The eruption of the Krakatau (or Krakatoa) on a
small island located in the middle of the Sunda Strait in
August 1883 was, in many aspects, the first global
catastrophe.
The news about the eruption, its following
tsunami and the more than 36,000 victims travelled fast
thanks to the recently installed worldwide telegraphic
network.

The effects of the eruption were also noted all around the world.
The final explosion of Krakatau produced the loudest
sound ever recorded in modern history, heard on over 10% of Earth's area.
Reports of a distant cannonade or what seemed to be gunfire were reported
from Australia and the island of Mauritius, more than 4,650 km distant from the
erupting volcano. The pressure waves travelled within a few hours several
times around the globe. Instruments measured the sudden peaks in
Britain as in America.

Krakatau produced an
eruption column between 25 and 43
miles high, visible by all ships passing the
Sunda Strait. Within two weeks the ash,
gases and aerosols were blown by
atmospheric winds westwards along the equator. Months after the
eruption the volcanic cloud spread from the equatorial to the mid-latitude
zones. The fine grains, trapped in the higher layers of earth's atmosphere, scattered the sunlight for many years
to come, causing strange optical phenomena, like blood-red skies.
Krakatau was the first scientifically well recorded and studied eruption of a volcano, from the very
beginning to its disastrous ending.
Unfortunately, nobody realized the real danger of Krakatau. As the island was uninhabitable it was
believed that it would pose no threat to human lives. Between August 26 and 27 a series of explosions almost
totally destroyed the volcano, causing a series of tsunami-waves that killed 36,000
people along the coasts of Java and Sumatra.
The story of Krakatau is still not over. In 1930, in the caldera formed by the
explosion and collapse of the old volcano a new one, Anak Krakatoa, the child of
Krakatau, started to grow. The child has grown fast, displaying a continuous activity
since its first eruption it rises by 16 feet per year and most probably will keep
growing.

Answer 1

Answer 1. A sudden outbreak of a volcano - eruption.

Translation 1: Un estallido repentino de un volcán = erupción.

Answer 2. Long and high sea waves chased by an earthquake or other disaster - tsunami.

Translation 2: Olas grandes y altas causadas por un terremoto u otro desastre = tsunami.

Answer 3. A line dividing the earth into northern and southern hemispheres - equator.

Translation 3: Una línea que divide la tierra en hemisferios norte y sur - ecuador. (imaginaria)

Answer 4. A large volcanic crater - caldera.

Translation 4: Un gran cráter volcánico: caldera.
