Taiwan issues tsunami alert following 8.8-magnitude Russian earthquake
Taiwan issues tsunami alert following 8.8-magnitude Russian earthquake
2025-07-30
An 8.8-magnitude earthquake off Russia’s Kamchatka Peninsula triggered a tsunami alert in Taiwan on Wednesday. You would think that the warning would get people away from the coast, but that was not the case. Curious thrill-seekers headed to coastal areas of Taiwan in the afternoon, when the tsunami waves were supposed to hit Taiwan. Fortunately, the waves were mostly less than 10 centimeters tall and did not cause any mishaps.
The beach is a popular summer destination. But on Wednesday, Jhongjiao Visitor Centre in New Taipei kept broadcasting a safety announcement.
It’s all because of an 8.8-magnitude earthquake off Russia’s Kamchatka Peninsula, which struck at 7:25 in the morning Taiwan time. Immediately afterwards, the Central Weather Administration issued a tsunami warning for coastal areas.

Almost the entire eastern coast is covered in cliffs, so it’s not so easy for tsunamis to form and build up. Whereas in the southwest, the ocean depth varies from deep to shallow, so there’s a greater chance of a tsunami building up.
Tsunami waves were estimated to be 0.3m to 1m high. In the afternoon, the Central Weather Administration announced their observed values.

It’s almost zero in Hualien, meaning there wasn’t much of a difference. As I mentioned, tsunamis don’t really build up in the east. Meanwhile in Su’ao, we’ve observed tsunami waves almost 9cm tall. In Kaohsiung, there was also a 1-to-2cm difference in tsunami wave heights.
Despite the alert, some people went fishing at Tainan’s Jiangjun fishing harbor braving rough seas that could’ve easily swallowed them up.
Meanwhile, at Hualien’s Qixingtan Scenic Area, some hobbyist photographers had planned to capture the Milky Way, but changed their mind and came to the beach when they got the alert.

I hope there will be stunning natural scenery.

In rainy Taitung, many passers-by also appeared to stop over for tsunami sightings, even though they probably shouldn’t. Fortunately, no casualties were reported.

台灣史上第三次海嘯警報 地震中心觀測"海嘯波<10cm"
2025-07-30
俄羅斯堪察加半島外海，上午發生規模8.8的強烈地震，儘管距離台灣4千多公里遠，氣象署也發布海嘯警報，下午1點多開始影響台灣。地震中心下午說明觀測結果，本島的海嘯波都沒高於10公分，只有蘭嶼測得12公分，地震中心在下午5點10分解除海嘯警報。
夏天不少人來到海邊，週三中角灣遊客中心不停廣播，提醒民眾注意安全。
原來是因為上午7點25分，俄羅斯堪察加半島外海發生規模 8.8強震，氣象署也隨即
台灣沿海發布海嘯相關訊息。

“台灣東部幾乎都是懸崖峭壁區域，所以對於海嘯形成、堆高的效果是不太容易的。在西南部這一邊，海水的深度是從深到淺，所以比較有機會能造成海嘯堆高。”
台灣沿海地區，預估海嘯浪最高落在0.3公尺到1公尺之間，氣象署下午公布觀測結果。

“(花蓮潮位測站)幾乎是接近0，(浪高)沒有什麼太大變化，因為東部我剛剛提過，能讓(海嘯)堆高效果不大。(東北部測站)蘇澳這邊有觀測到，接近9公分的海嘯波(堆高效果)。 (西南部測站)高雄這邊，大概有1到2公分左右的海嘯波變化。”
但在警報解除前，還是有民眾到將軍漁港釣魚，只見浪打上來，差點要把人吞沒，場面相當驚悚。
至於東部的花蓮七星潭，有攝影愛好者原本計畫要拍星空銀河，收到海嘯警報訊息，提前來到海邊。

“希望有令人驚艷的自然景象。”

“我們就在後面這邊而已。”
下著雨的台東，也有不少民眾經過海邊時，停下腳步想觀看海嘯景象，讓人捏把冷汗，所幸這一回海嘯，沒有傳出災情。
