Question

Activity 3: Hazards From the US Geological Survey: "Volcanic ash consists of tiny jagged particles of rock and natural glass blasted into the air by a volcano. Ash can threaten the health of people and livestock, pose a hazard to flying jet aircraft, damage electronics and machinery, and interrupt power generation and telecommunications. Wind can carry ash thousands of miles, affecting far greater areas and many more people than other volcano hazards. Even after a series of ash-producing eruptions has ended, wind and human activity can stir up fallen ash for months or years, presenting a long-term health and economic hazard." Ash fall will blanket whatever is below it, such as this house from Papua New Guinea: 3.1. Ash falls like snow, but is made up of rock, which is much heavier than water. Ash fall can weigh up to 2.7 g/cm3, or 2700 kg/m3. Assuming the roof is approximately 20 square meters in size, and the ash fall is a meter thick, what is the total weight of the ash, in kg? What might happen to the house if ash continues to fall?

Explanation / Answer

3.1

Density = mass/ volume

mass of ash = Density of ash x volume of the area

mass of ash = 2700 x 20 x 1

mass of ash = 54,000 kg

If ash continues to fall then there are chances that the roof will collapse.

3.2

The flight of an aircraft across the Atlantic Ocean, from Europe, Africa or the Middle East to North America, Central America, South America, or vice versa is known as transatlantic flight. Therefore, these flights suffers the most and most of them will cancel. And this zone will become a no-fly zone

If any plane flies through ash cloud then the visiblity will become nill in ash cloud and apart from this the ash debris can destroy the plane too by their impact or because of high drag force developed when plane flies through these areas.

3.3

Mexico City, Puerto Varas, Puerto Montt, various Japanese cities and cities in northern Europe are effected by ash cloud at some time in their history. Its various effects are:

People gets stranded or unable to board flights.

Airlines lost billion dollars in missed revenues.

Emerging market currencies tied to tourism such as the Kenyan shilling and Turkisjh lira fell.

Hotels received fewer incoming tourists,

3.4

muscovite formula is KAl3Si3O10(OH)2

and orthoclase feldspar is KAlSi3O8

The only element is present in ash is Potassium hence using volcanic ash as fertilizer is not a very good idea.
