Quality assessment of daily GNSS coordinate time series from the SoftBank proprietary reference network

Earth, Planets and Space
In recent years, earth science disciplines have begun to rely heavily on geospatial data to determine crustal deformation associated with earthquakes and volcanic activity. Therefore, having adequately high-resolution data is essential. In this study, we

Initial colonization by bryophytes and ferns during primary succession on Nishinoshima, Japan

Nordic Journal of Botany, EarlyView.
Volcanic islands that have experienced complete vegetation loss following recent eruptions provide rare opportunities to observe the earliest stages of ecosystem recovery. Nishinoshima, an oceanic island located approximately 1000 km south of mainland Japan, underwent major volcanic activity between 2013 and 2020, eradicating all pre‐existing ...

Discrete radiation sources of the 2024 Noto Peninsula earthquake: linking teleseismic pulses and near-field observations

Earth, Planets and Space
Understanding the rupture process of large earthquakes is critical; however, standard rupture process inversions require stabilizing constraints, which can obscure which features are genuinely required by the data.

Prevalence of asymmetrical rupture in small earthquakes and its effect on the estimation of stress drop: a systematic investigation in inland Japan

Geoscience Letters, 2019
Stress drops of small earthquakes have been estimated under the assumption that the rupture propagates symmetrically within a circular fault. However, recent studies have observed directivity effects on seismic waves even for small earthquakes.

Nano-volcanic Eruption of Silver

Scientific Reports, 2016
AbstractSilver (Ag) is one of the seven metals of antiquity and an important engineering material in the electronic, medical, and chemical industries because of its unique noble and catalytic properties. Ag thin films are extensively used in modern electronics primarily because of their oxidation-resistance. Here we report a novel phenomenon of Ag nano-

Crisis Preparation, Capacity Building, and Community Resilience: Lessons From Maui

Nonprofit Management and Leadership, EarlyView.
ABSTRACT The 2023 Maui wildfires provide a unique context to explore the impact of nonprofit crisis networks taking a proactive role in community crisis response, leveraging resources, expertise, and networks. The Hawaiʻi Community Foundation (HCF) has been a key player in Maui's local response, providing critical support, mobilizing volunteers, and ...

Coseismic crustal seismic velocity changes associated with the 2024 MW 7.5 Noto earthquake, Japan

Earth, Planets and Space
The 2024 $$\hbox {M}_{\textrm{w}}$$ M w 7.5 Noto earthquake, Japan, was preceded by an intense seismic swarm thought to be driven by upward fluid migration.

Real‐Time Coseismic Slip Estimation via the GNSS Carrier Phase to Fault Slip Approach: A Case Study of the 2016 Kumamoto Earthquake

Geophysical Research Letters, 2019
We investigate the feasibility of Global Navigation Satellite System (GNSS)‐based deformation monitoring that detects coseismic fault slip directly from GNSS carrier phases without conventional positioning analysis.

Climatic Impact of Volcanic Eruptions [PDF]

The Scientific World JOURNAL, 2002
Volcanic eruptions have the potential to force global climate, provided they are explosive enough to emit at least 1–5 megaton of sulfur gases into the stratosphere. The sulfuric acid produced during oxidation of these gases will both absorb and reflect incoming solar radiation, thus warming the stratosphere and cooling the Earth’s surface.

Repeated Pleistocene Permafrost Episodes in the Western Pannonian Basin

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Concerning the study of past periglacial processes, the Pannonian Basin is a key area as it contains the southernmost frost polygons found in Central Europe. The presence or absence of permafrost is still, however, a matter of debate, and data on the timing of frost action are also scarce.
