We have read some reports in the media about the total seismic events recorded in Peru for the year 2013. Most of these statistics only include data with earthquakes that were felt by the population. The Peruvian Institute of Geophysics (IGP - Instituto Geofisico del Peru) published a report with a total 217 seismic activities for last year.

Peru is situated along the boundary of two tectonic plates: the Nazca Plate and the South American Plate. The interface between these two plates is located near the Peruvian coast. At a rate of about 50 mm (2 inches) per year the South American Plate is moving towards the Pacific Ocean over the Nazca Plate. That may not sound a lot but it is enough to put huge strain on the Earth's crust. The pressures are periodically released through earthquakes.

The subduction of the Nazca Plate caused millions of years ago the rise of the Andes Mountains, the creation of the Peru-Chile Trench and the volcanism in the Peruvian highlands. Until today this process continues and causes a number of geo-dynamic processes. The consequent results of a heavy earthquake striking the area are destruction, panic, fear, innocent casualties, poverty, hunger and diseases.

Total Earthquakes in Peru for 2013

We also keep track of all earthquakes in the country over 3.5 on the Richter scale by analyzing the raw data issued by the "IGP" and "USGS" (U.S. Geological Survey). As our data does also include seismic activities in unpopulated areas, there is quite a difference in these numbers:

Total of Earthquakes: 456
Northern Peru: 110
Central Peru: 151
Southern Peru: 195

Earthquake Magnitudes:

Between 3.5 and 3.9 on the Richter scale: 74
Between 4.0 and 4.9 on the Richter scale: 360
Between 5.0 and 5.9 on the Richter scale: 20
Between 6.0 and 6.9 on the Richter scale: 2

Earthquake Depths:

From 5 to 49 Km (3.1 to 30.4 miles): 237
From 50 to 99 Km (31 to 61.5 miles): 109
From 100 to 199 Km (62 to 123.5 miles): 106
From 200 to 299 Km (124 to 186 miles): 4
