People likely experienced very weak shaking there. Several smaller towns and villages are located closer to the epicenter and might have experienced stronger shaking.The following table shows some of the places that might have been affected (or not) by the shaking.DistancePlaceMax. shaking intensity(*)RegionCountry60 km (37 mi)SE of epicenterMasohi(pop: 36,400)II: Very weakKabupaten Maluku Tengah, MalukuIndonesia63 km (39 mi)S of epicenterAmahai(pop: 47,700)II: Very weakKabupaten Maluku Tengah, MalukuIndonesia118 km (74 mi)SW of epicenterAmbon(pop: 347,300)II: Very weakMalukuIndonesia281 km (174 mi)NW of epicenterLabuha(pop: 7,070)I: Not feltKabupaten Halmahera Selatan, North MalukuIndonesia351 km (218 mi)NE of epicenterSorong(pop: 254,300)I: Not feltSouthwest PapuaIndonesiaNotes:(*) Shaking intensity according to the Modified Mercalli Intensity Scale (MMI) and estimated using seismic models.User-reports for this quakeThere are no user reports for this quake yet.If you felt it, be the first to report it!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 has had at least 3 quakes above magnitude 6 since 2000, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 5 to 10 years.Number of quakes per yearPrevious quakes in the same area of this earthquake
