Cyclone Yasi started on the 29th of February as a tropical low north of Fiji
Cyclone names are chosen alphabetically. For example, if there is a cyclone name starting with A, and another cyclone follows, then that cyclone name will have to start with B. Also, the genders alternate with each name. This means that if one cyclone has a boy name starting with H, then the next cyclone must have a girl name starting with I.
The Gladstone cyclone of 1949 did not have a name. The naming of cyclones in the Australia region did not start until the 1960s.
As with all cyclones, Cyclone Yasi was generated from a low pressure system out at sea some days earlier. The sea temperatures and weather conditions were simply right for a cyclone to be generated from the tropical low.
The name of the cyclone that Vanuatu was Pam.
Weather phenomena are powerful things, and humanity is still far away from any realistic and reliable weather control. So no, cyclone Pam, or any other cyclone, could not be prevented. What is POSSIBLE though, is to have warning systems, evacuation plans and shelters, to prevent and reduce the risk to humans as far as possible.
Cyclone Tracy started as a tropical storm out in the Arafura Sea.
