Semeru is Indonesia's most frequently erupting volcano, with Vulcanian (ash) explosions happening every 20 minutes on average since 1967. During periods of high activity, pyroclastic flows often descend the south flank. Climbing Semeru is an arduous 3-day affair and allows no views into the crater due to the extreme danger of approaching the crater rim (several people have been killed by explosions here, including volcanologists). The crater is open to the south, so the Sawur Volcanological Observatory, located near the base of the mountain on that side, is a great place to watch (and hear) the eruptions - the only problem is that it is very hard to find. A much more distant but even more impressive viewpoint is the summit of Mt. Penanjakan, which offers what is deservedly one of the most famous volcanic views in the world - the panorama across the vast Tengger Caldera and active Bromo volcano (which erupts every few years) to the perpetually smoking Semeru.
