The earthquakes in this area do not reach high depths. This is due to the fact that the plate is dipping shallowly. The deepest earthquake is around 160 km deep.]]> 2022-03-16 20:52:04 UTC https://padlet.com/liamcrigs/up17gr6tr184u8t4/wish/2098803121 DIP AND CROSS SECTION caedenmcgregor713 https://padlet.com/liamcrigs/up17gr6tr184u8t4/wish/2098803587 In the southern most point go the Mexican subduction zone the Plate is dipping at an angle of 43º into the sub surface.
In the middle of the plate boundary the plate is dipping at an angle of 20º, and at the most northern point it is only dipping at an angle of 7º.]]> 2022-03-16 20:52:30 UTC https://padlet.com/liamcrigs/up17gr6tr184u8t4/wish/2098803587 Google Earth Pro Data of the Coast of Mexico https://padlet.com/liamcrigs/up17gr6tr184u8t4/wish/2098807799 2022-03-16 20:56:44 UTC https://padlet.com/liamcrigs/up17gr6tr184u8t4/wish/2098807799 https://padlet.com/liamcrigs/up17gr6tr184u8t4/wish/2098817812 2022-03-16 21:06:48 UTC https://padlet.com/liamcrigs/up17gr6tr184u8t4/wish/2098817812 STRUCTURE OF SUBDUCTION ZONE https://padlet.com/liamcrigs/up17gr6tr184u8t4/wish/2098852733 Trends along south coast of Mexico with strike SE - NW. Dips to the east with dip varying from shallow in the north to moderate in the south.
The subduction zone is composed of the downgoing Cocos plate, with the North American plate overriding in the north and Caribbean to the south.]]> 2022-03-16 21:38:26 UTC https://padlet.com/liamcrigs/up17gr6tr184u8t4/wish/2098852733 Why the subduction zone changes shape? https://padlet.com/liamcrigs/up17gr6tr184u8t4/wish/2098864385 Subduction occurs below the North American plate to the north with shallow dips recorded here (07). In contrast, dips in the south are much larger (20 - 40) with subduction occurring below the Caribbean plate. Composition of the Caribbean plate is oceanic compared to the continental North American plate. 
The shape of the subduction zone may also be affected by the geotherm varying in places (warm vs cool mantle) which will affect at what depth metamorphism to eclogitie occurs and the amount of slab pull.]]> 2022-03-16 21:52:30 UTC https://padlet.com/liamcrigs/up17gr6tr184u8t4/wish/2098864385 Cross Section through subduction zone https://padlet.com/liamcrigs/up17gr6tr184u8t4/wish/2098882885 2022-03-16 22:16:25 UTC https://padlet.com/liamcrigs/up17gr6tr184u8t4/wish/2098882885
