Tectonic plates (or also referred to as lithospheric plates) are the cause of a several natural hazards. Those hazards include earthquakes, volcanic eruptions, and tsunamis. Peru sits on the west side of the South American Plate. It is right next to the Nazca Plate. [Tectonic Plate Map]
The boundary between the two plates is convergent; meaning they move towards each other. The Nazca Plate is an oceanic plate and the South American Plate is continental so instead of colliding, the Nazca Plate sinks underneath the South American Plate (Keller 36). A result of this is the Peru-Chile Trench (Keller 38). According to the book, convergent boundaries cause "great earthquakes; explosive volcanic eruptions; tsunamis, flooding, mass wasting, and subsidence" (Keller 36).

Very clear map and tectonic frame....that compression movement was responsible of course fro the Andes. I found a good link [below] about their formation...It looks like you already know where your country's main quakes will be [some offshore] when you 'll discuss them next week....

Hello fellow classmate! I found your blog post describing Peru's internal structure to be excellent and perspicuous.Like Cuba, I found through your article that Peru faces natural disasters like Earthquakes. I am looking forward to your next blog post.
ReplyDeleteHello Sol, Very good blog post this week. You did a very good job describing plate tectonics, and the map helped the visuals of your post. My country, the Philippines is also at a convergent boundary and shares the same hazards as yours because of the Ring of Fire and similar plate tectonics. Good job, I look forward to visiting your blog again next week!
ReplyDeleteGreat research on the plate properties of Peru! My country (Spain) also found near a convergent boundary, meaning it experiences similar natural hazards such as earthquakes. keep up the good work!
ReplyDeleteHello Sol,
ReplyDeleteMy country is Argentina which is on the same plate as yours so your description very much also applies to my country. I decided to focus on the plate to the East of it which is the African plate and is divergent where the plates are moving away from each other different from the Nazca plate. (Keller 36) Look forward for your next blog post!
