How Big Was The Asteroid That Struck North Sea & Led To 330-Feet Tsunami In Europe? Asteroid impact formed Silverpit crater, ending 20-year debate Impact triggered a 330-ft tsunami across Europe Asteroid was about 160 metres wide, size of a football field The impact triggered a mega-tsunami exceeding 100 metres in height. (AI generated for representation) An asteroid roughly 160 metres or 525 feet wide, which is as big as a football field, struck the North Sea 43 to 46 million years ago, creating the 20-kilometre-wide Silverpit crater, according to Science Daily. The impact triggered a mega-tsunami exceeding 100 metres in height, following the discovery of “shocked” quartz and feldspar that confirmed the origin of the crater. For two decades, experts debated whether the North Sea’s Silverpit crater was formed by a 43-million-year-old asteroid impact or, as voted in 2009, by geological salt movement. The debate concluded in 2025 following the discovery of shock-deformed minerals and 3D imaging confirming an impact event, invalidating the salt-withdrawal theory. According to recent reports in Science Daily and research published in Nature Communications, the asteroid that struck the North Sea was approximately 160 metres (525 feet) wide or as big as a football field. Researchers identified “shocked” quartz and feldspar crystals in rock samples from a nearby oil well. These microscopic minerals contain deformation patterns that only form under the extreme shock pressures of a high-velocity space impact. The asteroid struck the seabed at a shallow angle from the west, instantly blasting a 1.5-kilometre-high curtain of rock and water into the air. As this wall of debris collapsed, it triggered a mega-tsunami exceeding 100 metres (330 feet) in height.#silverpit_crater #nature_communications #asteroid_impact #north_sea #science_daily
Asteroids Smashed Off Hull's Coast, Triggering Mega-Tsunami Taller Than Big Ben Scientists have confirmed that a massive asteroid impact 40 million years ago created a colossal tsunami off the Yorkshire coast, generating waves over 100 meters high—taller than the iconic Big Ben clock tower. The discovery, published in Nature Communications, resolves a long-standing debate about the origin of the enigmatic Silverpit crater, located 700 meters beneath the seabed near Hull. The asteroid, approximately 160 meters in diameter, struck the North Sea region, leaving behind a well-preserved impact crater and a wave that surged across the ancient seabed. Researchers used advanced seismic imaging and samples from an offshore oil well to analyze the site, uncovering rare "shocked" minerals like quartz and feldspar. These microscopic crystals, formed under extreme pressures only possible during violent cosmic collisions, provide definitive proof of the asteroid impact. The Silverpit structure, first identified in 2002 as a three-kilometer-wide crater surrounded by circular faults, had long been the subject of scientific controversy. Some experts speculated it could have formed from underground salt deposits or volcanic activity, while others argued for an asteroid strike. A 2009 study rejected the impact hypothesis, but recent findings have conclusively overturned those doubts. Dr. Uisdean Nicholson of Heriot-Watt University, who led the research, described the evidence as "beyond doubt." His team combined seismic data with mineral analysis to confirm the crater’s origins. According to their models, the asteroid approached from the west at a shallow angle, displacing a 1.5-kilometer-high wall of seawater and debris.#silverpit_crater #heriot_watt_university #asteroid_impact #imperial_college_london #north_sea
