Because of a volcanic eruption, what city was forced to turn over the 1908 Summer Olympics to London?

Our old pal Mt Vesuvius had a violent eruption in 1906 forcing Rome to give up the 1908 Olympics. Rome did not get a chance to host its first Olympic games until 1960. The 1908 London games actually lasted over 6 months making it the longest games in history. The London Games were also the first to have an opening ceremony and to award the gold, silver, and bronze medals.
