But scientists fear there could be more eruptions from the 5,466-foot volcano, Mount Eyjafjallajkull.      A university geophysicist said, "From what we've seen, it could erupt, pause for a few weeks, and then possibly erupt again. It could go on for months." As the no fly zone expanded yesterday, so did the chaos. The Icelandic volcano causing travel chaos across Europe could go on erupting for months, geologists have warned.      The National Air Traffic Control Service (Nats) extended restrictions on flights from British airports to 7 p.m. on Sunday, with the expectation of further extensions.      Ferry operators have reported record bookings. P&O took 6,000 foot passengers across the Channel onFriday compared to the 100 to 200 it would expect on a normal Friday in April.      Eurostar trains were fully booked until tomorrow, with 50,000 more passengers than normal since theairline disruption (中断) began on Thursday, including comedian John Cleese who arrived back in London lastnight after a most difficult overland journey from Switzerland.      The operator is charging passengers a minimum ＄223 for a single ticket from Paris to London over the next two days prompting criticisms of profiteering. A return ticket can normally be bought for as little as 69. Eurostar denied it was cashing in.      Some 4,000 British tourists have been stranded in South Africa.      The British Embassy in Athens said there were currently "many thousand" British holidaymakers trying toleave Greece after the holidays, in many cases anxious to get back in time for the start of the school term this week, with some of those desperate to return resorting to renting cars or embarking on long train journeys. 1.
