Spatial approaches, based on the deformation measurement of volcanic domes and crater
rims, is key in evaluating the activity of a volcano, such as Merapi Volcano, where …

The 1257 CE eruption of Samalas volcano, Indonesia, buried the entire island of Lombok
beneath various thicknesses of pyroclastic material during this Volcanic Explosivity Index …

Volcanic gullies develop U-shape cross-profiles due to the lahars that shape them after
eruptive events. Over time, the processes of sediment-transfer change and the erosion of …

Cotopaxi is an active volcano in Ecuador, whose eruptions are characterized by producing
destructive primary lahars which represent a major risk for the country. The hazard …

Rainfall-triggered volcanic debris flows (VDFs), or lahars, frequently occur during and/or
immediately after eruptions, often because of decreases in the infiltration capacity resulting …

As climate change creeps into the 21st century, the intensity of debris flows due to heavy
and concentrated rainfall has increased in mountainous regions of Japan and East Asia …

Internal temperature variations of pyroclastic flows and their deposits are arguably the most
challenging data to acquire. As a preliminary study of the temperature variation inside …

The first chapter is an introduction to the book. It explains what is meant by pointcloud
through the manuscript as well as how the technology has emerged through the field of …

Volcanic eruptions in Indonesia and other parts of the world have had many impacts, both
physical and social. However, only limited studies combine the investigation of physical and …
