Carbonate precipitation is controlled by fluid composition and flow, temperature, and the presence of mafic intrusions

Magnesite and dolomite formed at high Mg/Ca ratios and zones of channelized flow in serpentinized peridotites at the Atlantis Massif

CO₂ capture is limited in the shallower crust, concentrated around Lost City, but may be more extended in deeper circulation

Hydrological and tectonic gravitational signals in the northeastern Tibetan Plateau(NETP) are identified from multi-source data

Obvious positive gravitational signals appeared in NETP suggest material accumulation in this area

Uplift rates of the Moho and Earth's surface and the crustal thickness changes in NETP are estimated

Multi-anvil press experiments in the system MgSiO₃-SiO₂ at 24 GPa located the eutectic at 53 mol% SiO₂ and 2750 K

We build a thermodynamic model for MgO-SiO₂ based on the data and other constraints that allows extrapolation to the core-mantle boundary

Based on melting curves of MgO and SiO₂ and their liquid interaction parameter, the model predicts eutectic temperatures and compositions

A practical approach is developed to integrate Sentinel-1 InSAR and GNSS time-series over the entire San Andreas fault system

The product is used to estimate fault creep and three components of horizontal crustal strain rate which shows notable off-fault portion

Challenges remain in seperating tectonic and hydrologic sources and whether hydrologic strain will increase seismic hazards

A method was developed to determine the downhole mineral fractions of drill cores from continuous X-ray CT images

Quartz–magnesite–dolomite fractions were estimated from X-ray CT images of listvenite cores from ICDP Oman Drilling Project Hole BT1B

Results indicate limited material transfer during carbonation and hydration of the Samail ophiolite, except for Ca, CO₂, and H₂O

We compile diverse observations from geochronology, geochemistry, volcanology for the Deccan Traps to constrain magmatic architecture

These different datasets consistently suggest large, frequent eruptions for Deccan Traps (and potentially other CFBs)

Constraints from Deccan eruptive tempo, geophysics, and geochemistry are inconsistent with the large crustal magma reservoir model

Dilatancy strengthening leads to an increase in toughness of expanding shear cracks, which grows with increasing rupture speed

Crack propagation can be limited by the rate of fluid recharge far behind the crack tip

Dilatancy effect with reasonable parameter values is consistent with the dynamics of slow slip in subduction zones

We demonstrate the feasibility and potential of Distributed Acoustic Sensing (DAS) in alpine volcano-glacial environments

The DAS experiment at Mount Meager reveals unexpected volcanic tremor and volcanic earthquake swarms related to geothermal fluids

Mount Meager is significantly more active than previously estimated on the basis of conventional seismic instruments in the area

Coherent tremor signals are detected and located separately in relatively high-frequency (1.25-6.5 Hz) and low-frequency (0.5-1.25 Hz) bands

LF signals seem to consistently lag contemporaneous HF signals by ∼500 m relative to the propagating fronts of rapid tremor migrations

Persistent offsets suggest that LF signals may have a source distinct from just the temporal overlapping of typical higher-frequency LFEs

Strong seasonal variations in seismic velocity are observed in Sichuan, China from ambient noise interferometry

The seasonality varies in strength, amplitude, phase, periods, and location

The cause of the seasonality is likely the effects of elastic loading from the precipitation

The “neighborhood algorithm” provides a robust methodology for testing layered anisotropy in the Earth's inner core

There is no significant change observed in the strength of anisotropy with depth in the inner core

The innermost inner core is defined as a gradual change in the slow propagation direction of anisotropy

Integration of 115 years of deformation data reveals subsidence up 50 cm/year in Mexico City

The majority of the subsidence is irreversible and its rates are linearly correlated to the thickness of the upper aquitard

Migration of low-quality water to the productive aquifer sets the stage for a water crisis, which influences the socioeconomic landscape
