Environmental Impact of Recent Volcanic Eruption from Mt. Mayon over South-East Asia

Arpit Tiwari, Siddhartha Singh, Soni V.K, Ravi Ranjan Kumar

Volcanoes are the mountains that erupt metallic compounds in the form of Lava, dust and gases vulnerable to the environment. These erupted gases affect the physical and chemical characteristics of Aerosol particles present in the atmosphere by absorbing the incoming radiation from the sun. This process has a huge contribution towards instability of the Heat budget of the Earth and leads to global warming and climate change. Compounds of sulfur e.g. (H2S, C2S, SO4) erupted from a volcano have severe effect on climate by scattering the incoming sunlight back to the space and leads to increased cooling rate of the earth surface. In this paper; short term and immediate effects of volcanic eruption from Mayon volcano have been discussed. The recent eruption of Mt. Mayon at Albay, Philippines on 29th Jan 2018 affected huge vegetation and environmental impacts of this eruption are found up to Brunei and Sarawak province of Malaysia. The study revealed that outbound airmass patternss from Mt. Mayon had Southwest direction that carried Sulfur dioxide and ash plumes till Malaysia. The case study shows huge vegetation loss and sudden rise in SO2 concentration over Sarawak from 1st Feb 2018 to 4th Feb 2018.
