So far, we have received 4 reports for this quake from India. Out of these, 3 people indicated they felt it. The quake was reported to have been felt in up to approx. 50–70 km (31–43 mi) distance, with isolated cases to have felt the quake even 73 km (45 mi) away.Most reports came from Dharapur (1 report), a town with 8,100 inhabitants in Assam in 77 km (48 mi) distance west of the epicenter, India, Chota Haibor (1 report), a town with 6,300 inhabitants in 34 km (21 mi) distance east of the epicenter, and Morongial (1 report) (33 km or 20 mi to the east). Further below is a list of places where most people reported this quake.This section is being updated as new data comes in.User reports estimate the perceived ground shaking intensity according to the MMI (Modified Mercalli Intensity) scale.Contribute:Leave a comment if you find a particular report interesting or want to add to it.Flag as inappropriate.Mark as helpful or interesting.Send your own user report!TranslateNagaon (267.6 km ENE of epicenter) [Map] / not felt / rattling, vibrating / 2-5 sNagaon (32.7 km E of epicenter) [Map] / Weak shaking (MMI III) / 2-5 sChota Haibor, Nagaon district, Assam (34.4 km ESE of epicenter) [Map] / Weak shaking (MMI III) / very short : Felt my chair moving Guwahati (72.9 km WSW of epicenter) [Map] / Weak shaking (MMI III) : Shaking List of cities/places with most reportsPlaceDistance from epicenterAverage reported Shaking IntensityNr. of reportsDharapur, Assam, India(Pop.: 8,095)77 km (48 mi)W of epicenterIII: Weak shaking1Chota Haibor, Assam, India(Pop.: 6,315)34 km (21 mi)E of epicenterIII: Weak shaking1Morongial, Assam, India(Pop.: 10,318)33 km (20 mi)E of epicenterIII: Weak shaking1Note: Only reports with latitude/longitude coordinate positions given (4 in total) could be used for statistics.What is Intensity and the Mercalli Intensity Scale?The amount of shaking that occurs on the surface due to an earthquake is called the intensity. 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 (*)I: Not felt1267–267 km (166–166 mi)267 km (166 mi)III: Weak shaking333–73 km (20–45 mi)47 km (29 mi)Notes(*) Reports are filtered to exclude those that are likely highly inaccurate or esaggerated.Only reports with latitude/longitude coordinate positions given (4 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!
