Question: is popocatepetl explosive or nonexplosive?
Answer: Like those two volcanoes, Popocatépetl is a stratovolcano, a type of volcano known for its explosive eruptions. It has a long history of eruptions, dating back to the Aztec times. It took a brief 50-year nap from 1944 through the early 1990s, but has since been erupting fairly regularly.
