Exceedance Probabilities for Large Earthquakes from DIY Local Earthquake Ensemble Nowcasting and Forecasting: Magnitude, Natural Time, and Calendar Time
In this paper, we describe a method for computing calendar time forecasts in a local area for large earthquakes of a target magnitude MT using a count of small earthquakes in the magnitude range MS to MT in the area. Using the idea that the Gutenberg–Richter (GR) relation is valid throughout the…

Efficient Mitigation Measures for Reducing the Kinematic Distress of Offshore Pipelines Due to Seismic Fault Rupture
Offshore high-pressure gas pipelines comprise critical infrastructure that often cross seismic regions for hundreds of kilometers. The intersection of such pipelines with seismic fault zones is frequently inevitable due to high costs or technical constraints of alternative routes. While typical…

Communicating the “Last Mile” of Seismic Risk: Insights from a Case Study
Earthquake risk communication often remains centered on event parameters and structural collapse, while local site effects, building response and non-structural elements vulnerability shape how earthquakes are experienced and what people can do to reduce risk. This study examines whether a…

Rockfall Volume–Cumulative Frequency Relationships for Rockfall Hazard Quantification Using Historical and Change Detection Data
Rockfall records for hazard assessments commonly present rockfall volume–cumulative frequency curves based on observations of rockfall occurrences that are noticed at or in the vicinity of infrastructure. These curves are in log–log scale, where the curves for larger volumes are fitted to a power…

Toward an Automatic Pixel-Based Detection of Earthquake-Triggered Landslides in Arid Environments Using Optical Imagery
Seismically triggered landslides represent a major secondary hazard of earthquakes, often causing widespread damage over large areas. Rapid and reliable mapping of such phenomena is therefore essential, particularly in emergency contexts. While numerous studies have addressed landslide detection in…

The Occurrence of Widespread Slush Flow Events as an Indicator of Accelerating Climate Change in the Northwestern Italian Alps
Slush flows are rapid mass movements of water-saturated snow and debris that develop when the liquid water content of the snowpack exceeds the critical threshold for the fully funicular regime, resulting in viscoplastic flow behavior fundamentally distinct from that of dry snow avalanches. These…

Automatic Sentiment Analysis of Citizen Comments: The Case of the Albania Earthquake
Collecting and analysing data after an earthquake is essential to determine its impact. In 2014, the European Mediterranean Seismological Centre launched the LastQuake system. Its app collects reports on the intensity users feel, along with comments that provide situational awareness. However, text…
