Discover the wind speeds required to lift a house, typically seen in severe tornadoes like EF-2 or higher, causing catastrophic damage.
75 views
Wind speeds required to lift a house significantly vary depending on the house's structure and foundation. However, it generally takes extreme wind speeds, such as those from an EF-2 tornado (111-135 mph) or higher, to physically lift a house. These conditions are far beyond typical strong winds and suggest the presence of a severe weather event capable of causing catastrophic damage to communities.
