Mount Merapi, located on the border between Central Java and the Special Region of Yogyakarta, Indonesia, is one of the most active and dangerous volcanoes in the world. Its name translates to 'Mountain of Fire', and it lives up to this title by erupting regularly, with significant eruptions occurring every few years. Standing at 2,930 meters tall, Merapi is a stratovolcano characterized by steep slopes and regular pyroclastic flows—hot gas and volcanic material that can rush down the slopes at high speeds, posing significant risks to nearby communities. Despite the dangers, the fertile slopes of Merapi are densely populated due to the rich volcanic soil that is excellent for agriculture. The volcano is also an important cultural and spiritual symbol, with local mythology personifying it as a kingdom of spirits. The most significant eruption of recent history occurred in 2010, causing widespread damage and fatalities. Nevertheless, the majestic peak of Merapi continues to attract hikers and tourists, drawn by its dramatic beauty and the challenge it presents to climbers.
