CEBU (Updated) -- Another shallow earthquake, but with greater magnitude of 6.6, shook parts of Mindanao Tuesday morning, October 29, 2019.

The quake struck at 9:04 a.m. 25 kilometers southeast of Tulunan in Cotabato, the Philippine Institute of Volcanology and Seismology (Phivolcs) said in an advisory.

It was plotted in the same area as the October 16 quake that killed seven people and damaged several structures and infrastructure facilities. The previous tremor, with magnitude of 6.3, was centered 22 kilometers southeast of Tulunan, at a depth of eight kilometers.

Phivolcs said aftershocks and damage to properties are also expected this time, as the tectonic quake was also shallow, with a depth of only seven kilometers.

No tsunami warning has been issued, added Phivolcs.

The quake was felt in Davao City and Cagayan de Oro City, where residents rushed into the streets and open spaces in panic.
