Every two years or so, NOAA’s National Centers for Environmental Information updates poster maps based on its Global Historical Tsunami, Significant Earthquake and Significant Volcanic Eruption databases; the 2022 editions are now available. The posters, made in collaboration with the International Tsunami Information Center, are distributed to emergency response personnel; they provide a historical overview of where earthquakes or eruptions took place, or tsunami originated, going back literally millenia. The maps can be downloaded in PDF format: Significant Earthquakes 2150 B.C. to A.D. 2022, Tsunami Sources 1610 B.C. to A.D. 2022, and Significant Volcanic Eruptions 4360 B.C. to A.D. 2022.

Mapping the Sulawesi Earthquake and Tsunami
Last week a magnitude-7.5 earthquake struck the Indonesian island of Sulawesi, triggering a tsunami that struck the city of Palu with far more force than expected. The New York Times has multiple maps and aerial images of the damaged areas; NASA Earth Observatory has before-and-after Landsat imagery.
