Costa Rica lies on the Caribbean Plate which predominates the Cocos plate. Because these two plates shift often Costa Rica experiences a lot of seismic activity including some tsunamis. These plates are also the cause for volcanoes.T he Central America Volcanic Arc is formed here. This arc extends from Costa Rica to Guatemala.
The Caribbean Plate is bordered by two major plates, and two minor plates.
Hi, Nick! I looked carefully at the Earth Tectonic Plates Map and it looks like Costa Rica is located at a convergent plate boundary between the two plates that you identified, the Caribbean Plate and the Cocos Plate. Clearly, convergent plate boundaries where plates are colliding and resulting in subduction zones and deep-sea trenches on the ocean floor or in the case of a continental collision boundary, resulting in the formation of mountains are arguably most "varied" in the type of hazards they produce: from earth quakes to flooding and landslides. I did not suspect Costa Rica had a significant seismic activity but after looking it up on the Earth's Tectonic Plates map, I realized the potential it had for such geological events. You definitely chose one country that you have so much to talk about in terms of geological phenomena! Look forward to your following post!
