GEOLOGY

Detailed explanation-1: -In 1883, the world witnessed an event so loud that it was heard over 4, 800 kilometres away. The eruption of the Krakatoa volcano set a record for being the loudest sound in history. This volcanic island is located in the Sunda Strait between the Indonesian islands of Java and Sumatra, which laid dormant for centuries.

Detailed explanation-2: -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.

Detailed explanation-3: -The pressure wave generated by the colossal third explosion radiated out from Krakatoa at 1, 086 km/h (675 mph). The eruption is estimated to have reached 180 dB, loud enough to be heard 5, 000 kilometres (3, 100 mi) away.

Detailed explanation-4: -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.
