It’s the first time in almost 800 years we’ve had an eruption in this area. Volcanic eruptions are commonly preceded from days to months by an increasing volcanic tremor and substantial variations in near-surface radon concentrations at distances up to tens of kilometers from the events, especially when the summit part of the volcano and/or its flanks are interested by magmatic intrusions, deformations, and earthquakes (Cox et al., 1980; Cox, 1983).

Figure 1: Volcanic gas emissions breakthrough overlying … When plates collide, one plate is commonly driven beneath an-other (subduction). The enormous energy of volcanic eruptions can cause large landslides that move at speeds of more than 100 kilometers per hour (60 miles per hour). Some explosions were so loud that they could be heard throughout the island and even as far as neighbouring islands such as Adonara and Pantar. Earth’s orbital cycles may trigger peaks of volcanic eruptions 41,000-year cycle in the Earth's tilt matches up with peak volcanic activity.

Volcanic eruptions can also trigger global disasters, such as the eruption of the Yellowstone volcano 630,000 years ago, when large parts of North America were covered in ash. The Youngest Toba eruption was a supervolcanic eruption that occurred around 75,000 years ago at the site of present-day Lake Toba in Sumatra, Indonesia.It is one of the Earth's largest known explosive eruptions.The Toba catastrophe theory holds that this event caused a global volcanic winter of six to ten years and possibly a 1,000-year-long cooling episode.
