Why was the eruption of Krakatoa the most explosive one in history?

the final explosions may have been caused by magma mixing: a sudden infusion of hot basaltic magma into the cooler and lighter magma in the chamber below the volcano. This would have resulted in a rapid and unsustainable increase in pressure, leading to a cataclysmic explosion.

How loud was the Krakatoa eruption?

(A 10-decibel increase is perceived by people as sounding roughly twice as loud.) The Krakatoa explosion registered 172 decibels at 100 miles from the source. This is so astonishingly loud, that it’s inching up against the limits of what we mean by “sound.”

Which volcanic eruption gave the loudest sound ever recorded?

Krakatoa
The loudest sound in recorded history came from the volcanic eruption on the Indonesian island Krakatoa at 10.02 a.m. on August 27, 1883. The explosion caused two thirds of the island to collapse and formed tsunami waves as high as 46 m (151 ft) rocking ships as far away as South Africa.

What is Krakatoa known for?

Krakatoa is a small volcanic island in Indonesia, located about 100 miles west of Jakarta. In August 1883, the eruption of the main island of Krakatoa (or Krakatau) killed more than 36,000 people, making it one of the most devastating volcanic eruptions in human history.

What were the effects of Krakatoa eruption?

During the next 24 hours, hot avalanches of ash raced down the volcano and across the sea. Most of the volcanic island collapsed into the ocean, triggering tsunamis and creating a giant underwater crater, or caldera. The eruption devastated surrounding islands and the coast of Java, causing over 36,000 fatalities.

What was the major factor that turned Krakatoa into a time bomb by the end of the 1800s?

Magma got lodged in the throat of the volcano and mixed with thick and thin magma, creating an explosive combination.

How did the Krakatoa eruption affect the global environment?

There was a lasting effect on the world’s climate, too: aerosols emitted into the atmosphere by the blast led global air temperatures to drop by as much as 2.2 degrees Fahrenheit (1.2 degrees Celsius).

What is the loudest man made sound?

The loudest sound ever created by humans, not by natural causes, was said to be the atomic bomb blasts over Nagasaki and Hiroshima. Those clocked in at around 250 decibels. NASA’s highest recorded decibel reading was 204 and that was the first stage of the Saturn V rocket.

Was Krakatoa heard around the world?

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.
