Earthquakes
Frequent in Peru
The Andes Mountains were created by seismic action and that action continues.
At any hotel, ask employees to point out which places are the safest. Signs that show where to go in case of earthquake are required by law for all public and commercial buildings. Look for a green S and the words “zona segura en casos de sismos,” which means “safe zone in case of earthquake.”
Even outdoor places that are particularly seismically active will show where to go in case of earthquake. The Pisac archeological site has red flags on dangerous areas and green flags at safer spots.
Inca constructions were designed to withstand earthquakes. They used smaller stones between larger ones so that the smaller ones would break, protecting the larger ones. They also carved the stones so that they fit together like Legos.
Register your presence in Peru with your embassy. Peruvians get disaster alerts on their phones and your embassy might do the same. For US citizens, enroll in the STEP program.
