What was different about the explosion of Krakatoa?
21 October 1883 (?) The eruption was one of the deadliest and most destructive volcanic events in recorded history and explosions were so violent that they were heard 3,110 kilometres (1,930 mi) away in Perth, Western Australia, and Rodrigues near Mauritius, 4,800 kilometres (3,000 mi) away. …
What did the Krakatoa explosion sound like?
The atmosphere was ringing like a bell, imperceptible to us but detectable by our instruments. 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.”
What is the eruption style of Krakatoa?
Typical eruption style: Explosive. Construction of a cinder cone island (Anak Krakatau) inside the caldera formed by the 1883 eruption. Frequent strombolian activity.
What caused Krakatoa to explode?
It was the morning of August 27, 1883 that one of the world’s most astronomical eruptions occurred from the Krakatoa volcano. 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.
What was the cause of the eruption of Krakatoa?
WHAT CAUSED THE ERUPTION? 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. WHERE IS KRAKATOA?
How long did the Krakatoa explosion last for?
By the following morning – August 27 – Krakatoa’s three craters had been raging for more than 14 hours. Then starting at 5.30am came a series of four monumental explosions. The third of them, at 10.02am, was so loud that it was heard nearly 2,000 miles (3,200km) away in Perth, Western Australia, and 3,000 miles (4,800km) away in Mauritius.
What are the names of the islands in Krakatoa?
The caldera is part of a volcanic island group (Krakatoa Archipelago) comprising four islands: two of which, Lang and Verlaten, are remnants of a previous volcanic edifice destroyed in eruptions long before the famous 1883 eruption; another, Rakata, is the remnant of a much larger island destroyed in the 1883 eruption.
How tall was the tsunami that hit Krakatoa?
Krakatoa. However, the volcano’s collapse triggered a series of tsunamis, or seismic sea waves, recorded as far away as South America and Hawaii. The greatest wave, which reached a height of 120 feet (37 metres) and took some 36,000 lives in nearby coastal towns of Java and Sumatra, occurred just after the climactic explosion.
