This is a list of earthquakes in 2004. Only earthquakes of magnitude 6 or above are included, unless they resulted in significant damage or casualties, or were notable for some other reason. All dates are listed according to UTC time. The year 2004 had the most major earthquakes since 1999. In total, there were 16 magnitude 7.0+ earthquakes this year, 6 of them were in Indonesia. Most of the earthquake deaths in 2004 were caused by the magnitude 9.1–9.3 earthquake off the west coast of Sumatra in December. Most of the deaths were caused by a devastating tsunami that spread across the Indian Ocean. There were several other deadly and destructive earthquakes, including Morocco's largest earthquake to date, which caused 628 deaths. Japan was hit by a magnitude 6.6 earthquake, which caused 68 deaths and $28 billion in damage, making it the fourth costliest earthquake in history.

Compared to other years

Note that an increase in detected earthquake numbers does not necessarily represent an increase in earthquakes per se. Population increase, habitation spread, and advances in earthquake detection technology all contribute to higher earthquake numbers being recorded over time. USGS's Website has more information.
