On the fourth anniversary of the 2011 earthquake and tsunami in Japan, Democratic Progressive Party (DPP) Chairperson Tsai Ing-wen (蔡英文) issued a call for mobilization and participation in the nationwide antinuclear protests that took place on Saturday, calling it a concrete step on the way toward the goal of a nuclear-free homeland by 2025.
As Taiwan basically runs the same risks of nuclear disaster as Japan, we must learn from the past.
On March 11, 2011, at 14:46pm, there was a magnitude 9 earthquake in the western Pacific, off the coast of Fukushima on the east coast of Honshu, Japan’s largest island. Eleven reactors at four nuclear power plants in the region — Tohoku, Fukushima Nos. 1 and 2, and Tokai No. 2 — were operating at the time and were severely affected by the quake.
Although the external electricity transmissions to these power plants were severed by the earthquake, that did not have a direct effect on the key nuclear safety systems, equipment or installations at the Fukushima Dai-ichi plant.
However, the tsunami that followed brought 14m-high waves — far higher than the 5.7m defenses designed for the plant — destroying almost all the safety equipment at the plant and severely damaging the plant’s four reactors.
Japan is not the only country that has nuclear power plants in areas susceptible to earthquakes and tsunamis. Data from the World Nuclear Association show that 20 percent of the 433 nuclear reactors around the world are located in areas where earthquakes are a common occurrence.
In addition, many countries — like Taiwan — built their nuclear plants on the coast, because the cooling system of a reactor requires at least a billion gallons (3.79 billion liters) of water, perhaps more. However, all the power plants located along the coast are at risk of being hit by big waves or a tsunami.
The Fukushima Dai-ichi power plant accident taught us all a painful lesson by revealing the lack of preventive measures and planning for tsunamis and strong earthquakes. Specifically, it made it abundantly clear that earthquakes and tsunamis are crucial factors that must be included when considering the safety of nuclear power plants in Taiwan.
Taiwan is an isolated island-nation surrounded by water on all sides. In addition, it is located at the edge of the Eurasian plate where it meets the Philippine plate, a region where earthquakes can be felt on a regular basis. Any nuclear power station that is built on the coast of Taiwan is like a nuclear ticking time bomb that could go off at any time.
And unlike Japan, if there is a nuclear disaster in Taiwan, there will be no place to escape to and no place to hide.
Every person in Taiwan lives in the shadow of death, and the only way to guarantee the safety of our lives and homes and the lives and well-being of coming generations is a sustainable energy policy that disposes altogether of nuclear power.

In 1955, US general Benjamin Davis Jr, then-commander of the US’ 13th Air Force, drew a maritime demarcation line in the middle of the Taiwan Strait, known as the median line. Under pressure from the US, Taiwan and China entered into a tacit agreement not to cross the line. On July 9, 1999, then-president Lee Teng-hui (李登輝) described cross-strait relations as a “special state-to-state” relationship. In response, Beijing dispatched People’s Liberation Army (PLA) aircraft into the Taiwan Strait, crossing the median line for the first time since 1955. The PLA has begun to regularly traverse the line. On Sept. 18 and 19, it
Midday in Manhattan on Wednesday, September 16, was sunny and mild. Even with the pandemic’s “social distancing” it was a perfect day for “al fresco” dining with linen tablecloths and sidewalk potted palms outside one of New York City’s elegant restaurants. Two members of the press, outfitted with digital SLR cameras and voice recorders, were dispatched by The Associated Press to cover a rare outdoor diplomatic meeting on one of these New York streets. American diplomat Kelly Craft, Chief of the United States Mission to the United Nations, lunched in the open air with Taiwan’s ambassador-ranked representative in New York, James
Chinese Minister of Foreign Affairs Wang Yi (王毅) recently declared that aggression and expansionism have never been in the Chinese nation’s “genes.” It is almost astonishing that he managed to say it with a straight face. Aggression and expansionism obviously are not genetic traits, but they have defined Chinese President Xi Jinping’s (習近平) tenure. Xi, who in some ways has taken up the expansionist mantle of Mao Zedong (毛澤東), is attempting to implement a modern version of the tributary system that Chinese emperors used to establish authority over vassal states: submit to the emperor, and reap the benefits of peace and
Unlike its previous practice of disclosing the latest activities of the Chinese People’s Liberation Army (PLA) in a press release, the Ministry of National Defense has in the past few weeks followed the model of the Japanese Ministry of Defense. When carrying out surveillance and reconnaissance of the nation’s waters and airspace, it has posted real-time military activity updates on its Chinese-language Web site, explaining with text and graphs the responses and measures taken by the nation’s armed forces. The disclosed information on PLA activities show that the military is capable of maintaining regional security and safeguarding a free and open
