What was the name of the 2010 market crash that lasted about 36 minutes?

The 2010 market crash that lasted about 36 minutes was called the Flash Crash.

On May 6, 2010, U.S. stock indexes plunged rapidly before recovering much of the loss. The Dow Jones Industrial Average briefly dropped almost 1,000 points, then rebounded within minutes. Some individual securities experienced extraordinarily sharp and temporary price movements.

Investigations found that automated high-frequency trading and a large sell order contributed to the episode. A 2015 U.S. federal case concluded that trader Navinder Singh Sarao used spoofing orders that helped worsen the market disruption, although the event also reflected broader weaknesses in market structure.

The crash led regulators and exchanges to strengthen safeguards. Measures included circuit breakers, which temporarily halt trading after specified price declines, and later systems designed to limit extreme movements in individual stocks.
