Which earthquake in 2010 had a magnitude of 8.8 and caused a tsunami across the Pacific?

The 2010 Chile earthquake was the magnitude-8.8 earthquake that generated a tsunami across the Pacific. It struck offshore central Chile on 27 February 2010, near the Maule Region, and is also known as the Maule earthquake.

This was a megathrust earthquake, produced as the Nazca Plate was forced beneath the South American Plate. The rupture lasted roughly three minutes and shook a large part of Chile, including the cities of Concepción and Santiago. Because the seafloor moved abruptly, the earthquake displaced ocean water and sent tsunami waves toward coastlines around the Pacific.

Tsunami warnings or advisories covered a vast area, including Pacific islands, New Zealand, Japan, and parts of North America. Coastal Chile suffered the worst tsunami damage, while waves also reached places such as Easter Island and Hawaii. The disaster caused 525 confirmed deaths and left hundreds of thousands of homes damaged.

The main confusion is with the 2010 Haiti earthquake, which was far smaller at magnitude 7.0, and the 2010 Mentawai earthquake in Indonesia, which measured 7.7. Neither matches the 8.8 Pacific-wide event described here.
