* FTSE down 2.2, investors flee risky equities
* Uranium explorers retreat on Japan's nuclear concerns
* Miners seen benefitting in aftermath
LONDON, March 15 (Reuters) - Around 32 billion pounds ($52 billion) was knocked off the value of London's blue-chip index on Tuesday, as the cost of Japan's devastating earthquake and tsunami saw investors flee riskier equity and commodity assets.
By 1147 GMT, the FTSE 100 <
> index was down 125.5 points, or 2.2 percent, at 5,649.74 having closed 0.9 percent lower on Monday. The index is down almost 6 percent in March."The FTSE is now trading 8 percent off its February highs and with the near term momentum gaining towards the downside," Joshua Raymond, Market Strategist at City Index, said.
"Traders could be waiting for the UK index to hit the 5,500 level before being enticed back into the market."
The previous session's relatively sedate reaction to the disaster in Japan was replaced by panic after Japan's Nikkei <
> overnight dropped 10.6 percent, as the cost of the devastation and concern over the ongoing nuclear crisis in the country mounted. [ ]The FTSE volatility index <.VFTSE>, which measures investor appetite for risk, was up over 15 percent, although volumes on the FTSE 100 were lighter than its European peers.
London's blue chips traded at just 66 percent it average 90-day volume compared to 140 percent on Germany's Dax <.GDAX>, with many putting this down to the start of the horse racing festival at Cheltenham.
Miners <.FTNMX1770> and Integrated oils <.FTNMX0530> were the top fallers, while traders said banks <.FTNMX8350> were trimming debt holdings to cover losses from a sharp slide in equities.
London-listed uranium explorers such as Berkeley Resources <BKY.L> and Kalahari Minerals <KAH.L> fell up to 25 percent on concerns over the future of the global nuclear power build programme amid fears of a major radiation leak from the nuclear complex in Fukushima following Japan's massive earthquake.
MINER HOPES
Traders, however, said longer-term the mining sector should see upside given their lacklustre start to the year and the need for Japan to rebuild. "Through the short-term volatility in the miners we expect them to move onto the upside (with today's sell off they are all down between 5-7 percent on the year)," Atif Latif, director of trading at Guardian Stockbrokers, said.
"Once the full impact (of the earthquake) becomes known we expect there to be strong demand for base metals and steel," he said, adding he also expects a flight to quality bid into utilities, historically a safe haven sector.
Among individual fallers impacted by the disaster in Japan was Luxury goods firm Burberry <BRBY.L>, down 4.3 percent, as investors sold stock on concerns over Japanese demand for its goods. Nomura analysts said the firm's licensing agreements in Japan in total generated around 17 percent of Group EBIT.[
]ARM Holdings <ARM.L> lost 3.2 percent as the chip designer suffered from disruption to production as a result of the massive quake in Japan.
UK retailers were the only stocks on London's blue chip index with upside momentum. Next <NXT.L> rose 1.8 percent helped, bullish broker comment, lower cotton prices and results from mid cap department stores group Debenhams <DEB.L>, ahead 4.1 percent.
U.S. stock index futures pointed to sharp drops on Wall Street on Tuesday, with investors focused on the crisis in Japan, but with one eye on U.S. housing market data and, more importantly, the FOMC rate decision due at 1815 GMT, after the London market close.
