Complex Shallow Unilateral Rupture of the 2025 Mw 7.0 Hubbard Glacier Earthquake Terminated by a Restraining Bend on the Connector Fault

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Despite decades of study, the detailed geometry of the Connector fault at the Alaska–Canada border remains poorly constrained. We investigate the rupture complexity and directivity of the 6 December 2025, Mw 7.0 Hubbard Glacier earthquake using hypocenter relocations, moment tensor inversions of the mainshock and aftershocks, and finite‐fault ...

A comparison of Bjerhammar's methods and collocation in physical geodesy

, 1978
In 1963 A. Bjerhammar solved the geodetic boundary value problem by applying Poisson's integral equation for a finite set of observed free-air gravity anomalies. Due to the relation between the number of observations (m) and the number of chosen unknowns

Sulfur Exposure for Airplane Passengers From Stratospheric Aerosol Injection

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Injection of sulfur dioxide to create a stratospheric sulfate aerosol cloud is the most studied method of climate intervention. It has been suggested that airplanes be used at high latitudes to create such a cloud at lower altitudes. Commercial airplanes routinely fly at altitudes of 11 km in the Arctic, and therefore passengers could be ...

The altimetry-gravimetry problem using orthonormal base functions

, 1986
This dissertation was undertaken in view of finding a numerical solution on a spherical earth of a mixed boundary value problem, the one of altimetry-gravimetry which is defined from gravity anomalies determined by gravimeter measurements mostly on ...

Discrete Physical Geodesy

, 1987
Discrete gravity information on the surface of the earth (and in space) is used for solutions of the free boundary value problem in physical geodesy. The primary tool for these solutions is a harmonic embedding with the use of a mathematical sphere. (For
