Visualizations of Hunga Tonga Hunga Ha'apai and the Martian Landscape

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.
