Not Dangerous at all!
It has been in news recently that the Volcano erupted in small episodes of about five to ten minutes, on January 23, 2017. It resulted into the ash clouds and red lava fountains were ejecting from the crater and the hot lava flowed streaming down its slopes. But don’t worry this is nothing new to this unique place. It has erupted at least five times over the next 100 years.
Historically, the first record of the volcano’s eruption dates back to 1787. In 1991, it erupted so and the smoke billowed out for about six months. And since then there have been eruptions every two-three years also the last in February 2016.
However, all of these eruptions lie at the lowest level of the Volcanic Explosivity Index. This index ranks the volcanoes from 1-8 on the basis of quantity of volcanic material spewed and its strength. This latest 2017 eruption was recorded as a 2 on the index which is much in the safe limits.
