The Tengger Caldera

The Tengger Caldera

This is the most popular view of the Tengger Caldera in East Java. A caldera is a collapse crater from a massive volcanic eruption which accurs after the underlying magma chamber has cooled and collapsed leaving a huge crater, in this case about 30 Km across. You can see the crater rim crearly outlined on the left. The small smoking cone in the middle distance is Mt Bromo, an active volcano. The large smoking mountain in the distance is Mt Semeru, a 3,700m monster that erupts every 10-20 minutes. It is a tough climb, but woth the effort as you then get to see an active volcano from very close range. It’s not as dangerous as it sounds because the frequent eruptions do relieve the pressure, and large eruptions tend to occur after a period of low activity (but nothing about a volcano is entirely predictable). This is well worth a vist if you ever get the chance.
