Mt. Discovery is a Central volcano. Mt. Erebus is an active volcano on Ross Island. Mt. Harcourt is another strato volcano. Mt. Terror is a very large basaltic Shield. Volcanoes such as these provide interesting opportunities for geological research.
Some volcanoes erupt all the time.
These are called constantly active volcanoes. Stromboli, in Italy, is one such example. Another example is Izalco, in El Salvador. It has been constantly active since 1770. There are many constantly active volcanoes in the Ring of Fire.
