A 7.6-magnitude aftershock has rocked the same area of northern Chile where a massive 8.2 earthquake struck on Tuesday. The earlier quake, which caused a tsunami, killed six people and forced almost one million others to evacuate.

The Wednesday quake occurred just before 02:43 GMT off the northern coast of Chile, 19 km (14 miles) south of Iquique, according to the US Geological Survey (USGS). The epicenter of the latest quake was located at a shallow depth of 40 km (24.9 miles).

Chile’s emergency ministry has ordered a preventative evacuation along the northern Chilean coastline.

However there have been no official reports of damage or injury in Chile or Peru, according to Reuters.

A tsunami warning issued for Chile and Peru has been canceled, according to the Pacific Tsunami Warning Center.

“Based on all available data a destructive Pacific-wide tsunami is not expected,” it said earlier. However minor tsunami waves did hit the northern coast of the country.

Chilean President Michelle Bachelet has been evacuated from the Arica coast, local media has reported.

Aftershocks measuring magnitudes of 5.6 and 5.8 occurred after the 7.6 quake, according to the USGS. Both were located around 70 to 75 km (43 to 46 miles) southwest of Inquique.

Another strong aftershock, measured at magnitude 6.4, also struck 47 km (29 miles) west of Iquique at around 01:58 GMT Wednesday evening.

This comes one day after an 8.2 magnitude quake hit 95 km (59 miles) northwest of the same area, around Iquique.

After Tuesday’s quake, tsunami warnings spurred the evacuation of 900,000 people and 11 hospitals along the coastline, government officials said.

At least six people died following the quake, Chile's Interior Minister Rodrigo Penailillo said. Many of the victims died from heart attacks or falling debris.
