Puerto Rico is a fairly large (top 100 largest) island with international airports. It is larger than many other islands that have observatories. Areceibo already WAS a world class telescope and was closer to an international airport than many other observatories. The only valid point you've made is about hurricanes and earthquakes. However I haven't seen any discussion as to how those effect contruction costs at that site vs others.
