Pyroclastic flow

of the lower Columbia River that was published in 1798. Between 1831 to 1857 Mt. St. Helens was violently active and many settlers and local Indians in the area watched the steep-sided and symmetrical cone erupt explosively spewing layers of lava flows, ash, mud, steam, and other volcanic debris around the mountainous tranquil landscape. After each destructive eruption, the land recovered its natural beauty but was forever altered in its shape and…

Geologically, we can divide the outer core of the earth into two parts which are lithosphere and asthenosphere. Lithospheric shell contains a number of major breaks which can be referred as plate boundaries. Lithosphere sits on Asthenosphere, which is the portion of the mantle, causing the plates to move around as its solid and ductile properties. When we think about the movements of plate tectonics, we generally come up with the idea of dramatic natural disasters which destroy and derive…

The most significant event that took place on September 11 was when two hijacked planes, American Airlines Flight 11 and United Airlines Flight 175, crashed into the North and South towers of the World Trade Center in New York City.

The morning of August 24th 79 A.D. started out as any other day in Pompeii.

They did not know the dangers of the neighboring volcano and so believed themselves to be very lucky to find such a place. The city of Pompeii, in…

The volcano is part of the Pico de The volcano Parícutin is located in the volcanic fields in Míchoacan-Guanajuato.This volcano is also the greatest in both area. This volcano has not erupted since 1952. Also the elevation of the volcano is 9,186’. The volcano Parícutin was named by a nearby village of Parícutin. The volcano is the youngest of the approximately 1,400 volcanic vents of the Míchoacan-Guanajuato volcanic field. The volcanic field is 40,000 square kilometers (15,000 square miles).…

the case with earthquakes, monetization of a volcano is easily achievable. Mt St Helens was closely observed by satellites and therefore people were aware of the changes. They were therefore able to evacuate and 63 people died despite huge pyroclastic flows destroying vegetation up to 32km away from the volcano. However, the Japan earthquake in 2011 with a Richter scale of 9.0 had over 15,000 deaths however 99% of these were from the impacts of the tsunami which happened thirteen minutes…
