Regional-scale input of dispersed and discrete volcanic ash to the Izu-Bonin and Mariana subduction zones [PDF]

open access: yes, 2014
We have geochemically and statistically characterized bulk marine sediment and ash layers at Ocean Drilling Program Site 1149 (Izu-Bonin Arc) and Deep Sea Drilling Project Site 52 (Mariana Arc), and have quantified that multiple dispersed ash sources ...

Improving Global Radial Anisotropy Tomography: The Importance of Simultaneously Inverting for Crustal and Mantle Structure [PDF]

open access: yes, 2017
Observed seismic anisotropy gives the most direct information on mantle flow, but it is challenging to image it robustly at global scales. Difficulties in separating crustal from mantle structures in particular can have a strong influence on the imaging.

Reappraisal of the Arc-Arc Collision in Taiwan

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2009
Al though it is evident that Taiwan has been formed by the collision of the west-facing Luzon arc with the Eurasian continental mar gin, there're main a lot of enigmas in this collision. The major ones are: (1) a trans form fault presently connecting the

Tsunami hazard analysis for Chinese coast from potential earthquakes in the western North Pacific

open access: yesGeomatics, Natural Hazards & Risk, 2020
China is a Pacific coastal country, adjacent to the Circum-Pacific seismic belt. The tsunami from the western North Pacific is very dangerous to China because of the short distance.

Tectono-magmatic evolution of the Philippine Sea Plate: A review

open access: yesGeosystems and Geoenvironment, 2022
The West Pacific Margin incorporates 75% of global marginal basins/back-arc basins. These basins and their adjacent trenches and island arcs constitute a huge trench-arc-basin system created by the interactions among three tectonic plates (the Pacific ...

Segmentation of the Izu-Bonin and Mariana slabs based on the analysis of the Benioff seismicity distribution and regional tomography results [PDF]

open access: yes, 2013
We present a new model of P and S velocity anomalies in the mantle down to a depth of 1300 km beneath the Izu-Bonin and Mariana (IBM) arcs. This model is derived based on tomographic inversion of global travel time data from the revised ISC catalogue ...

Tsunami Risk Change Analysis for Qidong County of China Based on Land Use Classification

open access: yesJournal of Marine Science and Engineering, 2023
Tsunamis can cause high numbers of casualties, as well as direct and indirect economic losses to coastal regions. The huge destructiveness of tsunamis requires us to study tsunami risk and its temporal change. We adopt the tsunami scenarios of the Ryukyu

Double seismic zones and stresses of intermediate depth earthquakes [PDF]

open access: yes, 1981
Data from Japanese local seismograph networks suggest that the stresses in double seismic zones are in-plate compression for the upper zone and in-plate tension for the lower zone; the stresses do not necessarily appear to be down-dip.

Rupture Process of Subduction-Zone Earthquakes [PDF]

open access: yes, 1986
This review is primarily concerned with the rupture process of large subduction-zone earthquakes determined by various seismological methods, and with its interpretation in terms of an asperity model.

Tsunami Folklore and Possible Tsunami Source on the Eastern Coast of Taiwan

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2013
Folklore tells of a large sea wave that struck an area of Chenggong on the eastern coast of Taiwan. This event is estimated to have occurred in the middle of the 19th century based on an oral history of the area.
