Mayon in the Philippines is one of Earth's best examples of a classic, conical stratovolcano. Its symmetrical morphology is the exception rather than the rule and is the result of eruptions that are restricted to a single central conduit at the summit. Eruptions are frequent enough to overcome erosion processes that quickly modify the slopes of most volcanoes.
