Residents living in coastal communities are advised to stay away from the coast following a magnitude 7.5 earthquake that jolted Manay, Davao Oriental on Friday morning.

According to a tsunami warning issued by the Philippine Institute of Volcanology and Seismology (Phivolcs) at 9:53 a.m. the following provinces are expected to experience wave heights of more than 1 meter above the normal tides and may be higher on enclosed bays and straits:

  • Eastern Samar
  • Southern Leyte
  • Leyte 
  • Dinagat Islands
  • Surigao Del Norte 
  • Surigao Del Sur
  • Davao Oriental

Phivolcs said the first tsunami waves will arrive between 9:43 a.m. to 11:43 a.m. and may continue for hours.

“The people in the coastal areas of the following provinces are strongly advised to immediately evacuate to higher grounds or move farther inland,” it said.

Mariners are also advised to secure their boats and move away from the waterfront, while those already at sea “should stay offshore in deep waters until further advised.”

In its earthquake information bulletin updated at 10:12 a.m., Phivolcs said the tectonic quake struck 44 km northeast of Manay, Davao Oriental.

The offshore temblor had a depth of 20 km.
