Question 2

landslides + lahars

Answer 2

around 100 people died as they were engulfed by lahars in the 1991 mount pinatubo eruption.

the 1985 eruption of nevado de ruiz in the andes region of mountains released a pyroclastic flow which combined with glacial ice to form a lahar. the lahar engulfed the town of armero, killing more than 20 thousand people.

Question 3

pollution

Answer 3

the eruption of eyjafjallajokull, iceland produced extensive ash clouds that was carried by wind over thousands of kilometres to europe. this was a serious threat to aircraft engines and hence, air space over most of europe was closed and connecting flights were cancelled. 12 million passengers were delayed and around 1.8 billion usd was lost in the airline industry.
