Peru is a seismically unstable country—both Lima and Cusco have been leveled by earthquakes—and Machu Picchu itself was constructed atop two fault lines.
Does Machu Picchu get earthquakes?
The Incan citadel of Machu Picchu in Peru is known for its marvelous stonework. But several structures at the site suffered through at least two earthquakes as they were being built, a new study suggests. Those temblors not only damaged walls, but also triggered a sudden change in construction techniques.

Is Machu Picchu at risk?
Machu Picchu faces a variety of threats: excessive tourism, which is especially hard on the fragile site; the generation of solid waste; unsustainable agriculture practices; overgrazing and forest fires; aggravating erosion; landslides; mineral extraction; and the introduction of exotic plants.
What problems is Machu Picchu facing?
Up to 2,000 people visit the Machu Picchu citadel every day, with visitor numbers growing at 6 percent a year. The site is being slowly eroded by tourists’ feet. Machu Picchu is located among steep slopes that are constantly being eroded by heavy rains and landslides are common.
Why does Machu Picchu survive earthquakes?
But Inca construction has a remarkable number of design features that protect buildings against collapsing in an earthquake. These include: Terraces buttress steep mountain slopes. Precisely fitting and mortar-free stone walls move (dance) during an earthquake, resettling as they were before the event.
When should you avoid Machu Picchu?

Where do most earthquakes occur in Peru?
Although the whole of Peru is subject to minor earthquakes and earth tremors, the present epicentre appears to be farther north than the most seismic district in Peru, namely, the regions around Arequipa.
What fault line is Peru on?
The Cordillera Blanca Fault Zone (Spanish: Falla Cordillera Blanca) is a system of geological faults located next to Cordillera Blanca in the northern Peruvian Andes. The fault is considered the most active one in northern Peru. The last time the fault ruptured was in the 1500s or before.
Why was Machu Picchu built on fault lines?
The fault lines running through the site probably directed melting snow and rainwater to the high-altitude outpost providing water. And the network of fissures below the site likely allowed it to drain, one of the reasons the city has lasted so long.

Is Peru on a fault line?
In the south, Peru is dominated by thrust faulting along the forearc and sub-Andean zones, largely in response to subduction, whereas left-lateral strike-slip and normal faulting are characteristic of higher elevations and the retroarc region to the east (Dalmayrac and Molnar, 1981; Dewey and Lamb, 1992; McNulty et al.
