After the 7.0 magnitude earthquake in January 2010, which country did the Navy assist?

The Navy provided significant assistance to Haiti following the devastating 7.0 magnitude earthquake that struck the country in January 2010. This earthquake had catastrophic impacts on infrastructure and the civilian population, resulting in a humanitarian crisis. In response, the U.S. Navy deployed ships, aircraft, and personnel to aid in relief efforts. This included delivering food, medical supplies, and other essential services to help the affected population recover from the disaster.

The other options refer to different events or locations: Fukushima relates to a nuclear disaster in Japan that occurred in 2011, Pakistan has experienced various aid efforts but not specifically related to this earthquake, and Japan, while a site of significant natural disasters, was not the focus of U.S. Navy assistance in January 2010. Therefore, Haiti is the correct answer, as it directly corresponds to the timing and context of the earthquake relief efforts by the Navy.
