The role of abnormal phases in nuclear matter on the basis of the well-known Lee-Wick theory is studied for the determination of the shock strength at the core bouncing of type II supernova. Relativistic equation for collapse beyond nuclear density with a still stronger magnetic field is developed to study the effect of appearance of the abnormal phases. This leads to the softening of the equation of state giving rise to strong shock. The magnetar thus formed can be a store-house of many high energy events including rapid gamma-ray bursts. A strong magnetic field beyond some critical value sometimes can exponentially accelerate certain reactions producing rapid bursts of energy. Some seismic events on the solidified crusts of magnetars can also be alluded for the short gamma-ray burst discovered in December 2004 at the site of SGR 1806-20.
