TLDR
In this article, the authors reviewed the seismotectonic setting and regional seismicity in Nepal and analyzes available aftershock data and ground motion data to gain deeper understanding of the observed earthquake damage in Nepal.Abstract:
The 2015 Gorkha Nepal earthquake caused tremendous damage and loss. To gain valuable lessons from this tragic event, an earthquake damage investigation team was dispatched to Nepal from 1 May 2015 to 7 May 2015. A unique aspect of the earthquake damage investigation is that first-hand earthquake damage data were obtained 6 to 11 days after the mainshock. To gain deeper understanding of the observed earthquake damage in Nepal, the paper reviews the seismotectonic setting and regional seismicity in Nepal and analyzes available aftershock data and ground motion data. The earthquake damage observations indicate that the majority of the damaged buildings were stone/brick masonry structures with no seismic detailing, whereas the most of RC buildings were undamaged. This indicates that adequate structural design is the key to reduce the earthquake risk in Nepal. To share the gathered damage data widely, the collected damage data (geo-tagged photos and observation comments) are organized using Google Earth and the kmz file is made publicly available.read more

A global slope unit-based method for the near real-time prediction of earthquake-induced landslides
TL;DR: In this article, a set of 25 earthquake-induced landslide-events are selected and categorized based on the similarity between causal factors to determine the most relevant training set to make a prediction for a given landslide-event.
Journal ArticleDOI
An updated method for estimating landslide-event magnitude
TL;DR: In this article, the authors used a much larger collection of earthquake-induced landslide (EQIL) inventories (n=45) than previous studies to show that size distributions are much more variable than previously assumed.

Review Article Topographic Slope as a Proxy for Seismic Site Conditions and Amplification
David J. Wald,Trevor I. Allen +1 more
TL;DR: In this paper, a technique to derive first-order site-condition maps from topographic data is described, where the average shear-velocity down to 30 m is correlated against topographic slope to develop two sets of parameters for deriving VS 30 : one for active tectonic regions where to-pographic relief is high, and one for stable shields where topography is sparse.

TL;DR: In this article, the size and location of northern Indian and southern Tibetan earthquakes during the last 200 years is evaluated. But the authors focus on assessing intensity of early and more recent earthquakes in a built environment and to the way in which isoseismals are drawn.
