Magnitude 7.4 earthquake strikes in Indonesia, sparking tsunami alert (theguardian.com)

A magnitude 7.4 earthquake struck Indonesia’s Northern Molucca Sea region at a depth of 35km, with its epicentre about 127km west-northwest of Ternate. The US tsunami warning system said tsunami waves were possible within 1,000km of the epicentre, potentially reaching 0.3m to 1m above tide level in parts of Indonesia, while Japan, Guam, and other areas were warned of only slight sea level changes or no expected damage. Initial reports indicated strong shaking but no significant damage in Manado, North Sulawesi, and Japan’s meteorological agency said no tsunami damage was expected.
