2. An
inactive volcano is called a dormant. An
inactive volcano/dormant becomes active
again when pressure builds up in the mantle,
or when the plates open back up again
It would bring a lot of the world together to
help. Everybody in the world would here
about the eruption of the volcano. All the
people on the big island would probably be
devastated and depressed of there loss.
3. The
magma/lava would probably cover most
of the island. The eruption would burn a lot
of the trees and houses on the big island.
The lava would spread into the water an
make the island bigger.
To recover they would have to rebuild on the
parts of the island that were not hit.
Evacuate people from parts of the island that
were not hit. Collect the items that survived
the eruption.
4. Erupted
in Sunda Strait, Indonesia on August
27, 1883
Killed 36,000 people and destroyed 165
villages and destroyed 2/3 of the pre-existing
island of Krakatoa
Ash fell on 840km north, 1155km SW, 6076km
west- northwest
Could be heard 3,000 miles away
The ocean water had gotten into the
volcano’s magmatic chambers through its
rupturing walls leading to the formation of
superheated steam
5. It
lasted 3 days long
The remaining island is named Rakata
Only a small islet remained in a basin
covered by 900 feet
Buried under a thick layer of sterile
ash/animal life did not begin to reestablish
itself for 5 years
Volcano’s collapse triggered a series of
tsunamis
Afterwards rebuilt villages
6.
Cabusilin Mountains, Luzon, Phillipines.
Last eruption was June 15, 1991.
It was dormant for 500 years before erupting in 1991.
It is thought there was a much bigger eruption 35,000
years ago.
Mount Pinatubo is an active stratovolcano .
The volcano spewed a more than 1 cubic mile column
of ash 22 miles
The ash circled around the world and lowered the
global temperature 1 degree for the next few years.
One of the biggest eruptions of the 20th century.
The island of Luzon went dark after the eruption.
7. 15.1417
N, 120.3500 E
The Aeta people , who lived on the slopes
of the volcano were hit the hardest, and
had to evacuate , when they came back
the villages were destroyed and the
government had to relocate them.
The eruption scored a 6 on the VEI
(Volcano Explosively Index) meaning it
was colossal, extremely large.
Over 700 people died and 100,000 made
homeless
8. The
earthquake ruptured the north most 296
miles of San Francisco.
Its offset was 20 feet deep.
More than 3,000 people died, and more than
200,000 people were left homeless.
The earthquake affected 375,000 square
feet.
It had a magnitude between 7.7 and 8.3.
It was caused by 2 plates hitting each other.
