Merapi volcano is one of the world’s most active and dangerous volcanoes. It contains an active lava dome, which regularly produces pyroclastic flows. It has been active for 10,000 years. This fire mountain remains one of the most active and dangerous volcanoes in the world.
It can be seen from its name; Merapi from Javanese word ‘Meru’ means ‘Mountain’ and ‘Api’ means ‘fire’. The internally giant smoking Mount Merapi is one of the active volcanoes that found in Indonesia. It is presenting its peaceful and sleepy dense forest.
Beyond this, there lies a vast deserted land with its deep and steep valley spread out among the mountain hills where sibilant pines and wild grass make out the dominating vegetation, all presents a very exciting panorama. Merapi is located about 30 km north of Yogyakarta, a city with a population of 500,000. It is tall (2.8 km or 1.7 miles high) and has steep slopes.
The top of the volcano sometimes has a normal crater, but usually a broad mound of pasty lava (called a dome) fills the crater. The dome plugs up the volcano, making it difficult for other lava and ash to escape. A broad gouge funnels lava and ash flows from the top of Merapi to the south slopes of the volcano.
During its resting time of volcanic activities, it will enable those who have much interest in mountaineering to have fun and to make them more acquainted with the flora of its tropical rain forest. From the observation post located on Plawangan hill that can be reached through the forest resort of Kaliurang, we will see the incredible sights of molten rocks oozing over the rim, sometimes accompanied with hot lava pouring out regularly and leaving a long trail of smoke.
