• The initial value problem of the Hasegawa-Mima (HM) equation, whichdescribes the propagation of drift waves in a low beta magnetized plasma, isnumerically' studied. Solitons are formed from an initial sinusoidal wave. Fora wide range of initial conditions, the number of solitons and the recurrencetime aaee well with those obtained from the KdV eq. reduced from the HMeq. by Nozaki et at. As a result of nonlinear interactions among different solitons,their peak positions shift in the direction normal to the zeroth order convectivemotion in a regular but different fashion. When we start from a sinusoidal wave,the r>eaks of the senerated soliton train line ur>on a line at an anzle with resr>ectto the convective direction. Two-dimensional collisions of different solitons areexamined.
