New Zealand Assesses Tsunami Risk After Philippines Earthquake

A philippines earthquake of magnitude 7.8 struck near Mindanao at 11.37am, with the US Geological Survey putting the depth at 35km. The quake hit the southern end of the Philippine archipelago and quickly triggered tsunami monitoring beyond the Philippines.

New Zealand Tsunami Assessment

NEMA and GNS Science began assessing whether the earthquake had created a tsunami that could affect New Zealand. NEMA said, "If a tsunami has been generated in this location it is not likely to arrive in New Zealand for at least 10 hours."

NEMA also said, "This National Advisory has been issued following a rapid assessment of preliminary earthquake information. The situation may change as more information becomes available. We will provide an update when we have completed a further assessment." Christopher Luxon, the Prime Minister of New Zealand, was mentioned in relation to the government’s monitoring of the threat.

Pacific Tsunami Warning Center Advisory

The Pacific Tsunami Warning Center issued a tsunami advisory for the Philippines, Indonesia, Palau, Yap, Taiwan and Papua New Guinea. That advisory widened the immediate focus from the Philippine quake zone to several Pacific locations watching for possible wave impacts.

Mindanao is the Philippines’ second-largest and southernmost island group, placing the quake near the country’s edge rather than deep inland. The location, the depth and the size of the quake drove the rapid assessments now underway across the Pacific.

What New Zealand Is Watching

The practical next step for New Zealand is the further assessment NEMA said it will provide after reviewing preliminary earthquake information. The 10-hour timing estimate gives emergency planners a buffer, but the advisory shows the response is moving on limited initial data while the region checks for any tsunami generation.
