Under this open landscape are found the Undara lava tubes.  Volcanic shapes are seen in the distance and it could be said that those landforms are totally dormant - this land is ancient and mostly flat.

In contrast, Indonesia is no distance away but is a location with active volcanoes where a string of large islands surround a long string of active volcanoes. Mildly active is it.  None the less the population density breaks all records - as I understand.  A long treck in the pre-dawn to view a smoky volcano is a popular endeavour.
Two utterly cataclysmic eruptions are recorded among others.  One eruption was in the much more distant past and has become the scene of a peaceful picturesque and very deep extensive crater lake about 100ks in length. It grabs the imagination.
