Humidity dependence of AE activity in sheared quartz gouges and its implication for the micromechanics of friction

Earth, Planets and Space
The micromechanics of friction has been investigated from the viewpoint of the healing of real contacts. In this study, the underlying processes of friction are discussed from the viewpoint of the contact junction deformation and failure by measuring the

Climate model simulation of winter warming and summer cooling following the 1991 Mount Pinatubo volcanic eruption

, 1999
We simulate climate change for the 2-year period following the eruption of Mount Pinatubo in the Philippines on June 15, 1991, with the ECHAM4 general circulation model (GCM).

Ecosystem recharge by volcanic dust drives broad-scale variation in bird abundance [PDF]

, 2015
Across the globe, deserts and volcanic eruptions produce large volumes of atmospheric dust, and the amount of dust is predicted to increase with global warming.

Sulfur mass loading of the atmosphere from volcanic eruptions: Calibration of the ice core record on basis of sulfate aerosol deposition in polar regions from the 1982 El Chichon eruption [PDF]

Major volcanic eruptions disperse large quantities of sulfur compound throughout the Earth's atmosphere. The sulfuric acid aerosols resulting from such eruptions are scavenged by snow within the polar regions and appear in polar ice cores as elevated ...

Initial atmospheric conditions control transport of volcanic volatiles, forcing and impacts [PDF]

Atmospheric Chemistry and Physics
Volcanic eruptions impact the climate and environment. The volcanic forcing is determined by eruption source parameters, including the mass and composition of volcanic volatiles, eruption season, eruption latitude, and injection altitude.

The global magnitude–frequency relationship for large explosive volcanic eruptions

, 2018
For volcanoes, as for other natural hazards, the frequency of large events diminishes with their magnitude, as captured by the magnitude–frequency relationship.

Probabilistic enhancement of the Failure Forecast Method using a stochastic differential equation and application to volcanic eruption forecasts

, 2018
We introduce a doubly stochastic method for performing material failure theory based forecasts of volcanic eruptions. The method enhances the well known Failure Forecast Method equation, introducing a new formulation similar to the Hull-White model in ...

Explosive volcanism, shock metamorphism and the K-T boundary [PDF]

The issue of whether shocked quartz can be produced by explosive volcanic events is important in understanding the origin of the K-T boundary constituents.

Role of a Hidden Fault in the Early Process of the 2024 Mw7.5 Noto Peninsula Earthquake

Geophysical Research Letters
The 2024 Mw 7.5 Noto Peninsula, Japan, earthquake was initiated within the source region of intense swarm activity. To reveal the mainshock early process, we relocated the earthquake hypocenters and found that many key phenomena, including the mainshock ...
