Alluvial fan response to Alpine Fault earthquakes on the Westland piedmont, Whataroa, Aotearoa‐New Zealand Open
We examined the stratigraphy of alluvial fans formed at the steep range front of the Southern Alps at Te Taho, on the north bank of the Whataroa River in central West Coast, South Island, New Zealand. The range front coincides with the Alp…

Volcano-tectonic interactions at the southern margin of the Okataina Volcanic Centre, Taupō Volcanic Zone, New Zealand Open
The c. 15 km-long Ngapouri-Rotomahana Fault (NRF) is a major splay of the Paeroa Fault at the eastern margin of the modern Taupō Rift, the active tectonic structure embedded within the Taupō Volcanic Zone of North Island, New Zealand. The …

Glacial geomorphology of the central and southern Chilotan Archipelago (42.2°S–43.5°S), northwestern Patagonia Open
We present a geomorphic map of the glacial landforms associated with the Golfo Corcovado ice lobe in northwestern Patagonia. Built upon prior studies, our map elaborates on the central and southern sectors of Isla Grande de Chiloé and neig…

Fault ruptures triggered by large rhyolitic eruptions at the boundary between tectonic and magmatic rift segments: The Manawahe Fault, Taupō Rift, New Zealand Open
The Manawahe Fault is located at the boundary between the tectonic Whakatane and the magmatic Okataina segments of the Taupo ̄ Rift. We investigate prehistoric ground surface fault ruptures and their timing in asso- ciation with volcanic er…

A century of ongoing silicic volcanism at Cordón Caulle, Chile: New constraints on the magmatic system involved in the 1921–1922, 1960 and 2011–2012 eruptions Open
Cordón Caulle in southern Chile has produced three dacitic to rhyolitic fissure eruptions over the past century (in 1921–1922, 1960 and 2011–2012), and thereby provides an ideal opportunity to examine the architecture of its underlying sil…

EVALUATING THE RADIOCARBON RESERVOIR EFFECT IN LAKE KUTUBU, PAPUA NEW GUINEA – CORRIGENDUM Open
We examined the radiocarbon (14C) reservoir effect in Lake Kutubu using tephrochronology and terrestrial plant material to deliver a precise age-depth profile and sedimentation rates for this lake. Based on the presence of two tephra horiz…

Halogen (Cl, F) release during explosive, effusive, and intrusive phases of the 2011 rhyolitic eruption at Cordón Caulle volcano (Chile) Open
We investigate sulphur, chlorine and fluorine release during explosive, effusive and intrusive phases of the 2011 Cordón Caulle eruption, with a focus on halogen devolatilization. Petrological analysis shows halogen release to have been pr…
