# Tornadoes of 1970

This page documents the tornadoes and tornado outbreaks of 1970, primarily in the United States. Most tornadoes form in the U.S., although some events may take place internationally.

### January 1 (Australia)

An intense tornado, which occurred near the town of Bulahdelah (100 kilometres (62.1 mi) north-northeast of Newcastle), New South Wales on 1 January 1970, is thought to be the most destructive tornado ever documented in Australia. It is thought to have reached F4 intensity on the Fujita scale, however, no official rating has been made public. The tornado left a damage path 22 kilometres (14 mi) long and 1–1.6 km (0.6–1 mi) wide through the Bulahdelah State Forest. It is estimated that the tornado destroyed over one million trees. A caravan was destroyed and a 2-ton (2,000 kg) tractor was lifted into the air, landing upside down. The tornado was reported by witnesses as a swirling black cloud surrounded by flying debris, and producing a thunderous roaring sound. The weather system that produced the tornado was a classic set-up for violent tornadoes, something somewhat rarely seen outside of the United States, Canada, Bangladesh, and adjacent areas of India.
