416 AD

Earliest known eruption of Krakatoa, described as a " thundering noise and a fiery glow in the sky." Heavy storms and rain took place, earthquakes and tsunamis likely took place.
There is no geological evidence of a Krakatoa eruption of this size around that time, but it is proven as there was tectonic activity between islands.
535 AD

Eruption that possibly led to the 535-536 AD Global Climate Change, a rapid change in Earth's climate. The event is caused by a atmospheric dust veil, dropping the temperature, blocking of sunlight and causing many social devastations such as droughts and crop failures.
It also may be responsible for the creation f the islands, Verlaten, Lang and Rakata.

A time, where the Dutch were in control of Indonesia for their variety in spices, mainly pepper. Krakatoa was installed with a few pepper plantations and naval stations. Generally, the Dutch ignored Krakatoa.

The next eruption of Krakatoa responsible for a great storm and several Earthquakes at sea, accompanied by crackling and thunder. Also, a plumage of excessive ash and pumice, resulting in a sulphuric atmosphere.
May 20th 1883 - August 27th 1883

A time where an devastating eruption took place. Preceding the catacylmic eruption, a series of lesser eruptions took place in May 20th.
May 20th- A series of miniscule Earthquakes took place. These earth quakes were most likely due to seismic activity in the tectonic plate. It portrays a scene were the plates were converging, troubling continents as there was friction created, arising Earthquakes. The residents were somewhat worried, but most could not relate this to a catastrophe. The oceanic plane was troubling as waves were rapidly increasing in size and quantity. The vents were overpowering with steam, and subtle explosions could be heard from distant islands.
June 11th- Eruptions could be heard again, and ash piles were exceeding limits. Due to this, black clouds were spotted in the atmosphere, blocking out the sun, and lowering temperatures.
June 24th - Ash columns were seen above the volcano, and the depth of the ocean was unusually high. Many ships had hold anchor, as a series of earthquakes followed and large amounts of pumice were seen hovering on the ocean.
August 11- A serious period of time, where ash was piling rapidly on Krakatoa and small eruptions took place. A sign of storms brewing was considered. At this time the sea level was incredibly high, and ships around Krakatoa were suffering.
August 25- Explosions amplified and the ash cloud rose, allowing the volcano to be in paroxysmal stage. The rate of eruptions increased and a storm took place. Later, a tsunami swept up the shores of Java and Sumatra.
27 August-four enormous explosions took place at 05:30, 06:44, 10:02, and 10:41 local time. At 5:30 am, the first explosion was at Perboewatan volcano, triggering a tsunami heading straight to Telok Betong, now known as Bandar Lampung. At 6:44 am, Krakatoa exploded again on Danan volcano, with the resulting tsunami stretching eastward and westward. The largest explosion, at 10:02 am, was so violent that it was heard 3,110 km away in Perth, Western Australia, and the Indian Ocean island of Rodrigues near Mauritius, 4,800 km away, where they were thought to be cannon fire from a nearby ship
The final eruption created a pressure wave that rotated around the globe 3.5 times, endangering ears and destroying many villages.
