Worked Solution & Example Answer:Imagine you are a journalist sent to the site of a recent volcanic eruption - Junior Cycle Geography - Question b - 2021
Step 1
Loss of Life and Property
Answer
One significant negative impact of volcanic eruptions is the loss of life. For instance, the eruption of Mount St. Helens resulted in 57 fatalities as a direct consequence of the explosive activity. Additionally, the destruction of property in the vicinity leads to significant economic hardships for the affected communities.
Step 2
Environmental Consequences
Answer
Volcanic eruptions have profound effects on the environment. Trees within a 25 km radius of Mount St. Helens were flattened, and the eruption led to the melting of glacial ice and snow, which in turn created mudflows. These mudflows blocked waterways, disrupting local ecosystems and harming wildlife, including over 7,000 animals like deer and bear.
Step 3
Impact on Weather Patterns
Answer
Volcanic activity can also alter weather patterns. The gases and ash particles released into the atmosphere can prevent sunlight from reaching the Earth's surface, leading to a drop in temperature. This phenomenon can create acid rain, adversely impacting agriculture and forestry.
Step 4
Economic Repercussions
Answer
The economic impacts of volcanic eruptions cannot be overlooked. Following the eruption, approximately 12 million farmed fish were killed, and about 200 homes were destroyed. The infrastructure damage, such as the 300 km of roads needing repairs, places a heavy financial burden on the affected regions and communities. Furthermore, the destruction of forests diminishes resources for logging industries.
