# List of earthquakes in 1928

This is a list of earthquakes in 1928. Only magnitude 6.0 or greater earthquakes appear on the list. Lower magnitude events are included if they have caused death, injury or damage. Events which occurred in remote areas will be excluded from the list as they wouldn't have generated significant media interest. All dates are listed according to UTC time. It was an active year with several events leading to deaths. Worst affected were Chile, Turkey, Bulgaria and the Philippines. Oaxaca, Mexico and Puno Region, Peru sustained several large earthquakes with the former seeing four reaching above magnitude 7.0. In spite of a series of earthquakes, only four deaths were caused in Mexico during the year.
