This eruption was the largest in at least 1,300 years (after the hypothesized eruption causing the volcanic winter of 536); its effect on the climate may have been exacerbated by the 1814 eruption of Mayon in the Philippines. The significant amount of volcanic ash and gases released into the atmosphere blocked sunlight, leading to global cooling.

This timeline of volcanism on Earth includes a list of major volcanic eruptions of approximately at least magnitude 6 on the Volcanic explosivity index (VEI) or equivalent sulfur dioxide emission during the Quaternary period (from 2.58 Mya to the present). Other volcanic eruptions are also listed.
In the years before the 1883 eruption, seismic activity around the Krakatoa volcano was intense, with earthquakes felt as far away as North Australia, one of which, in 1880, damaged a lighthouse. [4] Strombolian activity began on 20 May 1883, and steam venting began to occur regularly from Perboewatan , the northernmost of the island's three cones.
The eruptions continued for roughly two million years and spanned the Permian–Triassic boundary, or P–T boundary, which occurred around 251.9 million years ago. The Siberian Traps are believed to be the primary cause of the Permian–Triassic extinction event , the most severe extinction event in the geologic record.
A previous study focusing on the slopes of Sicily’s Mount Etna, an active volcano, found that goats – who are taking part in this study, too – became nervous before an eruption and would ...
There are only two planets in the solar system where volcanoes can be easily seen due to their high activity, Earth and Io. [34] Its lavas are the hottest known anywhere in the Solar System, with temperatures exceeding 1,800 K (1,500 °C). In February 2001, the largest recorded volcanic eruptions in the Solar System occurred on Io. [35]
The Kraffts were often the first to arrive at the scene of an active volcano, and became well known in the volcanologist community. [7] Their footage of the effects of volcanic eruptions on the surrounding areas often played a considerable part in gaining the cooperation of local authorities faced with volcanic threats.
