eruption of Krakatoa in 1883
Stato: Mali Anno: 1999 Notizie: Krakatoa is an island volano located along the Indonesian volcano arc between the islands of Java and Sumatra. In 1883 Krakatoa erupted in one of the largest eruptions in modern times. The explosion was heard as far away as Rodriguez Island, over 4,600 km away. Ash fell on ships over 6,000 km to the west-northwest. Tsunamis towered as much as 40 meters above sea level, levelling everything in their path. Over 36,000 people lost their lives, and 165 coastal villages were destroyed. Over two-thirds of the original island of Krakatoa sank below the sea. Unusual atmospheric effects such as blue and green suns as well as exceptionally vivid red sunsets were observed world-wide because of the dust and aerosol particles injected by the eruption into the upper atmosphere. The temperature world-wide dropped by as much as 1.2 °C and did not return to normal until 1888. Krakatoa is paired with the Pultusk meteorite. A shower of meteorites totalling about 400 kg fell near Warsaw in Poland on January 30, 1868 at about seven o'clock in the evening. Thousands witnessed a bright fireball followed by the shower of tens of thousands of small stones from Pultusk to Nowy. Perhaps as many as 100,000 individual stones fell, but only a few thousand have so far been recovered. Pultusk is classified as a stony H5 chondrite. |
