The United States Geological Survey (USGS) said that an underwater earthquake of magnitude 7.6 rocked Indonesia on Tuesday as the country’s meteorological authority issued a tsunami warning.
A magnitude 7.5 earthquake has been recorded off East Nusa Tenggara, Indonesia, in the Flores Sea.
Another seismological centre, the European-Mediterranean Seismological Center, put the magnitude at 7.7 and the earthquake depth at 5 kilometres.
The Pacific tsunami waves described as “dangerous” in the United States are also possible for coastlines within 1,000 kilometres of the earthquake’s epicentre in Indonesia.
“Recent earthquakes in this area have created secondary hazards such as tsunamis and landslides that might have contributed to losses,” the USGS noted, despite the low likelihood of casualties.
Due to Indonesia’s location on the Pacific “Ring of Fire,” an area of high seismic activity where tectonic plates meet, extending from Japan through Southeast Asia and throughout the Pacific basin, the country regularly experiences earthquakes and volcanic eruptions.
An earthquake of 9.1 magnitudes off the coast of Sumatra in 2004 generated a tsunami that killed 220,000 people in the region, including roughly 170,000 Indonesians, according to the United Nations Population Fund. According to some estimates, it was the deadliest natural disaster in recorded history.
The island of Lombok was rocked by a massive earthquake in 2018. Tremors continued for several weeks, killing more than 550 people on the resort island of Bali and Sumbawa, a neighboring province in Indonesia.
More than 4,300 people were killed or missing when a 7.5-magnitude earthquake and subsequent tsunami struck Palu on Sulawesi island in the same year.
