In light of the hazards that Merapi poses to populated areas, it was designated as one of the Decade Volcanoes. Another large eruption occurred in 2006, shortly before the Yogyakarta earthquake. A pyroclastic flow from a large explosion killed 27 people on 22 November 1994, mostly in the town of Muntilan, west of the volcano. Smoke can often be seen emerging from the mountaintop, and several eruptions have caused fatalities. It is located approximately 28 kilometres (17В mi) north of Yogyakarta city which has a population of 2.4 million, and thousands of people live on the flanks of the volcano, with villages as high as 1,700 metres (5,577В ft) above sea level. It is the most active volcano in Indonesia and has erupted regularly since 1548. Mount Merapi, Gunung Merapi (literally Fire Mountain in Indonesian and Javanese), is an active stratovolcano located on the border between the province of Central Java and the Special Region of Yogyakarta, Indonesia. 7-14.Mount Merapi, colour lithograph, Junghuhn and Mieling, 1853вЂ“1854 Гўв‚¬Е“Analisis Durasi Hujan Dominan dan Pola Distribusi Curah Hujan Jam-Jaman di Wilayah Gunung MerapiГўв‚¬.

Spatial mapping results show similar pattern of distribution where the maximum rainfall position is located in the west side of Mount Merapi.ДЇeng, W.C., & Chen, W.L. The results showed that the average rainfall or maximum rainfall for duration of 1 hour - 8 hours mostly occurred in the daylight until afternoon, between the hours of 13:00 to 17:00 with the incidence of heavy rain occurred in a short duration that is on the duration of 1 hour, 2 hours, 3 hours and 4 hours. Rainfall spatial variability was mapped based on the results of interpolation of the maximum rainfall data by Inverse Distance Weight (IDW) method, while the temporal variability was analyzed based on the average rainfall data distribution or maximum annual rainfall of each duration by unisolated event method. This paper will analyze the spatial and temporal variability of rainfall in the area of Mount Merapi.

This is important because of Indonesia is passed by the equator, so the rainfall variability is very high.

Therefore, it is necessary to analyze the characteristics of rainfall, such as variability in terms of space (spatial) and time (temporal). In the event of cold lava flood, where the rainfall as the trigger, there is a process of transformation of rainfall into the flow. Rainfall intensity is one of the main trigger factors of cold lava flow on the active volcano slope, such as Mount Merapi.
