Earthquakes

2004 Indian Ocean earthquake

★

Indian Ocean tsunami(undersea
earthquake) of 2004, tsunami that
hit the coasts of several countries
of South and Southeast Asia in
December 2004.

★

It was caused by the convergent
plate boundaries.

★

The tsunami killed at least 225,000
people.

Earthquakes

2010 Haiti earthquake

★

2010 Haiti earthquake, large-scale
earthquake that occurred January 12,
2010, on the West Indian island of
Hispaniola, comprising the countries of
Haiti and the Dominican Republic

★

It was caused by the convergent plate
boundary

★

The initial shock registered a
magnitude of 7.0 and was soon followed
by two aftershocks of magnitudes 5.9
and 5.5.

Volcanic Eruptions

1815 Mt. tambora eruption

★

Mount Tambora, Indonesian Gunung
Tambora, volcanic mountain on the
northern coast of Sumbawa island,
Indonesia, that in April 1815 exploded in the
largest volcanic eruption in recorded
history.

★

It was caused by the convergent plate
boundary

★

Before its eruption Mount Tambora was
about 4,300 metres (14,000 feet) high. After
the eruption ended, a caldera spanning
some 6 km (3.7 miles) across remained.

Volcanic Eruptions

1883 eruption of Krakatoa

★

Krakatoa, Indonesian Krakatau, volcano
on Rakata Island in the Sunda Strait
between Java and Sumatra, Indonesia.
Its explosive eruption in 1883 was one of
the most catastrophic in history.

★

It was caused by the convergent plate
boundary

★

From its base, 1,000 feet (300 metres)
below sea level, the cone projected
about 6,000 feet (1,800 metres) above
the sea.

Island Formation

The Formation of kauai

★

Kauai, Hawaiian Kaua‘i, volcanic
island, Kauai county, Hawaii, U.S.
It lies 72 miles (116 km) northwest
of Oahu island across the Kauai
Channel.

★

It was caused by the
convergent plate boundary

★

Kauai has Hawaii’s only
consistently navigable rivers.

Mountain Range

Andes

★

Andes Mountains, also called the Andes,
Spanish Cordillera de los Andes or Los
Andes, mountain system of South America
and one of the great natural features on
Earth.

★

It was caused by the subduction plate
boundary

★

The Andes consist of a vast series of
extremely high plateaus surmounted by
even higher peaks that form an unbroken
rampart over a distance of some 5,500 miles
(8,900 kilometres)

Fault Line

San Andreas

★

San Andreas Fault, major fracture of the
Earth’s crust in extreme western North
America

★

It was caused by the transform plate
boundary

★

According to the theory of plate tectonics,
the San Andreas Fault represents the
transform (strike-slip) boundary between
two major plates of the Earth’s crust: the
Northern Pacific to the south and west and
the North American to the north and east.

Mid Atlantic Ridge

IceLand

★

Mid-Atlantic Ridge, submarine ridge lying
along the north-south axis of the Atlantic
Ocean; it occupies the central part of the
basin between a series of flat abyssal
plains that continue to the margins of the
continental coasts

★

It was caused by the divergent plate
boundary

★

Iceland was founded more than 1,000 years
ago during the Viking age of exploration
and settled by a mixed Norse and Celtic
population.
