Earthquakes around the world

Today during class, we were suppose to investigate the earthquakes that were happening around the world. The blue colored line shows where the compression of earthquakes occurred. Compression is when the movement of the tectonic plates causes the rock to squeeze until it folds. As seen in the picture, the compression of earthquakes happened around the Arabian, Eurasian and Philippine plates. The green colored lines shows the tension of the earthquake. Tension is a force that stretches the rock so it becomes thinner somewhere in the middle. The earthquakes that cause tension usually happen around the Indo-Australian and African plates, and a little around the Pacific Ocean (Nazca plate.) The last type of stress that occurred the earthquake is shearing. Which the pink represents. Shearing is when the rocks push in two directions. This can cause the rock to slip apart or change its shape. The earthquakes that cause shearing usually cause a lot of damage and those damages can be really dangerous. The earthquakes shearing happens on the Western part of the U.S and a part of the South American. Shearing also occurred in the Indian Ocean which is really near Australia. The most type of earthquake that occurs I think is tention, this is because, since tension mostly appears in the Indian Ocean, and in the Atlantic Ocean, it affects the lands that are either of the sides of these oceans. I have looked at the data that our teacher Mrs. M gave us, and some of the most devastating earthquakes have happened around South America and the outline of India.
