Asteroid Impact Created Silverpit Crater in North Sea, Triggering Massive Tsunami
Table of Contents
Recent scientific confirmation reveals that the Silverpit crater, located in the North Sea approximately 250 kilometers off the coast of the United Kingdom, was formed by a large asteroid impact. The impact, estimated to have occurred around 66 million years ago – coinciding with the Cretaceous-Paleogene (K-Pg) extinction event – unleashed a meaningful tsunami, perhaps reaching heights of 330 feet (100 meters).
Finding and Confirmation
the Silverpit crater was initially identified in the 1990s during oil exploration seismic surveys.though, its origin remained a mystery for decades. Scientists debated whether it was formed by volcanic activity, a salt dome, or an impact event. Recent research, utilizing high-resolution seismic data and core samples, has definitively confirmed the impact origin. The evidence includes a characteristic central uplift, disturbed rock layers, and shocked quartz – a mineral structure onyl formed under extreme pressure, such as that generated by an asteroid impact.
The Impact and Resulting Tsunami
The asteroid is estimated to have been approximately 400 meters (1,300 feet) in diameter. while significantly smaller than the chicxulub impactor (believed to have caused the K-Pg extinction), the Silverpit impact was still a substantial event. The impact created a crater roughly 3 kilometers (1.9 miles) in diameter and triggered a massive tsunami that radiated outwards across the North Sea.
