Mantle Transition Zone Topography in New Zealand From Teleseismic P $P$‐Wave Receiver Functions

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract The geology of New Zealand has been shaped by tectonic plate interactions driven by mantle convection over the past 60 million years, but the effects of these interactions on the transition to the lower mantle are not yet well understood. We analyze 10 years of teleseismic P $P$‐wave receiver functions using common conversion point stacking to

Earthquake Source Depth Determination Using Single Station Waveforms and Deep Learning

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract In areas with limited station coverage, earthquake depth constraints are much less accurate than their latitude and longitude. Traditional travel‐time‐based location methods struggle to constrain depths due to imperfect station distribution and the strong trade‐off between source depth and origin time.

Crustal structure below Popocat\'epetl Volcano (Mexico) from analysis of Rayleigh waves [PDF]

, 2007
An array of ten broadband stations was installed on the Popocat\'epetl volcano (Mexico) for five months between October 2002 and February 2003. 26 regional and teleseismic earthquakes were selected and filtered in the frequency time domain to extract the

Heat and Tectonics of the Canadian Cordillera From the Seismically Constrained Inversion of Gravity Data

Tectonics, Volume 45, Issue 2, February 2026.
Abstract An updated approach to seismically constrained modeling of gravity data reveals two broad, NW‐trending low‐density zones in the mantle lithosphere beneath the Canadian Cordillera. The low‐density zones coincide with a shallow lithosphere‐asthenosphere boundary (LAB), a shallow Curie‐point depth, and the location of Quaternary volcanoes.

Shear wave structure of a transect of the Los Angeles basin from multimode surface waves and H/V spectral ratio analysis [PDF]

, 2020
We use broad-band stations of the ‘Los Angeles Syncline Seismic Interferometry Experiment’ (LASSIE) to perform a joint inversion of the Horizontal to Vertical spectral ratios (H/V) and multimode dispersion curves (phase and group velocity) for both ...

U and Th content in the Central Apennines continental crust: a contribution to the determination of the geo-neutrinos flux at LNGS

, 2011
The regional contribution to the geo-neutrino signal at Gran Sasso National Laboratory (LNGS) was determined based on a detailed geological, geochemical and geophysical study of the region.

The maternal role of community‐dwelling older women: A qualitative study

Family Relations, Volume 75, Issue 1, Page 197-212, February 2026.
ABSTRACT Objective To explore the maternal role through the subjective experiences of community‐dwelling older mothers. Background Participation in meaningful life roles is essential for older adults' health. Motherhood, a meaningful life role of many women, includes various activities, but research has not focused on this role at older age. This study

Crustal structure beneath the Trondelag Platform and adjacent areas of the Mid-Norwegian margin, as derived from wide-angle seismic and potential field data [PDF]

, 2010
The outer mid-Norwegian margin is characterized by strong breakup magmatism and has been extensively surveyed. The crustal structure of the inner continental shelf, however, is less studied, and its relation to the onshore geology, Caledonian structuring,

A novel mechanism of auxin habituation: upregulation of auxin receptor TRANSPORT INHIBITOR RESPONSE 1 allows cell proliferation independent of external auxin

New Phytologist, Volume 249, Issue 3, Page 1268-1282, February 2026.
Summary Exogenously applied auxins are essential for establishing cell lines in tissue cultures and maintaining their proliferation. Cell lines may develop the ability to proliferate even in media lacking auxin, they may become auxin‐habituated. This study investigated the mechanisms underlying this process.

Seismological Evidence of Multiple Crustal Magma Reservoirs Beneath Mt. Wrangell in Southcentral Alaska

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Recent studies have challenged the classical view of magma chambers as ephemeral, melt‐rich bodies confined to shallow depths beneath arc volcanoes at subduction zones. Instead, increasing evidence supports the existence of long‐lived, vertically extensive magmatic systems with persistent partial melts within the crust. Nevertheless, the depth
