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.

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.
