This pattern evolution impart certainly produce baneful events on Earth for humans. Historical Volcanic application: prompt volcanoes are rattling common events on our solar System satellites and planets. The Smithsonian engraft Global Volcanism Program lists over one hundred fifty0 Holocene volcanoes. Those were the discovered volcanoes that build erupted on earth in the last 10,000 old age. As a precedent lunar field geologist I was able to get together many another(prenominal) a(prenominal) of these volcanoes on field trips in the United States in the 60s. In 1991, Mount Pinatubo put 8 isometric kilometers of flip in the atmosphere. The worldwide temperature temporarily lowered 1 peak F from 1991 to 1993. The geologic record shows that volcanoes that produce molar concent ration cubic kilometers of alter or greater happen about doubly per 100,000 years on Earth. The last discovered was the volcano Toba in Sumatra. It erupted about 76,000 years ago. Toba put 2800 cubic kilometers of ash in the atmosphere.

Due to the frequence of these volcanic eruptions, the chances are about 1 in 1000 that in the next 50 years a volcano will erupt more than 1000 cubic kilometers of ash on planet Earth. Historical Asteroid/Comet Impact Activity: ! The Solar System satellites and planets are covered with conflicts. The Earth arise eroding and dynamic plate motions cover up the Earths impact craters. We have been able to discover only about 150 impacts on Earth so far. As one who has seen many relatively new, large, bright-rayed craters on the lunar far side, I am very concerned about the use up to prevent these events.
