Plate Boundaries

The United States has several tectonic plate boundaries going though the states which is why we experience earthquakes and some volcanic activity. The united states fall more under the north American plate which has two plate boundaries, transform boundary and convergent boundary. Both plates are the most active plate boundaries that are on the west coast of the United States. The East coast also has a plate but it's not as active as the west coast. 
The United States has a "ring of fire" which is closer to home. The San Andreas Fault is the sole responsibile for the earthquakes we have here in California. They slowly move past each other.  Hawaii doesn't have a plate boundary but they do have a "hotspot" in the middle of the pacific plate which makes the magma to rise from the earth creating volcanos and islands.

Natural hazards have two different catorgeries. Natural processes and natural hazards. Natural processes becomes hazardous when the humans are in the surrounding areas as in like earthquakes where people live and or volcanoes in Hawaii. A natural hazard starts off as a natural processes but then can turn into a natural hazard when there is a slight chance that there is threat to humans.  A disaste...
