Shield volcanoes Main article: Shield volcano Shield volcanoes‚ so named for their broad‚ shield-like profiles‚ are formed by the eruption of low-viscosity lava that can flow a great distance from a vent‚ but not generally explode catastrophically. Since low-viscosity magma is typically low in silica‚ shield volcanoes are more common in oceanic than continental settings. The Hawaiian volcanic chain is a series of shield cones‚ and they are common in Iceland‚ as well. Lava domes Main article:

The Volcanic Eruption of Nevado Del Ruiz Nevado Del Ruiz located in Central Colombia‚ is a broad‚ glacier covered volcano. A relatively small eruption caused a devastating mud flow that killed almost 25‚000 people in the town of Armero‚ marking one of the worst volcanic disasters in history. Sadly‚ this tragedy could have been easily avoided if clear warnings by volcanologists had been taken seriously. On November 13‚ 1985‚ Nevado Del Ruiz erupted and created a lahar.

Mount St. Helens proves to be a memorable landmark to all Americans and still a source of fascination today for a variety of persons. Mount Saint Helens‚ an active stratovolcano‚ is located in southwest Washington State. The volcano erupted on May 18th‚ 1980 at 8:32 a.m. The eruption was triggered by a 5

What actually causes the majority of deaths is not the lava‚ but rather the intensely hot gas that rushes down the sides of the volcano at an incredible 60 miles per hour‚ obliterating anything in its path.

by volcanoes around the world (40 marks) A hazard is defined as something which has the potential to kill or cause harm. However a hazard is only a risk to people if they are exposed to it. This is when a hazard can cause disasters. For example‚ a volcano is only a hazard if the population comes in contact with the consequences of its activity. Hazards and their likeliness to become disasters can depend on many different factors‚ for example how developed a country exposed to the hazard is‚ the size

that fall into a pile around the vent. The pile forms an oval-shaped small volcano‚ as shown in this picture. During each eruption‚ hot molten lava was ejected into the air from a vent. It cooled‚ solidified‚ and fell back to earth as ash‚ cinders‚ popcorn-sized particles (“scoria”)‚ and larger “bombs” as much as three feet in diameter. The larger‚ heavier material accumulated around the vent to build a cone-shaped volcano with a crater depression in the centre. These ejected materials will settle

on increased activity on the volcano. However‚ in 1978‚ Dwight Crandell and Don Millineaux of the USGS suggested that Mt. St. Helens was potentially the most likely volcano to erupt in the twentieth century; based their evidence on the relatively young age of the volcano‚ and its frequent historical eruptions (Explore). Since about 1400 A.D.‚ eruptions have occurred at approximately one every 100 years. Before the 1980 eruption‚ it had been 130
