A leading global science and technology institution of empowered men and women helping develop communities safe from and resilient to volcanic eruptions, earthquakes, tsunamis and other related hazards



We provide timely, quality and socially-inclusive information and services for warning, disaster preparedness and mitigation. This we do through the development and application of technologies for the monitoring and accurate prediction of, and determination of areas prone to, volcanic eruptions, earthquakes, tsunamis and other related hazards, and gender-responsive capacity enhancement for comprehensive disaster risk reduction.



  • Predict the occurrence of volcanic eruptions and earthquakes and their related geotectonic phenomena
  • Determine how eruptions and earthquakes shall occur and also areas likely to be affected
  • Generate sufficient data for forecasting volcanic eruptions and earthquakes
  • Mitigate hazards of volcanic activities through appropriate detection, forecast and warning system
  • Formulate appropriate disaster preparedness plans
