The Surigao del Norte earthquake struck at 22:03 on 10 February 2017. PHIVOLCS rated it magnitude 6.7. The epicentre lay about 16 km offshore, in the Surigao Strait, and Cagdianao felt Intensity V. Earlier that February an oarfish had washed up in Carmen, Agusan del Norte. Local belief holds that oarfish appear before earthquakes. The coast was already on edge.
