Impact of Volcanic Eruption
The first is how the weather near an erupting
volcano is being affected. The second is how large eruptions will affect the
weather/climate around the world. I think more people are worried about the
second issue than the first. As far as we know, the main effect on weather
right near a volcano is that there is often a lot of rain, lightning, and
thunder during an eruption. This is because all the ash particles that are
thrown up into the atmosphere are good at attracting/collecting water droplets.
Another problem in Hawaii is that involves the formation of volcanic fog. The
ongoing eruption is very quiet, with lava flowing through lava tubes and then
into the ocean.
Volcanoes affect people in many ways, some are
good and some are not. Some of the bad ways are that houses, buildings, roads
and fields can get covered with ash. As long as you can get the ash off
(especially if it is wet), your house may not collapse, but often people leave
because of the ash and are not around to continually clean off their roofs. If
the ash fall is really heavy it can make it impossible to breathe.
Positive Impact
The main good effect that volcanoes have on the
environment is to provide nutrients to the surrounding soil. Volcanic ash often
contains minerals that are beneficial to plants, and if it is very fine ash it
is able to break down quickly and get mixed into the soil.
