Short summary
Short summary
The latest satellite technology with longer wavelength radar improves our ability to detect and monitor large alpine rock slope instabilities. This approach works better than current satellite systems in forested areas and on fast-moving slopes, giving experts more reliable data to understand these major hazards. Our results from three locations in Italy and Switzerland also provide important recommendations for the preparation of future satellite radar missions.

This paper documents a monitoring network of 54 positions, located on different periglacial landforms in the Swiss Alps: rock glaciers, landslides, and steep rock walls. The data serve basic research but also decision-making and mitigation of natural hazards. It is the largest dataset of its kind, comprising over 209 000 daily positions and additional weather data.

The paper presents the results of recent geoarchaeological studies on the Ticino river alluvial plain. The sedimentological descriptions are combined with archaeological observations and constrained with radiocarbon dating. This approach, together with data from previous research and historical sources, provides an interesting overview of the eveolution of Ticino river morphosedimentary dynamics in relation to human settlements since the Neolithic.

Short summary
Exposure ages make it possible to determine the time of weathering of a rock surface. They can be determined from rebound values measured with the Schmidt hammer and calibrated on surfaces of known age, defined in this study thanks to historical cartography and two mule tracks built in 300 and 1250 CE, which allowed us to reconstruct glacier fluctuations over the last 3 centuries in Val Scaradra and to define the time of deglaciation and rock glacier development in the Splügenpass region.

Short summary
The Monte Crenone rock avalanche of 1513 is well known on the southern side of the Alps because in 1515 it generated the largest inundation that has occurred in Switzerland in the Common Era, the Buzza di Biasca. New geological and historical observations allowed the setup of a numerical model of this major event, permitting a better definition of the chain of consequences that affected the alluvial plain of the river Ticino from Biasca to Lake Maggiore between the 16th and the 19th century.
