A 6.1 magnitude earthquake hits Indonesia

A 6.1-magnitude earthquake struck off the coast of Indonesia’s Sulawesi island Saturday, the United States Geological Survey said, but no tsunami warning was issued and there were no immediate reports of damage. The strong quake hit 258 kilometers (160 miles) northeast of the city of Manado in North Sulawesi at a depth of 68 kilometers.

Indonesia experiences frequent quakes due to its position on the Pacific “Ring of Fire”, an arc of intense seismic activity where tectonic plates collide that stretches from Japan through Southeast Asia and across the Pacific basin. The quake struck at 7.43 am (local time), with the epicentre at 112 km southwest of Melonguane city, Kepulauan Talaud district and the depth at 10 km under seabed.

The Ring of Fire, also referred to as the Circum-Pacific Belt, is a path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes. Its length is approximately 40,000 kilometers (24,900 miles). It traces boundaries between several tectonic plates including the Pacific, Juan de Fuca, Cocos, Indian-Australian, Nazca, North American, and Philippine Plates.

Seventy-five percent of Earth’s volcanoes more than 450 volcanoes are located along the Ring of Fire. Ninety percent of Earth’s earthquakes occur along its path, including the planet’s most violent and dramatic seismic events.
