Approx. 2,210 people were in areas with light shaking (intensity IV), the highest intensity this quake likely produced over inhabited areas.MMI LevelShaking (5,305 in total)Possible damageI Not feltNoneII Very weak31(0.58%)NoneIII Weak3,057(57.62%)Probably noneIV Light2,217(41.79%)None or minor onlyV ModerateMinorVI StrongMinor to ModerateVII Very strongModerateVIII SevereSignificantIX ViolentHeavyX ExtremeCatastrophicEstimated number of people exposed to shaking from the earthquake by intensity (data coverage corresponding to attached map)Map of expected ground shaking intensity according to the MMI scale (shakemap, source: USGS)Map with population density (from white to black) in the area around the quake's epicenter (source: USGS)Alert level for this earthquake: Level GREENBased on seismic and statistical models, USGS estimates that the risk of fatalities and damage from this earthquake is low. The main factors that contribute to this evaluation are:The maximum expected ground shaking from this quake was unlikely to reach dangerous levels over populated areas; it should not have surpassed intensity IV (Light) on the MMI scale significantly.The quake appears to have occurred far from densely populated areas (far as in relation to its magnitude).The quake occurred relatively deep under the surface (79 km or 49 mi depth). This significantly weakened the shaking on the ground of this quake if compared to a magnitude 5.4 event at shallower depth.CommentOverall, the population in this region resides in structures that are resistant to earthquake shaking, though vulnerable structures exist. The predominant vulnerable building types are adobe block and unreinforced brick with mud construction.A magnitude 7.5 earthquake 133 km nw of this event struck this region on June 8, 1993 (UTC), with estimated population exposures of 2,000 at intensity VI and 4,000 at intensity VII, with no reported fatalities.Source: USGSGreen alert for shaking-related fatalities and economic losses. There is a low likelihood of casualties and damage.Expected fatalitiesThe risk of fatalities from this quake is considered low and classified as Level GREEN, the lowest on a color scale from Green (low) to Red (very high). USGS estimates that there is a 90.4% chance that there are no direct fatalities as effect of shaking and a 9.1% chance that between 1 and 10 fatalities occurred. The likelihood that there are more than 10 fatalities is less than 1%.Expected economic damageThe economic impact of this earthquake is expected to be minimal or small (Level GREEN). Only light damage if any should have occurred. USGS calculates an 90.4% chance of total economic loss in the range of 0-1 million US Dollars and a 9.1% risk of losses between 1 and 10 million US Dollars. Total economic loss from this quake is not likely to surpass 1 million US Dollars (less than 1% chance).

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 (*)IV: Light shaking138–38 km (24–24 mi)38 km (24 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!
