Haitian President Michel Martelly called for residents to reflect Sunday on the devastating earthquake that swept through the small nation four years ago, killing tens of thousands and leaving scores of people homeless after it decimated buildings and houses, the Associated Press reports. The Haitian flag was flown at half-staff, and clubs were to remain closed.

Radio and television stations were encouraged to schedule programs and music for the occasion in honor of the victims, the report says. 

The 7.0-magnitude earthquake struck outside Haiti's capital on Jan. 12, 2010, destroying thousands of buildings in Port-au-Prince and surrounding cities. More than 300,000 died, officials say, but no one knows for certain how many people lost their lives.

The quake left 1.5 million people living in tent camps. Today, that number has dropped to 146,000, the report says.
