The Samoa Meteorology Services (M.E.T.) has assured the public that there is no immediate tsunami threat facing the country following the volcanic eruption in Tonga. 

However, a tsunami advisory is still in effect for Samoa and the public is also advised a marine advisory is also in effect due to winds of 25-35 kilometres per hour and waves of about 3.0 meters or more due to the current unstable weather conditions.

"Therefore, please be cautious near shorelines and in the waters as strong currents will be possible," a notice from the M.E.T. reads. 

"Tsunami advisory remains for all Samoa’s coastal areas due to fluctuations in tide levels but there is no immediate tsunami threat for Samoa.

"Due to these sea-level fluctuations the public is therefore advised to stay away from the coastal areas."

A tsunami watch that was activated late Saturday night was canceled 5.10am Sunday morning and got downgraded to an advisory threshold due to ongoing eruptions at the Hunga Tonga-Hunga Ha'apai volcano in Tonga.

"Tsunami-related information is in place for several Pacific island nations, parts of New Zealand, the east coast of Australia, and Japan.

The M.E.T. on Sunday distributed a threshold table for geological impacts in Samoa that advised of the words and their terminologies that are in use at this time. According to the table, an "advisory" means that members of the public should "be aware" that a distant earthquake or tsunamigenic event has occurred. A tsunami is possible and the public should stay tuned for more information and be prepared to take action if necessary.

The Samoa Observer has been unable to get updates on the twin volcanic eruption and tsunami disaster that struck Tonga on Saturday afternoon.

A violent eruption by the Hunga-Tonga volcano at around 5pm on Saturday local time that triggered a tsunami led to the loss of all telephone and internet communication. It is understood the Internet and phone lines went down at around 6.40pm, leaving the 105,000 residents in the kingdom uncontactable.

The volcanic eruption was so powerful it sent shockwaves around the world with sonic booms from the seismic activity on Saturday afternoon heard in Fiji, Samoa and New Zealand and as far afield as Alaska.
