WHAT CAUSED IT?

THE PLATES MOVING BACK AND FORTH. EARTHQUAKES WERE CAUSED BY FAULT MOVEMENT PREDICTED BY THE CONTINUED RELEASE IF STRESS AT THE SURFACE FROM THE RETREAT OF GLACIERS.

What effects did it have on society?The Mississippi river flowed backward for

a time as result of the earthquake. All the buildings were destroyed to ruble by the violent shake of the earthquake. It also poses a threat to health, safety, and economic viability. The death tolls were small since it was not a big city. The whole city was flooded.

How far did it affect?Previous 200 years have been aftershocks.

Due to the harder, colder, drier and less fractured nature of the rocks in the Earth’s crust in the central United States. Earthquakes in the region shake and damage an area approximately 20 times larger that earthquake in California in and most seismic areas.

How did society recover?

THEY REBUILT BUILDINGS. MANY PEOPLE MOVED AWAY FROM NEW MADRID THINKING THAT ANOTHER 7.6 MAGNITUDE WOULD HAPPEN. THE RESIDENTS OF NEW MADRID REBUILT WITH LOTS OF OUTSIDE HELP.

AFTER THE NEW MADRID EARTHQUAKE

How would it affect us?

Pompeii Volcano (Mt. Vesuvius)

What caused it?What scientists detected was a tear in the

African plate. That allows heat from Earth’s mantle layer melt the rock of the African plate. The plate build’s up pressure and causes explosive eruptions. Mt. Vesuvius has had a 20 year eruption cycle. But the last serious eruption was in 1947.

What effects did it have on society?Most people died in a statue form. The air

burned their lungs and contracted and quickly turned in to statues, that are still preserved today. An estimated 20,000 people died.

How far did it affect?13 miles away did lava and ash spray all the

way to Herculaneum and a little near Naples. It destroyed all of their properties and buildings.

How did society recover?Pompeii was slowly recovering from a major

earthquake that rocked the city in February of A.D. 62. The shallow quake of Pompeii has now been turned into a tourist site for everyone.

Before and After Pompeii Volcano

Pompeii Volcano

Mount Pinatubo, Philippines

What caused it?A series of earthquakes that lasted over two

weeks caused Mount Pinatubo to erupt. The eruption occurred on June 15, 1991 and it was considered to be the largest volcanic eruption on the 20th century. The effects of the eruption were felt worldwide.

What effects did it have on society?847 People Killed - 300 from collapsing

roofs , 100 from the mud flows known as lahars, the rest from disease in the evacuation centers including measles.

•650,000 workers lost jobs•$700 Million Damages•1.2million people lost homesElectricity went off, water was

contaminated, road links were destroyed, and telephone links were cut.

How far did it affect?On March 15, 1991, a succession of earthquakes

was felt by villagers on the north-western side of the volcano. Further earthquakes of increasing intensity were felt over the next two weeks, and it became clear some kind of volcanic activity was imminent. On April 2, the volcano awoke, with prelatic eruptions occurring near the summit along a 1.5 km long fissure. Over the next few weeks, small eruptions continued, dusting the surrounding areas with ash. Seismographs recorded hundreds of small earthquakes every day. 

How did society recover?Two decades after the eruption of Mount

Pinatubo, the Aetas remain in need of help. They started rebuilding their buildings. The affect still remains today.

Before the Eruption

After the Eruption

What if one of the volcanoes on the big island of Hawaii became active?

How could it happen?A volcano is a week spot in the crust where

molten material or magma reaches the surface. Magma is a mixture of rock-forming substances, gases, and water from the mantle. When magma reaches the surface it turns to lava and spews out.

What effects would it have on society?Some of the effects are good and bad. The

bad would be houses, buildings, roads, and fields would be covered with ash and burned down. Lots of people would die because if you breathe in the ash, smoke, and if lava consumes you of any of your body.

How far would it affect?The effect of an eruption, would effect nearby

cities but nothing to bad. Atmospheric conditions may carry ash away from the city or top a graphic may direct lahars and pyroclastic flows to unpopulated areas.

What recommendations would you give for recovery?Sweep up as much ash as possible. Have

people pick up debris, and rebuild houses and building, and help each other out.
