Hekla
Hekla last erupted in 2000, but its most famous eruption was in 1845-1846.
"Mt. Hekla (‘mantle', probably from the mists usually shrouding its summit), the best-known, though not the largest volcano in Iceland, is a long mountain with several craters, the chief of which are the great S.W. crater (4629 ft.; 299 ft. deep) and the smaller, but higher N.E. crater (4747 ft.; 417 ft. deep), both filled with snow. History records eighteen great eruptions from 1104 down to the present day, that is 2-3 in each century, at very various intervals. The last occurred in 1845–6".--Baedeker 1912.
