Peru is one of the hosts for the Andes Mountain Range. The Andes are a Mesozoic-Tertiary orogenic belt formed along the Pacific Ring of Fire, formed during the Cretaceous period about 138 million years ago to 65 million years ago. The Andes were caused by the subduction of the oceans crust beneath the Southern American plate.
The Pacific Ring of Fire is an area where a number of earthquakes and volcanic activity goes on. The Ubinas volcano is one of the most active volcanoes located in this area (Peru). The most recent eruption was in 2010 and continues to create disruptions. Ubinas is a strato-volcano also known as a composite volcano with a summit elevation of 18,609 ft. Ubines has a 1.4-km-wide caldera cut.
A strato or composite volcano is a tall conical volcano, made up of my strata layers of harden lava and other rock fragments. A caldera is a large chunk that collapses back in the volcano when an eruption occurs.
Ubinas active eruptions have left the area bare of no trees, no plants and no wild life. In some cases the hazardous chemicals released by the volcano has caused savior illnesses upon nearby residents.

ReplyDeleteI'm so happy someone decided to blog on Peru since I am actually going there over spring break. I actually had no idea that Peru had active volcano's let alone a COMPOSITE volcano which erupted last year! I think it is really interesting how because of the recent eruptions there are no trees or wildlife. Reading this blog makes me really excited to visit this exotic country.
Jesus,
ReplyDeleteI like the overall content of your blog, I would talk more the relations between the formation of the mountain ranges and the volcanic activity. Also when describing the Ubinas volcano may want to go more in depth on the forms present. All in all it's a good intro to geographic data about Peru.
