Atlas of Volcanic Topography (AVT)
Overview
Atlas of Volcanic Topography (AVT) is a compilation of 2D and 3D topographical maps of volcanoes and tectonic landforms created by F. Ikegami. Most of the images are TopoUSM shading applied, which enables more realistic representation of the topography.
Explore
- United States
- Japan & Izu-Bonin arc
- Europe and Africa
- SE Asia and Oceania
- Central & South America
- Kamchatka
There are 99 maps for 30 volcanoes in total. These categories are subject to change as more maps are coming in the future.

Deep submarine rhyolitic lavas at Havre, Kermadec arc
Rhyolitic lava lobes, domes, and giant pumices erupted at the 1000~1500 meters depth at Havre volcano in Kermadec arc around 2012. The red color shows the degree of topographic changes between 2002 and 2012. I was fortunate to participate to a research voyage in 2015 and created this map for the project investigating the eruption.

Andesitic lava morphology at Nishinoshima, Izu-Bonin arc
New andesitic lavas were extruded at Nishinoshima in 2017 (Shown in silver) after its island-forming eruption in 2013-2015 (Dark colored area). This image illustrates how it is difficult to distinguish the two eruptions with the lava morphology.

Volcanoes in Bali Island, Indonesia
This figure was intended to clarify the geographical locations of Mt. Agung in Bali Island during the volcanic crisis in 2017. Agung is the stratovolcano at the front which is 50 km away from Denpasar at the left end.
