(CNN) -- A magnitude 5.1 earthquake shook parts of Indonesia Sunday morning, including areas decimated by an earthquake and tsunami in 2004.The temblor struck at 5:56 a.m. local time (5:56 p.m. Saturday EST), according to the U.S. Geological Survey. The U.S.G.S. said the quake was centered in Northern Sumatra region and occurred at a depth of about 25 miles (40 kilometers).
A 5.1 magnitude quake is considered moderate, but the center's location was only about 40 miles (65 km) from Banda Aceh. This region of Indonesia suffered near-total devastation in December of 2004, when a massive, magnitude 9 earthquake triggered tsunamis that battered coastlines around southern Asia.
The combined toll from the quake and the tsunamis topped 200,000, with most of them in Indonesia.
