title: HazMiner dataset

description: The HazMiner dataset contains the location, timing and impact of geo-hydrological hazard events (flood, landslide and flash flood) at the global scale. The data is extracted using a paragraph based text mining method called HazMiner. It uses large language models to extract infromation from online news articles. The HazMiner method is specifically designed to improve the documentation of geo-hydrological hazards in the Global South. 

The current version contains events from 2017 through 2024, containing 21,411 flood, 7,659 landslide and 3,606 flash flood events, extracted from 6,366,905 news articles in 58 languages.

More information on the code

General information

The dataset contains information on the articles, paragraphs and events. 



Articles (Level 1): the articles used to extract the geo-hydrological events

Paragraphs (Level 2): the paragraphs of the corresponding articles with their extracted information on the location, timing and impact 

Events (Level 3): geo-hydrological hazard events represents clustered paragraphs that occur around the same time in space


The datasets are linked to eachother by different ids, each article, paragraph and event has its own id assigned. All articles were extracted from the GDELT Global Knownledge Graph (GDELT, 2025).
