Java is covered with 110 volcanoes in a mountain chain stretching from east to west, 35 of them are still active and occasionally erupts. Even if an eruption can cause a lot of damage and suffering, it is also the reason why Java is one of the most fertile agriculturural regions in the world. Compared to other geographic regions the volcanic ash here is non-acid, on the contrary it nurtures the soil and the plant life.

If you are planning a trip, wherever you are going, a good map is an essential tool to help you decide where to go and how to get there.
