Location and Mechanism of Very Long Period Tremor During the 2008 Eruption of Okmok Volcano from Interstation Arrival Times [PDF]

, 2010
We describe continuous, very long period (VLP) tremor that occurred during the 2008 eruption of Okmok Volcano, Alaska. Due to its low frequency content in band from the 0.2–0.4 Hz, the wave field of the VLP tremor is relatively free of path effects. From

Migration of Multimodal Deep Crustal Earthquake Swarm Beneath the Abu Volcano Group, Japan

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Earthquakes in the lower crust, where high pressures and temperatures favor ductile deformation, are rare but occasionally occur beneath active volcanic centers, providing insights into deep magmatic processes. We analyze a deep crustal earthquake swarm (February–August 2025) of over 5,000 events beneath the Abu Volcano Group, Japan.

MSC‐Derived Exosomal lnc‐AGT‐3: A Novel Anti‐Angiogenic Target in Age‐Related Macular Degeneration Through p53 Signaling Pathway

Aging Cell, Volume 25, Issue 2, February 2026.
MSC‐derived exosomes deliver lnc‐AGT‐3 to vascular endothelial cells, where it binds hnRNP K in the nucleus. This interaction inhibits p53 ubiquitination, enhancing p53 stabilization and transcriptional activation of anti‐angiogenic targets TSP1. Consequently, p53‐mediated signaling is potentiated, effectively suppressing choroidal neovascularization ...

Salt shell fallout during the ash eruption at the Nakadake crater, Aso volcano, Japan: evidence of an underground hydrothermal system surrounding the erupting vent

Earth, Planets and Space, 2018
A hot and acid crater lake is located in the Nakadake crater, Aso volcano, Japan. The volume of water in the lake decreases with increasing activity, drying out prior to the magmatic eruptions. Salt-rich materials of various shapes were observed, falling

Campi Flegrei volcanic surveillance by thermal IR continuous monitoring [PDF]

, 2012
Solfatara and Pisciarelli areas are the most impressive example of hydrothermal activity at Campi Flegrei caldera (Southern Italy). In these areas INGV-Osservatorio Vesuviano has been handling since 2004 a surveillance network for continuous, long-term ...

Pan‐cancer multi‐omics reveals DCAF7 as an immune‐modulating prognostic driver and Wnt/β‐catenin activator in hepatocellular carcinoma

Clinical and Translational Medicine, Volume 16, Issue 1, January 2026.
DCAF7 is up‐regulated in various tumours and correlates with poor prognosis, particularly in LIHC. High DCAF7 expression is linked to CD4+ T cell infiltration, up‐regulation of immune checkpoint genes and increased tumour mutational burden, suggesting a role in tumour immune escape.

Sliding layer estimation of shallow landslides on Aso volcanic mountains in Japan based on tephra layer-physical properties of soil

Geoenvironmental Disasters, 2020
Shallow landslides occur frequently on the Aso volcanic mountains. The soil materials on the Aso volcanic mountains consist of tephra layers formed by volcanic activities. This study is aimed to specify the physical properties of soil that correlate with

Spatial Interactions Govern Tectonic Tremor Activities in the Nankai Trough: A Statistical Approach for Spatiotemporal Pattern Modeling and Anomaly Detection

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract Establishing a quantitative framework to evaluate the spatiotemporal patterns of slow earthquakes and to detect their anomalous activities is essential for understanding diverse slip behaviors on plate boundaries and seismic hazard assessment. In this study, we focus on deep tectonic tremors, which are one manifestation of slow earthquakes and

Migration of Very Long Period Seismicity at Aso Volcano, Japan, Associated With the 2016 Kumamoto Earthquake

Geophysical Research Letters, 2019
Earthquakes are known to precede volcanic activity, including long‐period or very long period (VLP) volcanic seismicity. However, the relationships among earthquakes, VLP seismicity, and volcanic eruptions are not well understood.

Grade of weathering and fertility of volcanic ash soils of Aso volcano [PDF]

Soil Science and Plant Nutrition, 1966
Abstract Texture is one of the major criterions in soil classification, probably because it has a decisive influence on soil properties. This is particularly true for volcanic ash soils. Most ashes are largely composed of sand and silt particles with little clay (11, 15). The ash weathers very rapidly (1), and clay site particles less than 2 microns in
