Since 1998 the Alaska Earthquake Center has partnered with the Alaska Division of Geological and Geophysical Surveys and the Alaska Division of Homeland Security and Emergency Management to produce maps that display tsunami hazards for coastal communities. These tsunami inundation maps show areas that would be flooded during a worst-case tsunami event.

The tsunami maps are now available through a mobile-friendly web tool. The tool allows you to quickly access communities with inundation products and explore various types of data in an online map interface. You can zoom in and out of areas of interest, turn data layers on and off, and even quickly share your map and settings with others, not to mention the ability to bookmark your map for future use.

You can access the map by visiting or clicking on Tsunamis > Tsunami Inundation Maps above.

The following instructional video walks you through the tool’s use and its new features.
