The eruption of Mount St. Helens in 1980 was relatively short, lasting for about nine hours. However, the effects of the eruption, including the eruption column and pyroclastic flows, had long-lasting impacts on the surrounding area.
When there is a geological change, such as an earthquake or volcano eruption, it can cause shifts in the Earth's surface, leading to things like landslides, tsunamis, or the formation of new land formations. These changes can have both short-term and long-term impacts on the environment and ecosystem.
Mount Laki in Iceland was formed through a volcanic eruption in 1783. The eruption created a long fissure and produced large amounts of lava and toxic gases, leading to widespread environmental and societal impacts. The volcanic activity lasted for several months, ultimately resulting in the formation of Mount Laki and the surrounding landscape.
Mount Rainier's last known eruption occurred around 1,000 years ago, resulting in a debris flow that traveled down the White River Valley. The eruption event itself likely lasted for a relatively short amount of time, potentially several days to weeks.
The secondary effects of Mount Merapi's eruptions include widespread ashfall, which can damage crops, contaminate water supplies, and pose respiratory health risks to local populations. Additionally, volcanic gases can lead to acid rain, further harming the environment. The eruptions often cause displacement of communities, leading to social and economic challenges, including loss of livelihoods and increased strain on emergency services and infrastructure. Long-term ecological impacts may include changes in land use and soil composition in the affected areas.

Short term effects of an eruption include ashfall, pyroclastic flows, and lahars, while long term effects can include changes in the local environment, alteration of landscapes, and impacts on climate due to ash and gas emissions. Additionally, both short and long term effects can lead to displacement of communities, destruction of infrastructure, and economic losses.

Mining is a short-term activity with long-term effects. There can be no disproportionate concentration of investment on gold and diamond-seeking.

Short-term effects of bushfires include immediate loss of life, destruction of homes, habitat destruction, and air pollution from smoke. Long-term effects may include changes to ecosystems, loss of biodiversity, increased risk of erosion and flooding, and impacts on water quality. Additionally, there can be long-lasting psychological impacts on affected communities.
