The last weeks brought some good news for the Perigeo crew, with a bunch of new papers that just came out. We’re very happy also because all the papers are led by early career scientists! Two papers deal with the house specialty, earthquake environmental effects and the ESI scale; then, Alpine structural geology and water…

Earthquakes produce a large variety of environmental effects, such as surface faulting, landslides, liquefaction. Primary effects are related to the surface expression of the seismogenic source and includes surface faulting and permanent ground deformation (uplift or subsidence). Secondary effects are mostly caused by ground shaking and include 8 categories: ground cracks, slope movements, liquefaction processes,…

“La pioggia fa sul serio” è un giallo ambientato nell’Appennino tosco-emiliano scritto da Francesco Guccini e Loriano Macchiavelli. In questo caso, Appennino o Prealpi non fa molta differenza, la dimostrazione di quanto la pioggia possa “fare sul serio” ci è stata data pochi giorni fa, quando il Comasco è stato investito da abbondanti piogge, che…

The e-poster is titled “Use of InSAR measurements for vulnerability analysis of buildings exposed to subsidence in Como urban area (northern Italy)” and is part of a recently published work on subsidence in Como. The research involved the University of Insubria, the University of Salerno, INGV, and ISPRA. Come meet us on Wednesday 2 June…

I nostri geologi del gruppo PeriGeo dell’Università dell’Insubria sono sulle tracce delle faglie attive e capaci per la Ricostruzione post-sisma 2016. Il post originale è al seguente link.
Our last paper titled “Distributed faulting following normal earthquakes: reassessment and updating of scaling relations” is now online and open for discussion on EGU Solid Earth journal! Why distributed faulting? Earthquake damage can be ascribed to 2 different mechanisms: surface faulting and the passage of seismic waves. Surface faulting occurs whenever a rupture reaches the…

Anche quest’anno abbiamo riproposto il progetto PCTO “Citizen Geology”, in cui alcuni ragazzi delle scuole superiori vengono coinvolti nelle attività di ricerca del gruppo di Geologia Ambientale. Sei ragazzi del Liceo Galilei di Erba su sono impegnati (e anche tanto!) nell’analisi di un terremoto avvenuto nel 2015 in Malesia, e in particolare nella mappatura delle…

The ruins of the Roman theater and city gates of Tiberias (Israel, along the western shores of the Sea of Galilee) were over there, firstly dug and studied in the early ’80s, waiting for the eyes of earthquake scientists to whisper their secret. The story of an old, destructive earthquake that caused surface faulting at…

Over the years, the subsidence affecting the Como urban area in northern Italy has been investigated by several research groups. The major factors inducing this phenomenon in Como basin are i) the thick sequence of reworked material and ii) unconsolidated silty clay sediments with poor mechanical properties, and iii) the variations of the piezometric level.…

We live in an era of hypertrophic information; we are submerged by data and in many cases the limiting factor to analyses is computational power rather than data availability. This is not the case for historical earthquakes: coeval sources are usually fragmentary, and descriptions may not be crystal clear. Depending on their specialty, Earth scientists…
