Figure 7: The probability of volcanic disruption of the proposed repository, estimated using method 2, is bounded by the two curves, calculated using a = 8 km², t = 10,000yr. Open triangles - data set 2, including volcanoes formed less than 2 Ma and l_t = 10v/my; solid triangles - data set 1, including volcanoes less than 5 Ma and  l_t = 5 v/my.
