Using Earth to Understand How Water May Have Affected Volcanoes on Mars

This scientific data visualization shows the evolution of the newly-erupted island in the Kingdom of Tonga. Results of this study can enhance our understanding of numerous small volcanic landforms on Mars whose formation may have been in shallow-water environments during epochs when persistent surface water was present.

- Volumetric erosion for new hydromagmatic island is approximately 0.0026km3/year
- Demostrated first meter-scale documentation of landscapes and topography for a new volcanic island over its initial stages of evolution (approximately 3 years)
- Satellite-based measurements of news island predict lifetime of up to approximately 42 years
