History
The Krakatoa volcano erupted with cataclysmic effects on August 26, 1883. This was the largest eruption in a series of eruptions that began in May of that year. The eruption destroyed most of the island of Krakatoa.
Effects
Krakatoa's eruption spewed so much material into the atmosphere that weather patterns were affected for five years, dropping the global temperature of the planet. The collapse of the island into the ocean created tsunamis that killed 36,000 people.
Considerations
The Krakatoa eruption released as much energy as a 200-megaton atomic bomb and even though it occurred over a century ago, the site is still active. In 1927, marine eruptions were observed at the site of Krakatoa, creating a new volcano, Arak Krakatoa or son of Krakatoa.
