Haiti, 2010: Overview

Marco, DestinyIt was a 7.0 magnitude earthquake.Death toll at 316,000.Strike-Slip Fault caused the earthquakeCaribbean and North American plates. Enriquillo-Plantain Garden Fault had not moved in 200 years building up pressure.

History of Disaster

• The island of Hispaniola which is shared by Haiti and the Dominican Republic is seismically active and has a history of destructive earthquakes.

• Earthquakes recorded by Moreau de Saint-Méry when Haiti was a French Colony happened in 1751, 1770 Port-au-Prince.

• Other towns in Haiti and the Dominican Republic were destroyed in May 1842.

• A 8.0 earthquake was recorded on August 1946, producing a tsunami that killed 1,790

Mt. Saint Helens

Mount Saint Helens Brittany & Hunter

Located in Skamania, Washingtonhttp://www.boston.com/bigpicture/2010/05/mount_st_helens_30_years_ago.html

• The mountain was estimated to start forming at around the early 15th century.

• It was generally formed by volcanic eruptions and flows over a long period of time.

Mount Saint Helens

Basically the Juan de Fuca plate is smashing up against the North American Plate and is sinking below it (It being a oceanic plate) which is allowing magma to rise up.

Eruption

• The eruption was preceded by a two-month series of earthquakes and steam-venting episodes.

• An earthquake on May 18, 1980 caused the entire weakened north face to slide away, suddenly exposing the partly molten, gas- and steam-rich rock in the volcano to lower pressure.

• The rock basically responded by exploding a hot mix of lava and pulverized rock toward Spirit Lake so quickly that it overtook the avalanching north face.

• All in all... epic.

Mount Pinatubo:

• Took place on the Island of Luzon in the Philippines

• A warning was sent out on June 5th, 1991 and then again on June 9th, 1991

1991 at 1:42 pm

• The eruption lasted for 9 hours

Mount Pinatubo:

• Up to 800 people were killed and 100,000 became homeless

• Tons of sulfur dioxide was discharged

• A decrease in temp. was a result of the discharge

• The eruption is known as the second-largest volcanic eruption of this century

Dust Bowl of the 1930's-Caused by over farming and overuse of the land.- A giant area of land in the southern plains during the 1930's was depleted of all the nutrients in the soil and caused giant dust storms. - The natural grasses were killed off. Drought and winds carried the the top soil away.

Northern Texas, Oklahoma, New Mexico, Colorado, Kansas

The sand and dust blew into the northern states

About the Dust Bowl

-The dust bowl lasted about a decade.

-Children went to school wearing masks and people put wet sheets over their windows attempting to keep the dust particles out.

Acts of the Dust Bowl

- May 1933, The Farm Mortgage Act: $200 million dollars to help refinance farmers- 1934 Great Dust storms spread to other states, covering and affecting over 75% of the country.- 1935, Soil Erosion Act - 1939, Rain finally comes and ends the drought

Farming Now

Smarter Farming:- Crop Rotation- Strip Cropping- Contour Plowing

Farmers were paid to practice these techniques
