The Indonesian island of Java is almost entirely of volcanic origin, and contains numerous volcanoes, 45 of which are considered active volcanoes. As is the case for many other Indonesian islands, volcanoes have played a vital role in the geological and human history of Java. Indeed, land is created on Java as a result of lava flows, ash deposits, and mud flows (lahars). Volcanoes are a major contributor to the immense fertility of Java, as natural erosion transports volcanic material as alluvium to the island's plains, forming thick layers of fertile sediment. The benefit is not just in the immediate vicinity of the volcano, with fine ash emitted from eruptions being dispersed over wide areas.
The Raung (ꦫꦲꦸꦁ), or Mount Raung is one of the most active volcanoes on the island of Java in Indonesia. It is located in the province of East Java and has a 2-kilometer-wide (1.2 mi) and 500-meter-deep (1,600 ft) caldera surrounded by a grayish rim. The difference in color of the rim and the flanks of the volcanoes is caused by the rim’s lack of vegetation compared with the healthy and extensive vegetation on the flanks. Raung, standing almost 3,332 metres (10,932 ft) above sea level, is the tallest volcano of this cluster.Its summit, in Bondowoso Regency, is also the highest point of the regency.
