When it comes to volcanoes in Peru, there are multiple along and close by the coast. Peru's volcanoes belong to the subduction zone of the eastern Pacific Nazca plate beneath the South American plate (Volcano Discovery).
The image below is the stratovolcano Ubinas, which is Peru's most active volcano. Ubinas is composed of Pleistocene, and has a 1.2-km-wide caldera that cuts across the top of the volcano. .
Many of the volcanoes in Peru are active. Since they are active, Peru has information on high level hazards to be safe due to activity from volcanos. According to Think Hazard, they recommend the people of Peru take action on early warning signs of an eruption. By clicking this link, http://www.thinkhazard.org/report/195-peru/VA, there will be a list of precautions taken by the country to stay protected during any event that is damaging.

Seismicity of Peru
In this weeks chapter we learned about earthquakes. Since Peru is located near a subduction zone, it's more likely to experience many earthquakes. They are more common for the fact that the Nazaca and South American plate are by the Peruvian Coast.
We also learned about seismicity, which is a happening of earthquakes in a region. The seismictiy in Peru goes from increasing from inland to the Peruvian coast. This week has been somewhat active. Two days ago there was an earthquake near Coracora and Ayacucho, Peru that was 5.1 in magnitude. Also, today there was one near Paracas and Ica that was 4.2 magnitude (Earthquake Track).
Even though it is hard to predict earthquakes, Peru now has two ways of dealing them using the American Red Cross and Peruvian National Institute of Seismology that say "drop, cover, and hold on", or the American Rescue Team International that uses "The Triangle of Life Method" (LimaEasy). It is also recommended to stay calm and to stay in a safe place if you are indoors.

Peru and Plate Tectonics
In week two, we learned about the Earth's tectonic plates. The words tectonic refers to large-scale geological processes that deform Earth's lithosphere (Keller). With the plates being broken down all over earth taking part of a continent and section of water, I located Peru to see what plate it was placed on.
Being part of the ring of fire, Peru is located on top of the South America plate boundary and south of that is the plate Nazca. Because the Nazca plate moves east towards the South American plate, that makes it convergent boundary. According to Keller, a convergent boundary is when two plates are moving towards one another.
Since Peru is near the Nazca plate and on the South America plate, it is prone to most earthquakes that occur around the world. Due to subduction, we see more shallow earthquakes closer to the subduction zone and deeper ones inland (IRIS).
Peru also is more likely to experience tsunami's because of the activity of the Peru-Chile trench. In 2001, Peru had an earthquake of 8.3 which created a tsunami off the Peruvian coast where damage occurred. (USC Tsunami Research Group).
