U.S.A and Global Events for April 7th:

1926: Lightning started a disastrous oil fire at San Luis Obispo, California, which lasted for five days, spreading over 900 acres, and burned over six million barrels of oil. Flames reached 1000 feet, and the temperature of the fire was estimated at 2,500 degrees. The fire spawned thousands of whirlwinds with hundreds the size of small tornadoes. One vortex traveled one mile to the east-northeast of the blaze, destroying a small farmhouse and killing two people. Damage totaled $15 million dollars.
