SANTIAGO, Chile — A powerful magnitude-8.3 earthquake hit off Chile’s northern coast Wednesday night, causing buildings to sway in Santiago and other cities and sending people running into the streets.
At least four aftershocks above magnitude-6 and other strong shakes rattled the region as tsunami alarms sounded in the port of Valparaiso in the first major quake since a powerful quake and tsunami killed hundreds in 2010 and leveled part of a southern Chilean city.
The tremor was so strong that people on the other side of the continent, in Buenos Aires, Argentina, reported feeling it.
