pacific plate
section::::tectonic plate boundaries.:transform plate boundary.









































a transform-fault boundary, or simply a transform boundary is where two plates will slide past each other, and the irregular pattern of their edges may catch on each other. the lithosphere is neither added to from the asthenosphere nor is it destroyed as in convergent plate action. for example, along the san andreas fault strike-slip fault zone, the pacific tectonic plate has been moving along at about 5 cm/yr in a northwesterly direction, whereas the north american plate is moving south-easterly.

produced by the subduction of the juan de fuca tectonic plate, which moves slowly in a northeastward direction with the gorda tectonic plate under the north american tectonic plate, mazama is part of the cascade volcanic arc that stretches from northern california to southern washington state. mazama sits among a region of crustal extension marked by fault zones, including north–south-trending normal faults such as the annie spring fault within the west klamath lake fault zone, which might produce damaging earthquakes. likewise, the red cone spring fault cuts through basaltic andesite deposits at red cone from 35,000 years ago; together, the two faults move at an average rate of each year. there do not appear to be faults present in the crater lake caldera wall, but the volcano induced a stress field in the upper crust nearby.
