Las Vegas Motor Speedway
On October 16, 2011, the final race of the 2011 IndyCar season, the IZOD IndyCar World Championship, was held at Las Vegas. However, the race was halted by a horrific crash on lap 11 that involved 15 cars, some of which became airborne, and some of which burst into flames. The crash began when Wade Cunningham made light contact with James Hinchcliffe, but the situation turned into a big pile-up of cars. The crash allowed a red flag to be waved almost instantly, due to the remains of the damaged cars and the amount of debris on the track.

A 2018 study by Hameed et al. at the University of Aizu simulated the impact of a positive IOD event on Pacific surface wind and SST variations. They show that IOD induced surface wind anomalies can produce El Nino like SST anomalies, with the IOD's impact on SST being the strongest in the far-eastern Pacific. They further demonstrated that IOD-ENSO interaction is a key for the generation of Super El Ninos.
