California, Oregon, Washington, Alaska and the Canadian province of British Columbia could all be affected, the National Tsunami Warning Center said in a bulletin.

Kabar Medsos – A tsunami advisory has been issued for Hawaii and parts of the U.S. Pacific coast after an undersea volcano erupted in spectacular fashion near Tonga on Saturday.

California, Oregon, Washington, Alaska and the Canadian province of British Columbia could all be affected, the National Tsunami Warning Center said in a bulletin.

Residents living near beaches, harbors, marinas and other coastal areas should move away from the shore and make their way inland or uphill, the bulletin added.

The Berkeley Fire Department in California ordered a “mandatory evacuation” of the marina area Saturday morning, warning of waves up to 3 feet by 7:30 a.m. local time.

In Hawaii, the Pacific Tsunami Warning Center reported waves slamming ashore from a foot in Nawiliwili, Kauai, to 2.7 feet in Hanalei.

The advisory was issued after Hunga Tonga Hunga Ha’apai volcano erupted near Tonga early Saturday, sending strong waves crashing onto its main island, Tongatapu.

The eruption lasted 10-15 minutes and threw ash plumes over 8 miles high, according to the Tonga Geological Services.

A convoy of police and military troops evacuated Tonga’s King Tupou VI from his palace near the shore following the eruption, the Islands Business news site reported. He was among the many residents who headed for higher ground.

Scientists observed massive explosions, thunder and lightning near the volcano after it started erupting early Friday, the Matangi Tonga news site reported.

It was the latest in a series of eruptions seen in the region since early Friday.

More than 1,400 miles away in New Zealand, officials were warning of storm surges from the eruption. The National Emergency Management Agency said some parts of country could expect “strong and unusual currents and unpredictable surges at the shore.”

New Zealand’s military also said it was monitoring the situation and remained on standby, ready to assist if asked.

Tsunami advisory warnings have also been issued for parts of Australia where waves several feet high have been observed on Norfolk Islands off the country’s east coast.

Large waves have also been observed in Vanuatu and other South Pacific nations.


Peringatan tsunami dikeluarkan untuk Pantai Barat AS setelah letusan gunung berapi bawah laut

California, Oregon, Washington, Alaska dan provinsi British Columbia di Kanada semuanya dapat terkena dampaknya, kata Pusat Peringatan Tsunami Nasional dalam sebuah buletin.

Kabar Medsos – Peringatan tsunami telah dikeluarkan untuk Hawaii dan sebagian pantai Pasifik AS setelah gunung berapi bawah laut meletus secara spektakuler di dekat Tonga pada Sabtu.

California, Oregon, Washington, Alaska dan provinsi British Columbia di Kanada semuanya dapat terkena dampaknya, kata Pusat Peringatan Tsunami Nasional dalam sebuah buletin.

Penduduk yang tinggal di dekat pantai, pelabuhan, marina, dan daerah pesisir lainnya harus menjauh dari pantai dan berjalan ke pedalaman atau menanjak, buletin itu menambahkan.

Pemadam Kebakaran Berkeley di California memerintahkan “evakuasi wajib” di area marina Sabtu pagi, memperingatkan gelombang setinggi 3 kaki pada pukul 07:30 waktu setempat.

Di Hawaii, Pusat Peringatan Tsunami Pasifik melaporkan gelombang menghantam pantai dari satu kaki di Nawiliwili, Kauai, hingga 2,7 kaki di Hanalei.

Peringatan itu dikeluarkan setelah gunung berapi Hunga Tonga Hunga Ha’apai meletus di dekat Tonga Sabtu pagi, mengirimkan gelombang kuat menerjang ke pulau utamanya, Tongatapu.

Letusan berlangsung 10-15 menit dan melemparkan gumpalan abu setinggi lebih dari 8 mil, menurut Layanan Geologi Tonga.

Sebuah konvoi polisi dan pasukan militer mengevakuasi Raja Tonga Tupou VI dari istananya di dekat pantai setelah letusan, situs berita Islands Business melaporkan. Dia termasuk di antara banyak penduduk yang menuju ke tempat yang lebih tinggi.

Para ilmuwan mengamati ledakan besar, guntur dan kilat di dekat gunung berapi setelah mulai meletus Jumat pagi, situs berita Matangi Tonga melaporkan.

Itu adalah yang terbaru dari serangkaian letusan yang terlihat di wilayah tersebut sejak Jumat pagi.

Lebih dari 1.400 mil jauhnya di Selandia Baru, para pejabat memperingatkan gelombang badai dari letusan. Badan Manajemen Darurat Nasional mengatakan beberapa bagian negara bisa mengharapkan “arus kuat dan tidak biasa dan gelombang tak terduga di pantai.”

Militer Selandia Baru juga mengatakan sedang memantau situasi dan tetap siaga, siap membantu jika diminta.

Peringatan peringatan tsunami juga telah dikeluarkan untuk beberapa bagian Australia di mana gelombang setinggi beberapa kaki telah diamati di Kepulauan Norfolk di lepas pantai timur negara itu.

Gelombang besar juga telah diamati di Vanuatu dan negara-negara Pasifik Selatan lainnya.
