Triangulation scale error caused by the 1894 Shonai earthquake: a possible cause of erroneous interpretation of seismic potential along the Japan Trench

Earth, Planets and Space, 2018
Horizontal crustal strain in the Tohoku area during the twentieth century based on triangulation showed N–S extension and E–W contraction was not significant.

Development of OrSAEv Model Learning: Preliminary Study of Students’ Prepareness Facing Volcanic Eruption Disaster

Studies in Learning and Teaching, 2021
Geologically, Indonesia is a country prone to disasters, particularly volcanic eruptions. One of the steps that can be taken to minimize the impact of volcanic eruptions is through the education sector as foundation the knowledge, attitudes, and skills ...

Southern Annular Mode response to volcanic eruptions: implications for ice core proxies [PDF]

, 2011
Large tropical volcanic eruptions have been observed to have a significant influence on the large-scale circulation patterns of the Northern Hemisphere, through mechanisms related to the radiative effects of the sulfate aerosols resulting from the ...

A stress-controlled mechanism for the intensity of very large magnitude explosive eruptions [PDF]

, 2011
Large magnitude explosive eruptions are the result of the rapid and large-scale transport of silicic magma stored in the Earth's crust, but the mechanics of erupting teratonnes of silicic magma remain poorly understood.

Exchangeable lead (Pb) in lowland paddy soils of Sri Lanka as affected by the differences in agro‐climatic zones, soil orders, and water sources

PLANTS, PEOPLE, PLANET, EarlyView.
Lead (Pb) accumulation in the human body poses serious health risks. As rice is the staple food in Sri Lanka, with a high per capita intake (114 kg), there is a significant risk of Pb transfer through rice consumption. This study evaluated exchangeable Pb concentrations in soils and produced Pb distribution maps.

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.

Thermal vesiculation during volcanic eruptions [PDF]

Nature, 2015
Terrestrial volcanic eruptions are the consequence of magmas ascending to the surface of the Earth. This ascent is driven by buoyancy forces, which are enhanced by bubble nucleation and growth (vesiculation) that reduce the density of magma. The development of vesicularity also greatly reduces the 'strength' of magma, a material parameter controlling ...

Meteorological conditions leading to a catastrophic, rain‐induced landslide in Cameroon in October 2019

Quarterly Journal of the Royal Meteorological Society, EarlyView.
October 2019 was characterized by three main multiday wet spells in Bafoussam and Dschang. Our results indicated that wet spells were influenced by a vortex pair near the Gulf of Guinea, a strong Sahara Heat Low located anomalously far east and north, a northward shift of the intertropical discontinuity, an enhancement of the inland penetration of the ...

Stress field in northeastern Japan and its relationship with faults of recent earthquakes

Earth, Planets and Space
Inversion tectonics, in which old normal faults act as reverse faults in current stress fields, are frequently observed in northeastern Japan (Tohoku District); however, the conditions that control these fault activities remain unclear.

Seismic imaging of slab metamorphism and genesis of intermediate-depth intraslab earthquakes

Progress in Earth and Planetary Science, 2017
We review studies of intermediate-depth seismicity and seismic imaging of the interior of subducting slabs in relation to slab metamorphism and their implications for the genesis of intermediate-depth earthquakes.
