Emergency Net on 7.110 MHz
“A tsunami alert has been issued after a 7.4 magnitude earthquake struck off the northwest of Indonesia‘s Maluku Islands.
The tremor was measured 83 miles (134km) from the port city of Ternate at a depth of 30 miles (45km), according to the US Geological Survey.
Indonesia’s Meteorology and Geophysics Agency issued a tsunami alert following the quake, which hit roughly equidistant from the islands of Sulawesi and Halmahera.
Stephen Hicks, a seismologist at Imperial College London, said: “Fortunately, it has occurred offshore and at a reasonably deep depth so risk of damage from shaking and tsunami is low.””
