Volcanoes do not typically occur at transform boundaries. One of the reasons for this is that there is little or no magma available at the plate boundary. The most common magmas at constructive
What boundary causes volcanoes?
The two types of plate boundaries that are most likely to produce volcanic activity are divergent plate boundaries and convergent plate boundaries. At a divergent boundary, tectonic plates move apart from one another.
What do transform boundaries cause?
The grinding action between the plates at a transform plate boundary results in shallow earthquakes, large lateral displacement of rock, and a broad zone of crustal deformation. Perhaps nowhere on Earth is such a landscape more dramatically displayed than along the San Andreas Fault in western California.
