In early 2015, a volcanic eruption in the Kingdom of Tonga created a new island informally known as Hunga Tonga Hunga Ha'apai (HTHH). The subsequent evolution of the new island was previously described in "The Birth of a New Island" available here. Below are additional visualizations, including an updated view of the island's appearance in March 2018 as well as some visualizations of the martian surface. 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.

The complete visualization of "Using Earth to understand how water may have affected volcanoes on Mars" is available here.

This visualization shows the two original islands in Tonga, Hunga Tonga and Hunga Ha'apai, as they appeared in December of 2014. The visualization fades to the new island informally known as Hunga Tonga Hunga Ha'apai as it appeared in March 2018, after the severe tropical cyclone Gita passed over the region.
This video is also available on our YouTube channel.

This visualization is similar to the one above except that artificial water has been added to show how water may have eroded landforms on Mars during epochs when persistent surface water was present.

Coming soon to our YouTube channel.
