The safety factor within a tokamak plasma has been measured during a major disruption. During the disruption, the central safety factor jumps from less than unity to above unity, while the total current is unchanged. This implies that total reconnection has occurred. This observation is in contrast to the absence of total reconnection observed during a sawtooth oscillation in the same device.
