The mystery of Silverpit Crater, a giant crater hidden about 700 meters below the northern seabed, has been a fierce debate between scientists for more than two decades. Located about 80 miles from Yorkshire Beach, this crater first became a finding in 2002 by an oil geologist. Since its discovery, the main question that arises is whether this perfect circular structure is a trail from the impact of space or is it only the result of geological processes in general, for example a layer of salt moves in the earth’s crust?

The unique characteristics that silverpit have, such as a circular shape, the presence of a peak in the middle and a concentric crack pattern, immediately directing the hypothesis at high-speed cosmic collisions. However, a number of geologists argue that a simpler phenomenon, namely tectonic shifts and the movement of layers of salt, can explain the shape of the crater. This controversy triggered intensive research efforts to reveal the truth of the origin of the crater.

Initially, the silverpit crater estimated had a core diameter of 2 miles with a 12 mile circular crack zone. Its depth, based on bathymetry measurements and seismic data, reaches more than 500 meters. The structure of this complex concentric ring is considered similar to other collision craters on earth. Until, in turn strengthens the alleged event of a meteorite collision.
However, the significant difference in the geological composition of the region encourages some scientists to weigh the role of complex geological activities that are common in the northern sea. In a debate in the London Geological Society in 2009, the majority of participants actually supported the theory of salt movement. This shows a tendency to choose a more conservative and geological -based explanation. This reflects a big challenge in interpreting natural phenomena that rarely occur without any concrete physical evidence.
Modern seismic analysis strengthens the collision hypothesis
After years of debate, the puzzle about the origin of the mystery of the Silverpit Crater is now starting to find a bright spot. Recent research on Uisdean Nicholson‘s sedimentologist, Heriot-Watt University, Edinburgh, has provided the strongest evidence so far that supports the asteroid hypothesis.
The research team uses modern seismic mapping that allows them to see the crater structure in detail far more clearly than the previous data. In addition, there is also a microscopic examination of stone samples and computer simulations. The results of this comprehensive analysis show that the mystery of the silverpit crater is likely to be formed due to the impact of asteroids or comets in diameter of about 160 meters. This ancient collision estimated more than 43 to 46 million years ago, much younger than the initial estimate that had mentioned more than 60 million years.

Impact and significance of the discovery
The asteroid impact with a diameter of 160 meters, the size of a cathedral building, is not a small event. This incident is estimated to trigger a 100 meter tsunami wave for the ancient area. Even so, the scale is much smaller than the hit chicxulub 66 million years ago which triggered the extinction of dinosaurs. Well, the silverpit collision is certainly a major disaster for the life of ancient mammals for the region.
This finding is very significant scientifically. The mystery of the silverpit crater is the only location of the hit that is now part of the British. Estimated there are only about 200 confirmed grafts of the land and only 33 are on the underwater. Silverpit structure as one of the examples that are very well -dressed.
Rare event
According to experts, this kind of cosmic collision is a very rare event. More rarely can last millions of years due to tectonic and erosion activity. Therefore, research on silverpit is not only important to understand the event of cosmic collisions that have forming geological history. But it can also help scientists to predict the potential impacts that might occur if the asteroid again hit the planet in the future.

The journey to uncover the mystery of Silverpit Crater shows the complexity and challenges in understanding the history of the geology of the earth. The latest evidence of seismic mapping and in-depth analysis has now further strengthened the allegations. None other than the unique silverpit crater of the northern seabed is a trail of a mystery of ancient cosmic collisions. Nevertheless, further exploration and research still need to strengthen the conclusion, opening more secrets hidden by the subsurface of the ocean. (R10/HR-Online)
