(CNN) A powerful 7.4-magnitude quake shook the Pacific coast of Central America on Tuesday, causing some damage and killing at least one person in El Salvador.

The quake was deep (70.5 kilometers or 43 miles) but close to El Salvador's shoreline -- about 64 kilometers from the municipality of Intipuca.
