Sabrina's Blog 5: Madagascar Volcanoes

Image
  Madagascar: Volcanoes Volcanoes happen constantly when there is a divergent plate boundary. Divergent plate boundaries are plates that pull away from each other. Most divergent plates are discovered along mid-ocean oceanic ridges. These plate boundaries cause the hot mantle rock to emerge since the plates are moving apart. Divergent plate boundaries cause volcanic activity and small earthquakes. Madagascar has a divergent plate, so volcanic activity can occur on the island. Madagascar has a medium level of volcanic activity. The activity is mostly centered in the middle of the island. If a volcano were to occur sooner than expected, people should move south of the island. The volcano is a bit north of the island. The volcanic lava can cause damage to multiple buildings leading to casualties. Also, ashes from the lava and maybe fire can cause a public health hazard. The ash can cause sensitivity to the eyes and airways. Madagascar can do some numerous preparations for volcanic act...

Sabrina's Blog 3: Madagascar Earthquakes

  Madagascar Earthquakes Madagascar is exposed to many hazards such as cyclones, floods, and sometimes earthquakes. Madagascar has an early warning system for natural hazards. An early warning system is an instrument used as a monitoring system, forecasting, and predicting disasters that may occur and can be at risk to human life. This assists with the prevention of losing human life. There is also a 9-3-0 Hotline located specifically in Madagascar. Madagascar has a low level of earthquakes. It isn’t too constant or too hazardous compared to the other events that happen. On the other hand, Madagascar has a high hazard level of landslides as well as cyclones. The constant rainfall, earthquakes, and other possible hazards make the landslides a periodic hazard. Madagascar is only about a thousand miles long and two-hundred fifty miles wide. This island is bigger than California. The recurrence of cyclones makes the entire continent an extremely high level of being hazardous.   Re...

Sabrina's Blog 2: Madagascar Plate Tectonics

Image
  Madagascar Plate Tectonics Madagascar is within the African Plate since the country is very close to Africa. The country is next to the Australian Plate. Madagascar is outside of the Ring of Fire. Within the country, there are active volcanoes from the last million years. Madagascar is close to the Southwest Indian Ocean. There is also a common earthquake activity. Madagascar has a convergent plate, and the map declares there is an overriding plate.  The African plate consists of both an oceanic plate and continental crust. The country is within the Atlantic Ocean and close to the continent of Africa. The plate boundary has both convergent and divergent boundaries. A convergent boundary that refers to two continent tectonic plates colliding. The oceanic crust with subduct underneath the lighter continental crust. If one side becomes stuck in any way, there will be more than enough pressure to cause an earthquake. If the material goes further, the heat would cause it to melt ...
