Number of known significant earthquakes, 2017

Estimated annual number of significant earthquakes. A significant earthquake is classified as one that meets at least one of the following: caused deaths, moderate
damage ($1 million or more), magnitude 7.5 or greater, Modified Mercalli Intensity (MMI) X or greater, or generated a tsunami. Due to reporting and evidence, recent
data will be more complete than the long historical record; an increase in reported earthquakes over this period therefore doesn't indicate a true increase.
