![]() ![]() ![]() Years later, NOAA scientists discovered that this sound emanated from an iceberg cracking and breaking away from an Antarctic glacier. 'The Bloop' is the given name of a mysterious underwater sound recorded in the 90s. The quakes broke the soil and damaged the foundations of buildings and roads. The source of a mysterious rumble recorded in the ocean in 1997 is now known to have originated from an icequake. This file is super high pitch and your dog will hate you if you play this for too long. But it was loud enough to wake Boyd up at 4:30 a.m. It's not really loud, at least the ones I heard,' Boyd said. In 2016, Oulu in Finland experienced a rash of frost quakes, as 26 hit the sub-Arctic environment within a seven-hour window. Super high pitch dog whistle sound effect for 30 seconds. 'It's like an explosion but a muffled boom sound. This revealed that a rapid decrease in temperature can cause thermal stress strong enough to shatter a soil-ice combo, resulting in the bangs and cracks we’ve observed following frost quakes. They used a hydrological model to calculate snow depth, snow melt rate, and soil temperature at different depths in the soil and explore what happens when the temperature suddenly changes. ![]() Thermal stress is related to the stress created by any change in the temperature of a material that causes it to expand and contract, such as the impact of freezing water in saturated soil. To do so, researchers established a model that enabled them to investigate the connection between thermal stress and frost quakes. Recent reports from frosty regions like Finland, Canada, and the US have demonstrated the damage these quakes can cause to infrastructure, so it’s a weather phenomenon worth getting to know if we’re going to keep safe during increasingly unpredictable conditions. ![]()
