolution coastal elevation data. The tool integrates spatial analysis techniques including nearest-point association, water level computation at different exceedance rate, raster-based inundation detection, and polygon generation of hazard zones. It is intended to support tsunami hazard assessment, coastal risk analysis, and emergency planning.
