Abstract. Rockfalls are a ubiquitous geomorphic process and a natural hazard in steep landscapes across the globe. Seismic monitoring can provide precise information on the timing, location and event anatomy of rockfalls, which are parameters that are otherwise hard to constrain. By pairing data from 49 seismically detected rockfalls in the Lauterbrunnen Valley in the Swiss Alps with auxiliary meteorologic and seismic data of potential triggers during autumn 2014 and spring 2015, we are able to (i) analyse the evolution of single rockfalls and their common properties, (ii) identify spatial cha

The assessment of rockfall risks on human activities and infrastructure is of great importance. Rock falls pose a significant risk to (a) transportation infrastructure, (b) inhabited areas, and (c) Cultural Heritage sites. The paper presents a method to assess rockfall susceptibility at national scale in Greece, using a simple rating approach and Geographic Information Systems (GIS) techniques. An extensive inventory of rockfalls for the entire country was compiled for the period between 1935 and 2019.

Rockfall processes are now commonly studied through monitoring campaigns using repeat lidar scanning.

Thus, the assessment of their probability of occurrence is a major challenge for risk management.

Nevertheless, from a quantitative perspective, these generally assumed correlations between rockfalls and their possible meteorological triggering events are often difficult to identify because (i) rockfalls are too rare for the use of

The complementary cumulative distribution of the rockfall volume is well fitted by a power law, with an exponent b of 0.75 ± 0.04. In order to compare the rockfall frequencies in different geological contexts, a rockfall activity parameter has been defined, which is the number of rockfalls larger than 1 m3, which occur per century and per hm2.

The present thesis aims at the analysis of the fragmentation of rockfalls. The fragmentation is a complex phenomenon poorly understood with a lack of tools to reproduce it on rockfall simulators. The effect of fragmentation on the hazard assessment and mapping is significant and it may substantially modify the risk scenario. The analysis of the empirical data acquired in a series of inventoried natural rockfalls and real-scale drop tests, clearly suggests that fragmentation displays a fractal behavior.

Rockfalls is a major problem around the world, if they occur in populated areas, they can cause major damage to infrastructure, injure or kill people. For this reason, it is important to be able to predict where the risk of rockfalls and how to prevent and protect populated areas from them. However, it is no easy task to predict rockfalls. Although if an area with potential area for rockfall is localized it may seem easy to construct protective meshing or bolting potential blocks down.

These consist of electrical sensing wires strung on poles located uphill of the track; falling rocks snap these wires and trigger an alarm.

ABSTRACT: Rockfalls pose a critical risk to the mining industry. In collaboration with NIOSH and industry partners, the Geotechnical Center of Excellence (GCE) has previously shown that thermal video can effectively observe rockfall events. Currently, work is underway to automate the detection, tracking, and alarming of these events. To facilitate this work, a prototype thermal imaging system that uses an early version of the detection algorithm has been developed. Designed to withstand extreme environments, the system can be easily transported with a light vehicle and installed in under 20 mi

Abstract:
ABSTRACT: Rockfalls are naturally occurring geohazards that are frequently associated with steep or vertical slopes. Falling rocks have the potential to disrupt transportation systems, including highway and railway passages. A common trigger known to influence the frequency and severity of rockfall events is precipitation. For many rock slopes, rainfall is considered the primary rockfall trigger. In some cases, the relationship between rainfall amount and rockfall frequency presents as a linear correlation when studied using data averaged over an extended period (i.e. due to monitoring data re

Acrocorinth is a steep rock 575m high that dominates the plain of the modern and ancient city of Corinth, in Greece. Today it is one of the most important archaeological sites in Greece, with a lot of visitors. The entrance area of the archaeological site is located at the entry point of the Castle, where for defensive reasons it was originally built in a position where it is particularly exposed to all kinds of natural hazards and rockfalls. This paper analyzes the risks posed by rock falls (2) in the entrance area of the archaeological site, the footbridge and the visitor access road and exa

Abstract:
Abstract Rockfalls pose significant challenges and hazards to railways and recognizing and monitoring landslide-prone areas is crucial for effective disaster mitigation. Small Baseline and Subset (SBAS), is an advanced subset of the Interferometric Synthetic Aperture Radar (InSAR) technique, that can measure small displacements and effectively detect landslides. However, relying solely on a single-point deformation reading increases result uncertainty and the potential for incorrect judgments in landslide recognition. This paper introduces two novel approaches to address this concern: SBAS thr

Abstract:
The November 1st, 1935, Témiscaming earthquake occurred within 20 km of the town of Témiscaming, Quebec. This earthquake was felt west to Fort William (now part of Thunder Bay), Ontario, east to Saint John, New Brunswick, and south to Kentucky and Virginia. Damaged chimneys were reported in Témiscaming, Quebec, and North Bay and Mattawa, Ontario. In the epicentral region, rockfalls were observed as well as cracks in gravel and sand along the shores of islands and lakes. Some 350 km away from the epicentre, near Parent, Quebec, earthquake vibrations triggered a 30 metre slide of railroad embank

Abstract:
This paper aims to present a few aspects of the development of a plastic-hardening macro-element model for steel wires in flexible protection systems. First, the material behaviour is obtained using uniaxial tensile tests. Successively, the evolution of the elastic and plastic domain is obtained using a combination of physical tests, analytical models, and numerical simulations. Finally, the results obtained with the macro-element model are compared to those obtained using other approaches found in literature.
