Top 10 States for EF1 Tornadoes

Geographic distribution shows which states are most affected by EF1 tornadoes, highlighting tornado-prone regions.

EF1 Tornadoes by Decade

Distribution across decades shows long-term patterns and historical trends in EF1 tornado occurrences.

The increase in recorded tornadoes since the 1950s reflects both improved detection technology and possibly climate factors. Weaker tornadoes were often missed in early decades before modern radar and storm spotter networks.

Path Length Distribution of EF1 Tornadoes

Shows how far EF1 tornadoes typically travel, providing insights into their duration and geographic impact.

Fatality Distribution of EF1 Tornadoes

Shows the human impact of EF1 tornadoes, revealing what percentage caused fatalities and in what numbers.

Note: This chart uses a logarithmic scale to better show the distribution of fatalities, as most tornadoes cause zero deaths. Although most weak tornadoes don't cause fatalities, they can still be deadly when hitting vulnerable structures or populations.
