A moderate 5.9-magnitude quake struck Indonesia's Sunda Strait early Sunday, but no tsunami warning was issued and there were no immediate reports of damage. 
The quake was at a depth of about 50 kilometers about (31 miles). Its epicenter was more than 170 kilometers west of the capital Jakarta.

On Saturday night, a moderate earthquake measuring 5.4 jolted Indonesia's Aceh province following the magnitude 8.5 earthquake on Wednesday afternoon. Aftershocks continued to be felt in Aceh following an 8.5 magnitude earthquake on Wednesday. Two massive earthquakes struck off Indonesia's Sumatra island last week, triggering an Indian Ocean-wide tsunami alert and sending terrified people fleeing from the coast.
