Features of terraces and the incision rate along the lower reaches of the Yarlung Zangbo River east of Namche Barwa: Constraints on tectonic uplift

Open Geosciences, 2020
Along the lower reaches of the Yarlung Zangbo River, scattered alluvium sections appear on T1 and T2 terraces. The alluvial deposits on the T1 terrace in Linduo and Ximogou and the T2 terrace in Guoguotang are composed principally of coarse-grained sand ...

Seismic reliability assessment of classical columns subjected to near-fault ground motions [PDF]

, 2013
A methodology for the performance-based seismic risk assessment of classical columns is presented. Despite their apparent instability, classical columns are, in general, earthquake resistant, as proven from the fact that many classical monuments have ...

From repair costs and casualties to human displacements in the aftermath of an earthquake. The case of buildings with and without pre-existing damage exposed to a Mw 7.1 scenario in the Messina Strait, Italy

Geomatics, Natural Hazards & Risk
In seismic risk assessment, expert-elicited collapse factors are used to estimate casualties (injuries and fatalities). However, these approaches often overlook buildings’ pre-existing (pre-earthquake) deterioration.

The 1730 Great Metropolitan Chile Earthquake and Tsunami Commemoration: Joint Efforts to Increase the Country’s Awareness

Geosciences, 2020
On 8 July 1730, a great earthquake struck metropolitan Chile, causing extensive damage 1000 km along the country and focused in Valparaíso. Due to the date of occurrence of this event, large uncertainties about the earthquake’s magnitude have been ...

Microzoning Tsunami Hazard by Combining Flow Depths and Arrival Times

Frontiers in Earth Science, 2021
Tsunami hazard is typically assessed from inundation flow depths estimated from one or many earthquake scenarios. However, information about the exact time when such inundation occurs is seldom considered, yet it is crucial for pedestrian evacuation ...

Natural Time, Nowcasting and the Physics of Earthquakes: Estimation of Seismic Risk to Global Megacities

, 2017
This paper describes the use of the idea of natural time to propose a new method for characterizing the seismic risk to the world's major cities at risk of earthquakes. Rather than focus on forecasting, which is the computation of probabilities of future

Assessment of Frost Depth and Frost Heave in Romania

Applied Sciences
The investigation of extreme weather and climate events has gained momentum in the last few decades, spurred in part by political involvement. However, not enough attention has been paid to the historical recorded data of climate monitoring.

Modelling seismic ground motion and its uncertainty in different tectonic contexts: challenges and application to the 2020 European Seismic Hazard Model (ESHM20) [PDF]

Natural Hazards and Earth System Sciences
Current practice in strong ground motion modelling for probabilistic seismic hazard analysis (PSHA) requires the identification and calibration of empirical models appropriate to the tectonic regimes within the region of application, along with ...

Uncharted seismic risk

Nature Geoscience, 2011
The potential for earthquakes along the plate boundaries has been mapped with reasonable success. Our attention should now focus on the threat posed by unanticipated quakes located in the continental interiors.
