There is also the flow of lava, which when people come into contact with kills them almost instantly. Volcanic ash: The after effects of volcanic eruptions are also bad. Lahars: Volcanic ash which when mixed with water or snow also tends to create large mud slides known as lahars. One such volcanic activity is another natural phenomenon presenting itself as subject of study and thereby adding to the body of knowledge. A volcanic eruption is formed when there are cracks or weaknesses in the earth’s crust through which magma rises up and when due to external forces or pressure such as the movement of tectonic plates this magma explodes to the surface creating a volcanic eruption. Inhalation of volcanic ash can be very detrimental to human health, due to the harmful aerosols and poisonous gases the ash is made up of. Respiratory symptoms (short-term) 1. runny nose 2. sore throat/coughing 3. wheezing/shortness of breath 4. possible bronchitus2.
