A new tremor struck two days after a magnitude 7.7 quake killed 53 people, injured 137 and displaced more than 5,000.

A magnitude 5.7 earthquake struck Indonesia’s Flores island on Monday, two days after a magnitude 7.7 quake killed 53 people, injured 137 and forced more than 5,000 people to evacuate. No tsunami warning was issued following the latest tremor.

The earthquake struck at 8:46 a.m. local time (0046 GMT) at a depth of 35.6 kilometers, with its epicenter 42.1 kilometers north-northwest of Ende, the island’s most populous locality, according to the U.S. Geological Survey (USGS).

Saturday’s magnitude 7.7 earthquake was centered 62 kilometers from Ende and triggered about 1,000 aftershocks, 46 of which were felt by residents.

The provincial government is seeking a decree declaring a 14-day state of emergency to help local and central authorities coordinate humanitarian assistance. More than 5,000 people displaced by Saturday’s quake are being housed in sports centers and other designated evacuation sites.

The latest earthquake struck as authorities continued assessing damage from Saturday’s quake. Infrastructure in the area had already been damaged by the earlier earthquake, while the succession of tremors has kept emergency agencies and residents on alert.

Flores is home to an estimated two million people. Ende, one of the island’s main cities, has about 90,000 residents.

Local authorities are continuing to assess the damage and assist affected residents. Further updates are expected on the impact of Monday’s earthquake and the condition of areas that remain without full connectivity.

Indonesia lies along the Pacific Ring of Fire, a zone of intense seismic and volcanic activity where about 7,000 earthquakes occur each year, most of them moderate in magnitude.
