Callao, Peru earthquake struck near Lima

Peru Earthquake Rattles Capital

Peru’s earthquake shook some buildings in the capital of Lima on Tuesday afternoon shortly before 2 PM local time. The epicenter of the quake was roughly 22 miles away, as you can see from the map below provided by the US Geological Survey (USGS).

The tremblor spread out from a depth of a tad less than 38 miles. At the time of writing, there were no reported injuries or major damage from the quake.

There was a bit of excitement when it first struck.

According to the Christian Science Monitor, early reports yesterday suggested that the new Peru earthquake could be as powerful as 5.6. But the USGS has now confirmed that the earthquake was a 4.6 on the Richter scale.

Because the Richter scale is logarithmic, that means that there’s a substantial difference between the two figures. How Stuff Works explained it this way:

“[T]he wave amplitude in a level 6 earthquake is 10 times greater than in a level 5 earthquake, and the amplitude increases 100 times between a level 7 earthquake and a level 9 earthquake. The amount of energy released increases 31.7 times between whole number values.”
