Potential for crustal deformation monitoring using a dense cell phone carrier Global Navigation Satellite System network

Earth, Planets and Space, 2022
Monitoring of crustal deformation provides essential information for seismology and volcanology. For such earth science fields and other purposes, various Global Navigation Satellite System (GNSS) networks have been constructed at the national and ...

Hydrological and Chemical Budgets of Okama Crater Lake in Active Zao Volcano, Japan

Hydrology, 2022
The Okama Crater Lake is located in the highly active Zao Volcano on the boundary of Miyagi and Yamagata Prefectures, Japan. At present, the lake stays relatively calm with neither bubbling, steaming nor gas smell at a pH of 3.2–3.4, though the lake did ...

Assessment of directional accuracy of GNSS-Acoustic measurement using a slackly moored buoy

Progress in Earth and Planetary Science, 2019
We assessed the positioning accuracy of GNSS-Acoustic (GNSS-A) measurement using a slackly moored buoy. A key feature of real-time buoy-based GNSS-A measurement is that positioning must be performed via single ranging from an arbitrary observation ...

Evaluation of the favorability of faults to slip: the case of the 2024 Noto Peninsula earthquake

Earth, Planets and Space
The 2024 Noto Peninsula earthquake (M 7.6) occurred at a depth of approximately 15 km in the eastern part of Noto Peninsula. The high dip angle faults (50–60°) in this area were formed by the extensional stress field during the formation of the Japan Sea.

The extension of the taxon cycle model to island plants: insights from the Canarian vascular flora

Biological Reviews, EarlyView.
ABSTRACT Taxon cycle models describe eco‐evolutionary patterns of lineage colonization, diversification, and decline across archipelagos, inferring an important role for competition amongst ecologically similar taxa in driving concurrent niche changes.

Resilience in a noisy urban system

Regional Science Policy &Practice, EarlyView., 2023
Abstract The ability of cities to recuperate from disturbances and return to their evolutionary pathways depends, first and foremost, on the type of damage that the shock created. But in addition, it depends on how information is transmitted in the urban system and on how noise filters distort the information that reaches economic agents.

Charge State Influence on Stability and Isomerism in Dehydrogenated PAHs: Insights from Anthracene, Acridine, and Phenazine

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
The ionization of anthracene, acridine, and phenazine has been explored, along with the removal of one and two hydrogen atoms, to provide valuable information for astrochemists and to understand the behavior of the resulting structures and their electronic reorganization. Abstract In this study, we systematically explored the stability and isomerism of

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

Deep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Shear wave splitting and seismic velocity structure in the focal area of the earthquake swarm and their relation with earthquake swarm activity in the Noto Peninsula, central Japan

Earth, Planets and Space
Seismic activity in the Noto region of Ishikawa Prefecture, central Japan, has increased since August 2020 and has continued as of August 2023. Stress changes due to subsurface sources and increases in fluid pressure have been discussed as the causes of ...

Precise aftershock distribution of the 2019 Yamagata-oki earthquake using newly developed simple anchored-buoy ocean bottom seismometers and land seismic stations

Earth, Planets and Space, 2022
An earthquake with a magnitude of 6.7 occurred in the Japan Sea off Yamagata on June 18, 2019. The mainshock had a source mechanism of reverse-fault type with a compression axis of WNW–ESE direction.
