Pacific region prepares for small tsunami after Chilean quake
New Zealand cancels night-surf event: California, Hawaii expect small surge
Surfersvillage Global Surf News, 17 September, 2015 - A tsunami warning has been issued for Hawaii, California, New Zealand and throughout the Pacific following an 8.3 magnitude earthquake off the coast of Chile that forced millions to evacuate coastal areas in South America.
Predictions for New Zealand call for a wave surge of up to 1 meter (3 feet) for the northern Chatham Islands while smaller waves could hit the mainland after midnight Kiwi time.
According to 9News Australia, a night surfing event at Christchurch’s New Brighton Pier was called off due to the tsunami concerns. The event is sponsored by the Canterbury University Boardriding Association.
At least five people were killed in the South American country and a million people forced to flee.
Hawaii and part of California’s coast are under tsunami advisories as well.
The Pacific Tsunami Warning Center issued an advisory for Hawaii, according to US News, stating the main threat comes not from the wave itself, but from sea-level changes and dangerous currents that could pose a threat to those in or near the water.
An advisory means that strong currents and waves are possible in or very near the water. Currents may be dangerous for swimmers, boats, and coastal structures and may continue for several hours after the tsunami arrival.
In California the National Tsunami Warning Center issued an advisory that extends from San Onofre State Beach in San Clemente to Ragged Point, about 50 miles north of San Luis Obispo.
NOAA estimates the tsunami heights in California as follows:
Santa Monica: 0.8 feet
Middle Harbor (at the Ports of Los Angeles and Long Beach): 1 foot
Seal Beach: 0.8 feet
Huntington Beach: 0.7 feet
Newport Beach: 0.4 feet
Laguna Beach: 0.4 feet
Dana Point: 0.2 feet
Avalon: 0.1 feet
Two Harbors: 0.3 feet
Malibu: 0.6 feet
Port Hueneme: 0.5 feet
