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 shaking1185–185 km (115–115 mi)185 km (115 mi)Notes(*) Reports are filtered to exclude those that are likely highly inaccurate or esaggerated.Only reports with latitude/longitude coordinate positions given (1 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! Other users would love to hear about it!If you did NOT feel the quake although you were in the area, please report it as well! Your contribution is valuable to earthquake science and seismic hazard analysis.Compare Quake DataData for the same earthquake as reported by different agenciesThe more agencies report about the same quake and post similar data, the more confidence you can have in the data. It takes normally up to a few hours until earthquake parameters are calculated with near-optimum precision.MagDepthTime GMT2026-08-9EpicenterAgency3.910 km6.2 mi(*)23:51:00Northern Molucca SeaBMKG (Meteorological, Climatological, and Geophysical Agency of Indonesia)3.910 km6.2 mi(*)23:51:00Northern Molucca Sea0 km (0 mi) epicenter difference with BMKGRaspberryShake (RaspberryShake)3.910 km6.2 mi(*)23:51:01MOLUCCA SEA4.7 km (2.9 mi) epicenter difference with BMKGEMSC (European-Mediterranean Seismological Centre)Notes:(*) A depth given as 10 km often means that the the depth of the quake could be not determined with sufficient accuracy.Earthquake statisticsAverage number of earthquakesBased on data from the past 26 years and our earthquake archive back to 1900, there are about 159 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 7 or higher: 0.02 quakes per year (or 1 quake every 62.5 years)Mag. 6 or higher: 0.3 quakes per year (or 1 quake every 3.4 years)Mag. 5 or higher: 5.3 quakes per yearMag. 4 or higher: 50 quakes per year (or 4.2 quakes per month)Mag. 3 or higher: 147 quakes per year (or 12.2 quakes per month)Mag. 2 or higher: 158 quakes per year (or 13.2 quakes per month)The area where this quake occurred has a very high level of seismic activity. It has had at least 2 quakes above magnitude 7 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 60 to 65 years.Number of quakes per yearPrevious quakes in the same area of this earthquake
