Dating Nibiru (Planet of the Crossing) throughout history.

According to the Ancient Sumerians, Nibiru has an orbital pattern that is around 3600 years. This left me curious to know if 3500-3600 years ago there were any significant Earth-based disasters around that time. Calculate 2011-3600=1589 BCE(BC). What I found has been no less than shocking and further proof of a 3600 year cycle that occurs on this Planet.

What I found first:
[link to en.wikipedia.org]

1570 BC: Cretan palaces at Knossos and other centres flourish despite disasters.

This intrigued me so I attempted to find these particular disasters. Turns out it was during this particular time period a SERIES of disasters struck the planet leading to The Bronze Age Collapse.

Notable Disaster:
The Eruption of Thera

A little History:
The Minoan eruption on the island of Thera (present-day Santorini about 100 km(70 miles) distant from Crete) occurred during the LM IA period. The island of Santorini is the site of one of the largest volcanic eruptions in recorded history: the Minoan eruption (sometimes called the Thera eruption), which occurred some 3600 years ago at the height of the Minoan civilization. The eruption left a large caldera surrounded by volcanic ash deposits hundreds of feet deep and may have led indirectly to the collapse of the Minoan civilization on the island of Crete, 110 km (68 mi) to the south, through a gigantic tsunami. Another popular theory holds that the Thera eruption is the source of the legend of Atlantis.
