when do volcanoes become dangerous?

We can call a volcano dangerous only when it causes damage to humans life. For instance, if a volcano erupts on the almost uninhibited East-asian peninsula of Kamchatka, it is hardly reported in the news. But, if a volcano starts spewing hot 🔥gases and ash in a densely populated area, many livies are risk. Explosive volcanic eruptions discharge huge quantities of dust and ash, often burying neibouring areas. Thin,dark megma can flow at a fast speed of up to 100 km/h marking it impossible to escape. Volcanic eruptions can also have far-reaching consequences. When the Indonesian volcano krakatau erupted in 1883,the volcanic ash reached up to a height of 80km, which for some time darkened the sky worldwide 🌐😀😄. 🌐.
