X‐ray computed tomography study of terrestrial analog cores in preparation for Mars sample return

Meteoritics &Planetary Science, EarlyView.
Abstract Mars Sample Return (MSR) is expected to transform planetary science by providing unprecedented access to pristine Martian material. Initial characterization in the sample receiving facility (SRF) will rely on nondestructive techniques such as X‐ray computed tomography (XCT) to document the condition, distribution, and internal features of ...

Geochemical and Thermodinamic Modeling of Segara Anak Lake and the 2009 Eruption of Rinjani Volcano, Lombok, Indonesia

Indonesian Journal on Geoscience, 2014
DOI: 10.17014/ijog.v5i4.106Rinjani is the second highest volcano in Indonesia with an elevation of 3726 m above sea level. The steep and highest cone of Rinjani consists mainly of loose pyroclastic ejecta and contains a crater with a few solfataras.

Characteristics of the summit lakes of Ambae volcano and their potential for generating lahars [PDF]

Natural Hazards and Earth System Sciences, 2009
Volcanic eruptions through crater lakes often generate lahars, causing loss of life and property. On Ambae volcano, recent eruptive activities have rather tended to reduce the water volume in the crater lake (Lake Voui), in turn, reducing the chances for

A Youthful Titan Implied by Improved Impact Simulations

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract The small number of impact craters found on Titan suggests that its surface is relatively young. Previous work estimated its surface age to be between 200 and 1000 Myr. This estimate, however, is based on crater scaling laws for water and sand, which are not representative of the composition of Titan's icy surface.

Exploring Electrical Resistivity Tomography (ERT) to Detect Soil Pipes: Theoretical Modeling and Field Experiments

Land Degradation &Development, Volume 37, Issue 3, Page 1126-1142, 15 February 2026.
ABSTRACT Soil erosion research remains critical for sustainable development as it impacts soil health through different erosive processes. Recent studies on soil piping highlight advancements in detecting surface features (using UAV); however, detecting underground pipes still remains challenging.

Hazardous crater lakes studied

Eos, Transactions American Geophysical Union, 1993
Crater lakes usually sit on top of volcanic conduits and act as condensers of magmatic vapor. Studies of crater lakes can therefore provide information on both deep magmatic activity and variations in the degassing state of a shallow magmatic body. The Lake Nyos gas disaster of August 1986 and a similar event in August 1984 at Lake Monoun, both in ...

Coupled authigenic Mg silicate and carbonate precipitation in saline lakes of the Salar de Atacama, Northern Chile

The Depositional Record, Volume 12, Issue 1, February 2026.
Sediments, unlithified and lithified microbial mats in the Salar de Atacama, are formed by similar pathways involving coupled precipitation of authigenic Mg silicate and calcium carbonate. Differences in products reflect differences in the initial distribution of organic biomass.

Changes in crater lake chemistry after the 2021 eruption at Aso Volcano, Japan: insights from UAV-based hot water sampling

Journal of Asian Earth Sciences: X
Several volcanoes in Japan have summit craters filled with water, including Zao, Kusatsu-Shirane, Kirishima, and Aso volcanoes. Aso Volcano, located in central Kyushu, is an active caldera volcano with a crater lake whose water volume varies from nearly ...
