Replication data for: SEATANI: Hazards from seamounts in SouthEast Asia, Taiwan, and Andaman and Nicobar Islands (eastern India)

In this work, we compiled a dataset of volcanic seamounts for southeast Asian and some neighbouring countries (SEATANI dataset). We then characterised these seamounts in terms of morphology and evolution stage, and used this information for understanding their hazard potential. Lastly, we calculated the exposure potential of key assets (population, submarine communication cables, and ship traffic density) from these seamounts and identified key seamounts and areas that should be investigated in future focused studies.
