It is commonly measured on the so-called Modified Mercalli Intensity Scale (MMI) ranging from 1 (not felt) to 10 (extreme shaking), and given in Roman numerals as I,II,...IX, X, and often displayed with color codes ranging from light blue to dark red.Earthquake intensity depends mainly on the magnitude and depth of the quake as well as the distance from the epicenter: The further away, the less shaking intensity occurs.Read more about the MMI scale!Number of reports by intensityShaking intensityNumber of reportsMin-Max distance from epicenter (*)Average distance (*)II: Very weak shaking11,157–1,157 km (719–719 mi)1,157 km (719 mi)Notes(*) Reports are filtered to exclude those that are likely highly inaccurate or esaggerated.Only reports with latitude/longitude coordinate positions given (2 in total) could be used for geographic statistics.Get the Android appI didn't feel itI felt this quakeIf you were near the epicenter and felt it, please share your experience and submit a short "I felt it" report!

It has had at least 9 quakes above magnitude 6 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 10 to 15 years.Number of quakes per yearPrevious quakes in the same area of this earthquake
