BANGKOK -- Japan's Nikkei stock index nose-dived nearly 11% Tuesday as the earthquake-shattered country faced an unfolding nuclear crisis after a radiation leak was detected at a crippled power plant and residents were warned to stay indoors. Panic-selling sent shares lower across the globe.
The benchmark Nikkei 225 stock average sank a staggering 10.6% -- more than 1,000 points -- to close at 8,605.15 after hitting a midday low of 8,227.63 points, more than 14% down. The broader Topix, meanwhile, lost 8%. Oil prices fell below $100 a barrel, and Asian shares tanked amid fears that Japan's nuclear emergency would worsen.
The chill was felt in Europe, where shares were sharply lower in early trading. Britain's FTSE 100 lost 1.4% to 5,692.31, Germany's DAX was 2.6% down to 6,692.18 and France's CAC-40 sagged 1.8% to 3,803.27. Wall Street was bracing for a setback, with
Dow Jones Industrial Average
futures down 1.4% to 11,763 and
futures down 1.6% to 1,270.30.
In Japan, the Nikkei's losses followed a 6% tumble Monday -- the first trading day since a devastating earthquake and tsunami struck the northeastern coast, washing away towns and likely killing more than 10,000 people. Losses on Monday and Tuesday have sent the Nikkei spiraling downward 20% since the beginning of the year.
Other Asian markets plunged as large Japanese investors such as insurance companies and hedge funds pulled money from overseas, according to Tom Kaan, head of equity sales at Louis Capital Markets in Hong Kong.
Investors felt the biggest shock waves when Japan's prime minister announced that radioactive material had leaked from the Fukushima Dai-ichi nuclear plant in Fukushima province and that more leaks were possible. People living within 19 miles (30 kilometers) of the complex were told to stay indoors.
"There is also fear of contamination. We've never had three nuclear power plants blowing up one after the other," Kaan said. "When you have a situation like that, everyone takes to the extreme of being conservative. How far will it affect the air that we breath and how far will the contamination go? Is it going to reach Korea or China? That's anyone's guess."
Kaan said the Middle East crisis was still far from over and had the potential to further damage markets, oil prices, and the global economic recovery -- especially if the political turmoil and violence that has hit countries like Egypt and Libya spreads to oil powerhouse Saudi Arabia.
The stock selloff in Tokyo hit nearly every business sector, with electric companies under intense pressure again.
Tokyo Electric Power
, which operates the crippled nuclear plant, crashed 24.7%.

Even the rare stocks that did well Monday -- industrial and materials companies, which gained due to expectations that they would benefit when Japan rebuilds -- tumbled Tuesday.
Elsewhere in Asia, South Korea's Kospi lost 2.4% to 1,923.92 and Australia's S&P/ASX 200 fell 2.1% to 4,528.70. Hong Kong's Hang Seng index dropped 2.9% to 22,678.25.
In mainland China, the Shanghai Composite Index fell 1.4% to 2896.26, and the Shenzhen Composite Index of China's second, smaller exchange lost 1.3% to 1,293.61.
China's transportation sectors was hit particularly hard due to the uncertainly facing Chinese exports to Japan. Shares of
China Cosco Holdings
, a shipping and transport company, fell 3.7%.
"This will impact transportation of China's exports to Japan," said Peng Yunliang, a Shanghai-based analyst. "Everything is down because the market is worried about nuclear radiation. The market is worried that it may impact other regions, such as the Asia-Pacific region."
On Wall Street Monday, concerns over the economic impact of the earthquake and tsunami in Japan led to a broad selloff. The Dow lost 51.24, or 0.4%, to 11,993.16.
The broader S&P index fell 7.89 points, or 0.6%, to 1,296.39. Nine out of the 10 sectors that make up the Standard and Poor's 500 index lost ground. Utilities companies fell 1.4%, the most of any group.

The dollar was worth 81.55 Japanese yen Tuesday, down from 81.88 yen late Friday. A major natural disaster like an earthquake can bolster the yen because investors expect the Japanese public and insurance companies to buy back their home currency in order to fund the country's reconstruction, increasing demand for the yen.
The euro fell to $1.3934 from $1.3995.
