How to reach the crater
There are some choice to reach the crater or caldera of Mount Tambora:
Start the trip using airplane from Mataram to Bima (35 minutes), continued from Bima by car to Doropeti on south side of Tambora to the location of Volcano observation (5 hours).
by car from Mataram to Kayangan Port and cross to Alas with Ferry until Pototano Port. Then continue to Doropeti (15 hours).
To reach the lips of caldera, the climbing activities can be done from many side, such as:
From west, Calabai village and Pancasila village until west Caldera, this is general way, it needs 2-3 days.
From North, Kawind nae village untill north Caldera, it is shorter and fast from the forest but it is climb from the beginning until the top of the mountain.
From the noth-west, Doropeti vellage to the east untill west caldera and north west calseera. It is pass the woods where there are “jelatang” or “maladi” , the plant which hurt our skin when it touched.
From south, Doropeti, 12 km to east. It will pass the road to the north and climbing from PT. BA palantation until south caldera, with one day trip. This way is passing the dry savanna. But if we use car we can reach until 1200 mdpl in 3 hours, then continued on foot in 3-4 hours. (Heryadi & Iqbal, Mount Fire,West Nusa Tenggara)
A big Volcano that erupted in the 19th century
The paroxysmal eruption of Mt. Tambora on the island of Sumbawa in April 1815 – despite having triggered a world wide historic event – is astonishingly neglected in studies of volcanic activity. The world wide event referred to was the so-called “Year without a Summer” – the exceptionally cold months of 1816. In addition to this, Mt. Tambora’s eruption far-eclipsed in violence and ejecta the more famous eruption of Krakatau (Krakatoa) in 1883, which also had an impact on the world’s weather.
Though disappointing, the reason for part of this neglect is not hard to find. There exist few contemporary records of the eruption and what there is has seen little reprinting in modern works. Nonetheless, enough data is now available that a more definitive study can and should be undertaken. The intent of this posting is to synthesize and integrate what is available and hopefully inspire further investigation.
