Ocean rift zone spreads crust rapidly

Ocean rift zone experienced a sudden burst of crustal spreading. New data reveals most spreading occurred in a short window, with some events lacking seismic activity. This suggests a rapid process of magma intrusion and seafloor formation. The event, monitored in 2024, generated an estimated 150 million cubic meters of new material, equivalent to 38 years of average spreading.
