You are dropped off by helicopter at a site on the land. You are told that it is a plate boundary. Almost immediately, you feel an earthquake. You look around and note the absence of volcanoes, but you notice an offset stream channel, and find a vertical fault with two kinds of rock on either side of it. What sort of plate boundary are you most likely on?

The presence of an earthquake, an offset stream channel, and a vertical fault with different types of rock on either side, but no volcanoes, suggests a transform plate boundary. This is where two plates slide past each other, causing earthquakes but not typically creating volcanoes.
