- volcanoes
- (Nevada del Ruiz eruption 1985)
- As pyroclastic flows erupted from the volcano's crater, they melted the mountain's glaciers, sending
four enormous lahars down its slopes at 50 kilometres per hour (30 miles per hour). The lahars
picked up speed in gullies and coursed into the six major rivers at the base of the volcano; they
engulfed the town of Armero, killing more than 20,000 of its almost 29,000 inhabitants. It was the
nazcar plate going under the aztec plate. After a lahar demolished her home, Omayra Sánchez
became pinned beneath the debris of her house; she remained trapped in water for three days. Her
plight was documented as she descended from calmness into agony. Her courage and dignity
touched journalists and relief workers, who put great efforts into comforting her. After 55 hours of
struggling, she died, likely as a result of either gangrene or hypothermia

- general infomation
- The dictionary definition of a volcano is:
a mountain with a large, circular hole at
the top through which lava ( hot liquid
rock) gases, steam, and dust are or have
been forced out
- What is dangerous about a volcano?
The major dangers of earthquakes
are destroyed houses, buildings, and
businesses and lead to injury and loss
of life. This in turn causes major
challenges to the community's
economic and social status.
- Are there going to be earthquakes near you?
Earthquakes usually tend to happen in areas
located on or close to the boundaries of
tectonic plates. The effects plates shifting and
sliding against each other are felt along these
boundaries. In addition to earthquakes,
volcanoes and mountain ranges usually form
along these weak areas in the earth's crust.

- earthquake
- (earthquake in japan 2011)
- The powerful 8.9 earthquake off the coast of Japan that
triggered a damaging tsunami along 250 miles of Japan's
coast. On March 11, 2011, the world watched in horror
as video and photos showed a wall of water roaring
inland as far as six miles, carrying away cars and people
and levelling towns. Three years later, the recovery
remains slow and painful. About 270,000 victims are still
displaced, according to the Seattle Times. Children living
in the vicinity of the damaged Fukushima Daiichi
nuclear power plant are still not supposed to be outside
more than 15 to 30 minutes each day because of
radiation fears, NBC News reports. People are still
searching from their loved ones, including a man
who learned to scuba dive so he could look for his wife's
body.

- droughts
- Drought case study Kenya (2009)
- More than one million Kenyans risk facing hunger because of a
prolonged drought. The lack of rains has caused crops to fail and
cattle-herders are also struggling to keep their animals alive. The
worst affected areas are in the country's semi-arid south-east
regions as well as some parts of central Kenya. The World Food
Programme (WFP) has described the crisis as a "very difficult
situation" and appealed to donor countries to offer funds.
Currently some 2.5 million people are receiving emergency food
aid in the country but the effect of the drought has meant that a
further 1.3 million now also need help."People are saying it is the
worst drought since 2000," said WFP spokeswoman Gabrielle
Menezes. The regions affected normally harvest their crops once a
year, planting them in April and collecting in September after the
rains. But this year those rains have failed to come.
