Rates and Causes of Tailings Dam Failures

Estimation of Europe tailings number by type.

Type	Number GRIDA	Percentage	Estimated number in Europe
Upstream	44	41.3	452
Centerline	5	7.4	81
Downstream	33	25.5	279
Single stage	1	7.2	79
Other	13	18.6	203

Percentage refers to because GRIDA tailings dams from Europe are underreported, the percentages per type correspond to the world database are used. Estimated number in Europe refers to estimates computed by extrapolating data from the European Commission [29] and Zibret et al. [45].
