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 ...

Ice core evidence for a second volcanic eruption around 1809 in the Northern Hemisphere [PDF]

, 2006
A volcanic signal observed in ice cores from both polar regions six years prior to Tambora is attributed to an unknown tropical eruption in 1809. Recovery of dacitic tephra from the 1809 horizon in a Yukon ice core (Eclipse) that is chemically distinct ...

Heterogeneous rheology of Japan subduction zone revealed by postseismic deformation of the 2011 Tohoku-oki earthquake

Progress in Earth and Planetary Science, 2023
The 2011 Tohoku-oki earthquake produced the most well-recorded postseismic deformation of any megathrust earthquake in the world. Over the last decade, researchers have used a dense and widespread geodetic network of more than 1300 Global Navigation ...

Volcanic studies by members of the Royal Society of London 1665 - 1780 [PDF]

, 1971
Late seventeenth century ideas about volcanic activity were largely derived from classical sources. The Philosophical Transactions of the Royal Society of London provided a vehicle for publication of information about volcanoes where many ancient notions

Modeling the distribution of the volcanic aerosol cloud from the 1783–1784 Laki eruption [PDF]

, 2006
We conducted simulations of the atmospheric transformation and transport of the emissions of the 1783–1784 Laki basaltic flood lava eruption (64.10°N, 17.15°W) using the NASA Goddard Institute for Space Studies modelE climate model coupled to a sulfur ...

Quasi-real-time earthquake relocation and monitoring in the northeastern Noto Peninsula

Earth, Planets and Space
The seismicity rate markedly increased in the northeastern Noto Peninsula of Ishikawa Prefecture around the end of 2020, with an Mw6.2 event on 5 May, 2023, followed by many aftershocks.

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.

High-latitude eruptions cast shadow over the African monsoon and the flow of the Nile [PDF]

, 2006
Nile River records indicate very low flow following the 1783–1784 Laki volcanic eruption, as well as after other high-latitude volcanic eruptions. As shown by climate model simulations of the Laki eruption, significant cooling (−1° to −3°C) of the ...

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
