Tracking Deep Magma Migration Through Diffuse CO2 Degassing: Insights From Piton de la Fournaise Volcano (2013–2023)

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract Volcano monitoring requires identifying and distinguishing physico‐chemical processes at various depths within magma plumbing systems and their links to volcanic activity. Long‐term monitoring of deep magma reservoirs, extending down to tens of kilometers, is crucial even though signals from these depths are often altered or attenuated before ...

Crustal Magma Storage and Plumbing System Beneath the Tianchi and Wangtian'e Volcanoes, Changbaishan Intraplate Volcanic Field, China and North Korea

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract The Changbaishan volcanic field, which includes the Tianchi and Wangtian'e volcanoes in China and the Namphothe volcano in North Korea, is one of the most complex and hazardous volcanic regions on Earth due to its tectonic setting and explosive Holocene activity.

Gravimetric determination of the continental oceanic boundary of the Argentine continental margin (from 36°S to 50°S) [PDF]

, 2016
This paper presents the gravimetric analysis together with seismic data as an integral application in order to identify the continental?oceanic crust boundary (COB) of the Argentine continental margin from 36◦S to 50◦S in a continuous way.

Structure of the North‐Central Chile Subduction Zone From Local Earthquake Tomography

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract The fluid cycle in subduction zones prescribes large parts of its structure and seismogenic behavior. Background seismicity inside the downgoing slab is linked to fluid release from dehydration reactions, whereas fluid overpressure along the plate interface can alter interplate coupling, megathrust earthquakes, and the presence or absence of ...

Crustal velocity structure of the Apennines (Italy) from P-wave travel time tomography

Annals of Geophysics, 1996
In this paper we provide P-wave velocity images of the crust underneath the Apennines (Italy), focusing on the lower crustal structure and the Moho topography.

Autocorrelation‐Based Imaging of Crustal Discontinuities Including the Main Himalayan Thrust and Vp/Vs Ratio in the Jammu and Kashmir Himalaya

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract The Jammu and Kashmir Himalaya, located between the rupture zones of the 1905 Kangra and 2005 Kashmir earthquakes, represent a prominent “seismic gap” where understanding the subsurface structure is critical for seismic hazard assessment. This study presents new insights into the crustal structure of this region using teleseismic P‐wave coda ...

Influence of station topography and Moho depth on the mislocation vectors for the Kyrgyz Broadband Seismic Network (KNET) [PDF]

Geophysical Journal International, 2013
Deviations of slowness and backazimuth from theoretically calculated values, the so-called mislocation vectors, are measured for the Kyrgyz Broadband Seismic Network (KNET) in the Tien Shan region. 870 events have been analysed for arrivals of P and PKP waves from all azimuths.
