Tephrochronology (from tephra, Gk 'ashes') is a unique stratigraphic method for linking,
dating, and synchronizing geological, palaeoenvironmental, or archaeological sequences or …

Ideal for both undergraduate and graduate students in the fields of geography, forestry,
ecology, geographic information science, remote sensing, and photogrammetric …

The magma ocean concept was first conceived to explain the geology of the Moon, but
hemispherical or global oceans of silicate melt could be a widespread “lava world” phase of …

Mapping lithology and geological structures accurately remains a challenge in difficult
terrain or in active mining areas. We demonstrate that the integration of terrestrial and drone …

The latest generation of high-spatial-resolution satellites produces measurements of high-
temperature volcanic features at global scale, which are valuable to monitor volcanic activity …

Imaging spectrometry, simultaneous measurement of spectra and images in up to hundreds
of spectral channels or bands, is a proven technology for identifying and mapping minerals …

Abstract The topography of Mt. Etna, Italy, is subjected to continuous modifications
depending on intensity and magnitude of eruptions that frequently occur at the volcano …

Optical and laser remote sensing provide resources for monitoring volcanic activity and
surface hydrothermal alteration. In particular, multispectral and hyperspectral imaging can …

Accurate mapping of recent lava flows can provide significant insight into the development of
flow fields that may aid in predicting future flow behavior. The task is challenging, due to …

Volcanic thermal anomalies are monitored with an increased application of optical satellite
sensors to improve the ability to identify renewed volcanic activity. Hotspot detection …
