How many eruptions has Krakatoa had?

Thornton mentions that Krakatoa was known as “The Fire Mountain” during Java’s Sailendra dynasty, with records of seven eruptive events between the 9th and 16th centuries. These have been tentatively dated as having occurred in 850, 950, 1050, 1150, 1320, and 1530.

What is the maximum distance from Krakatoa at which the sound was heard?

On Aug. 27, 1883, just after 10 a.m., the eruption of the Krakatoa volcano in Indonesia made the loudest sound known to history — a terrifying roar that sent sound waves around the world four times and could be heard 3,000 miles away on the island of Rodrigues in the Indian Ocean.

Was the Krakatoa eruption sound recorded?

The explosion was loud enough that this level of noise was recorded many miles away from the site of the blast. A sound of 174 decibels was recorded by barometers 100 miles from Krakatoa. That meant anyone within an 100 mile radius of Krakatoa had a chance of being literally deafened by this sound.

What was the largest volcanic eruption ever?

Mount Tambora
The explosion of Mount Tambora is the largest ever recorded by humans, ranking a 7 (or “super-colossal”) on the Volcanic Explosivity Index, the second-highest rating in the index. The volcano, which is still active, is one of the tallest peaks in the Indonesian archipelago.

When did Krakatoa start erupting?

August 27, 1883
One of the most powerful volcanic eruptions in recorded history occurs on Krakatoa (also called Krakatau), a small, uninhabited volcanic island east of Sumatra and west of Java, on August 27, 1883.

How has Krakatoa erupted in the past?

Krakatoa is infamous for its violent Plinian eruption in 1883, that destroyed the previous volcanic edifice and enlarged its caldera. Collapse of the former volcanic edifice, perhaps in 416 AD, had formed a 7-km-wide caldera. Anak Krakatau has been the site of frequent eruptions since 1927.

Why did the Krakatoa volcano explode?

This eruption was caused by high pressure buildup in the two underlying tectonic plates. The resulting crack allowed for water to enter the volcano and mix into the magma cavity. This along with the extremely heated steam resulted in extremely intense pressure and an almost complete destruction of the island.

What is the loudest dB sound?

The Krakatoa volcanic eruption: Not only did it cause serious damage to the island, the eruption of Krakatoa in 1883 created the loudest sound ever reported at 180 dB.
