By Simon Falush LONDON, Jan 10 (Reuters) - Gasoline cracks bounced to their highest in a month on Thursday, supported by demand from the United States, traders said. A number of refinery maintenance and pipeline problems in the United States have left stocks on the east coast relatively low, which has led to cargoes being brought over from Europe. "Continued misshaps have kept Padd1 stocks below average levels, accordingly we are still seeing north-west European stocks being booked for transatlantic shipments, which means gasoline is finding some support," a trader said. Weekly gasoline stocks independently held in Amsterdam-Rotterdam-Antwerp trading hub rose 8.6 percent to 754,000 tonnes, independent analyst Pieter Kulsen said. European oil product stocks fell month-on-month in December, while crude stocks gained on the year, data from industry monitor Euroilstock showed. Gasoline stockpiles fell 0.1 percent on the month and were 4.4 percent lower than last year at 105.49 million barrels. Naphtha stocks fell 10.7 percent from the previous year to 29.92 million barrels the data showed.
