[4] b) Account for the different nature of volcanic eruptions shown in Fig. 1. [6] c) Explain how you would draw up a hazard map of an earthquake-prone region, identifying the areas of high and low risks. [2] The Globalisation of Economic Activity 2 Fig. 2 depicts a process in the developed countries. a) Briefly describe what Fig. 2 is trying to depict.
