the sumatra earthquake. haiti was a slip fall where the plates were sliding past. this is a suwduction, the oceanic plate, denser than the south america plate, is subducting beneath the continent. that s similar situation to sumatra in 2004. and those plate boundaries tend to produce the biggest earthquakes because there s the most crust, the area of the crust is largest dipping down beneath the earth. so there s the largest area that can rupture during the earthquakes. that s why you get the large magnitude 8 and 9 earthquakes in subduction zone settings. i don t want to get into the nuts and bolt toos much now because i want to speak to you later in the program and get your visuals. fantastic visuals that will hit home for you viewers. the larger picture of this, haiti just happened. there seem to be a lot of earthquakes. is there anything crazy that s going on? i don t think there s anything crazy.
