Although the average tornado that comes through Massachusetts is rated EF0 or EF1, the state is not immune to the tremendous powers of higher-rated storms. On June 9, 1953, an EF4 tornado ripped through Worcester County. The tornado lasted 84 minutes, tore through 10 towns, including Shrewsbury, Holden and Petersham before weakening and roping out in Westborough. That tornado killed 94 people and injured 1,250 more. The death total of that storm makes it the 20th deadliest tornado in United States history. It should be noted that a second tornado touched down that same day, leaving a path of destruction from Mendon to Mansfield in 67 minutes.
