Geochemical and petrographic characterizations were carried out on five episodic effusive eruptions from Batur Volcano on the Island of Bali, Indonesia, and revealed that these lavas are basaltic to andesitic in composition. Various micro-textures we

Anisotropy of magnetic susceptibility (AMS) analyses have been used widely in many applications that include studying lava flows. In this paper, we introduce an auxiliary parameter, i.e., preferred pore orientation, on the use of AMS for lava flow st

The non-uniqueness in the solution of gravity inversion poses a major problem in the interpretation of gravity data. To overcome this ambiguity, “a priori” information is introduced by minimizing a functional that describes the geometrical or phy

The Little Ice Age (LIA) describes cold conditions that lasted for centuries associated with the expansion of glaciers that could be initiated by a large volcanic eruption. The 1257 eruption of the Samalas volcano caused climatic impacts worldwide an
