Question

Which of volcanic eruption or earthquake cause the most impact to humans. Explain your answer.

Answer 1

Earthquakes and volcanoes cause damage not only to humans and their structures, but to the environment and wildlife. Earthquakes can cause damage by shaking,  tsunami’s, and landslides. Volcanoes can cause damage by ash flows, release of gases, mudflows, lava flows, and landslides.

Earthquakes may be associated with volcanic hazards, especially as a precursor to an eruption. However, earthquakes can cause disasters without the help of a volcano. Earthquakes generate seismic waves that can release great energy. But if the earthquake occurs in an area that is not populated, it is not a human disaster.

Volcanic damage occurs because of the products generated by an eruption. The type of eruption is important. For instance, a quiet lava eruption gives human enough time to evacuate an area. Violent eruptions that occur with little warning are sometimes difficult to avoid. Many people do not believe that volcanoes can cause much damage, and refuse to move.

Volcanoes erupt differently, depending on the composition and thickness of the erupting lava, the amount of gas in the parent magma, and force of the eruption. Volcanoes that erupt lava that is low in silica and gases tend to be "quiet," mostly pouring out streams of fairly fluid lava. Kilaeua volcano in Hawaii is a good example. Volcanoes that erupt silica-rich magmas, and that have a lot of gas, tend to be explosive. This produces tremendous clouds of volcanic ash, ash flows, and gases. The loose material produced by these eruptions often becomes the raw material for landslides or mudflows. can cause dangerous explosions as well as gentle lava flows.

Answer 2

volcanic erution. it has been confirmed to be the cause of ice age.

Answer 3

volcanic eruption.

it causes the loss of lives, property,and it causes acid rain, air pollution and ultimately,global warming

Answer 4

A volcanic eruption can cause immediate and severe damange to a specific area.  Google "Pompei"

An earthquake can cause major damage to a much broader area.  When the earth moves, it can not only bring down all the buildings around the epicenter causing major damage and killing many people, but it can also cause very severe ocean waves like the one around Christmas a few years ago.

Answer 5

cheating won't help you.

atleast do some research.

Answer 6

Of the types of Volcanic eruptions or the ones that have occured in history? Pyroclastic eruptions are the greatest threat because they can cause near instant death and cost many lives. For earthquakes it depends on the intensity level and the magnitude. Earthquakes can cause great damage. The most deadly amongst Volcanoes might be the eruption of Mount Pelee (Spelling?) near Martinique killing 30,000+ instantly. Earthquakes have killed tens of thousands more than that, a more recent one near Pakistan(not sure, somewhere near there) killed close to 80k. Hard to say.
