The cooling operation ended on 10 July 1973, and approximately 7.3 million cubic metres of seawater were pumped. This eruption was a special case where the method used to control the lava was suited to local conditions. Firstly, the initial eruption was only 1100 yards from the centre of town and harbour. Next, the flow of lava was slow and allowing time to plan and carry out control. Thirdly, sea water was available in its nearby harbour and lastly, it was easy to move pipes and pump equipment as the transport system by sea and road was good. (Richard & James, 1983) The entire operation cost a total of US$1,447,742 at the time.
