Holocene shield volcanoes in Iceland
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)Holocene shield volcanoes (lava shields) are common in Iceland, but they are restricted in space and time. As regards space, most of the shield volcanoes in Iceland occur within two bands in the West and North Volcanic ... -
How stress transfer between volcanic and seismic zones affects volcanic and earthquake
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)Oceanic transform faults and ridge segments form a network where mechanical interaction is to be expected. In particular, dike emplacement in ridge segments is likely to affect earthquake activity in the adjacent transform ... -
