Madagascar Earthquakes and Volcanoes

Madagascar's volcanoes have not erupted in 80 million years


Madagascar is geologically complex.


Madagascar was originally part of the ancient supercontinent Gondwana, or Gondwanaland and was formed in two major steps. Madagascar west coast was formed when Africa broke off from the supercontinent Gondwana around 165 million years ago. 


The thinned crust on the west coast sagged and the dips filled with sediments, forming deep basins of sedimentary rocks. Then, about 90 million years ago, when the mini-continent migrated, brief but voluminous eruptions covered the island in lava. Madagascar finally broke off from India about 88 million years ago.



Volcanos



A volcano is an opening in the Earth's surface from which gas, hot magma and ash can escape from deep within the Earth.

Earthquakes 


The January 12, 2017 earthquake occurred just after 1 a.m. Madagascar local time, felt in Antananarivo, Antsirabe and the Atsimo-Andrefana region. The earthquake was the eighth largest earthquake in Madagascar's geological history. The strongest earthquake to strike Madagascar happened 68 years ago recording a 6.2.



An earthquake happens when two wedges of the earth suddenly slip past one another shaking the surface of the Earth, resulting from the sudden release of energy in the rigid, rocky outer layer of the Earth creating seismic waves.
