Studying the Hunga Tonga–Hunga Haʻapai volcano and its evolution in recent weeks is “important for planetary science”, says Petr Brož, a planetary volcanologist at the Institute of Geophysics of the Czech Academy of Sciences in Prague.
Volcanic islands typically last for just months before being eroded away. But Hunga Tonga–Hunga Haʻapai survived for years, allowing Garvin’s team to use satellite observations and seafloor surveys to study how such islands form, erode and persist. The researchers wanted to use that knowledge to understand how small conical volcanoes found on Mars may have formed in the presence of water billions of years ago.
Many volcanoes on Mars are thought to have erupted with steady flows of lava, but some could have been explosive, like Hunga Tonga–Hunga Haʻapai, says Joseph Michalski, a planetary scientist at the University of Hong Kong. Teams around the world are now monitoring the island using optical, radar and laser satellites to measure what is left. The International Space Station’s Global Ecosystem Dynamics Investigation instrument has also collected data, says Garvin.
