Explanation:
The island of Krakatau is located in Sunda Strait between Java and Sumatra. It is part of the Indonesian Island Arc. Volcanic activity is due to subduction of the Indo-Australian tectonic plate as it moves northward toward mainland Asia. The Krakatoa island is found to be about 3 miles wide and 5.5 miles long (9 by 5 kilometers). As at the time of this eruption in 1883, the region was part of the Dutch East Indies; it’s now part of Indonesia. Location: Krakatoa, Anak Krakatau Island, Pulau, South Lampung Regency, Lampung, Indonesia, Asia.
In August 1883, the eruption of Krakatoa, (or Krakatau), was one of the most deadly volcanic eruptions of modern history ever recorded. It is estimated that more than 36,000 people died. The deaths recorded were as a result of the thermal injury from the blasts. Also, the victims were of the tsunamis that followed the fall of the volcano into the caldera below sea level. The temperatures dropped all over the world and the climate was affected because the eruption was so terrible.
This is because June 21st marks the astronomical start of summer for the northern hemisphere with the summer solstice. During this season the days are longer than the nights, and as we get closer to the North Pole, we will have up to 24 hours of sunlight, a phenomenon called the Midnight Sun.
This is possible because during the summer solstice, due to the tilt of the Earth's axis, the North Pole is closer to the Sun than the South Pole. However, paradoxically the Earth is at its furthest point from the Sun (aphelion).
That is why on June 21st, the sun is visible for 24 hours and the next days (the closer it is to the north pole) it will stay that way. Therefore, the inhabitants of this area can enjoy sunlight for a longer period.
