Open AccessMassive earthquake swarm driven by magmatic intrusion at the Bransfield Strait, Antarctica
An earthquake swarm affected the Bransfield Strait, Antarctica, a unique rift basin in transition from intra-arc rifting to ocean spreading. The swarm, counting ~85,000 volcano-tectonic earthquakes since Augus...

Open AccessThe Hindu Kush slab break-off as revealed by deep structure and crustal deformation
Break-off of part of the down-going plate during continental collision occurs due to tensile stresses built-up between the deep and shallow slab, for which buoyancy is increased because of continental-crust su...

Months-long thousand-kilometre-scale wobbling before great subduction earthquakes
Megathrust earthquakes are responsible for some of the most devastating natural disasters1. To better understand the physical mechanisms of earthquake generation, subduction zones worldwide are continuously monit...

Multi-GNSS satellite clock estimation constrained with oscillator noise model in the existence of data discontinuity
During the past years, real-time precise point positioning has been proven to be an efficient tool in the applications of navigation, precise orbit determination of LEO as well as earthquake and tsunami early ...

Open AccessBack to full interseismic plate locking decades after the giant 1960 Chile earthquake
Great megathrust earthquakes arise from the sudden release of energy accumulated during centuries of interseismic plate convergence. The moment deficit (energy available for future earthquakes) is commonly inf...

Ionospheric map** functions based on electron density fields
We develop an ionospheric map** function (MF) for the global navigation satellite system (GNSS) which is based on the electron density field derived from the international reference ionosphere (IRI). The sta...

Improving the modeling of the atmospheric delay in the data analysis of the Intensive VLBI sessions and the impact on the UT1 estimates
The very long baseline interferometry (VLBI) Intensive sessions are typically 1-h and single-baseline VLBI sessions, specifically designed to yield low-latency estimates of UT1-UTC. In this work, we investigat...

Open AccessTropospheric delay determination by Kalman filtering VLBI data
The troposphere is one of the most important error sources for space geodetic techniques relying on radio signals. Since it is not possible to model the wet part of the tropospheric delay with sufficient accur...
