New papers!

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…

A database of the earthquakes analyzed using the ESI-07 scale

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,…

Dissesto idrogeologico nel Comasco

“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…

New paper online – discussion open

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…

Progetto PCTO “Citizen Geology”

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…

New paper on the reliability of Earthquake Environmental Effects for analyzing historical events

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…

Debris flow a Chiareggio (So)

Il 12 agosto 2020 un debris flow ha investito due auto causando la morte di tre persone in località Chiareggio (frazione di Chiesa Valmalenco, provincia di Sondrio). L’evento è stato causato dalle ingenti precipitazioni (18.8 mm di pioggia registrati tra le 17 e le 18 alla stazione di Chiesa Valmalenco – S. Giuseppe, Figura 1).…

Developing the First Intensity Prediction Equation Based on the Environmental Scale Intensity

The Perigeo research group is excited for the second paper published in one week! In this paper, we analyze earthquake effects through the ESI (Environmental Seismic Intensity) scale for 14 events in the Central and Southern Apennines… this is one of the strong points of the group, so no surprise at all! We develop an…

Assessment of attenuation regressions for earthquake-triggered landslides in the Italian Apennines

A new Perigeo-branded paper is now online! The paper is available here; if you can’t wait, here’s a summary of the main outcomes! AAAAnd stay tuned, next week a new post on another paper! The Apennines are prone to earthquakes, and earthquakes commonly produce landslides. How the number of landslide decay with distance from the…

Two upcoming projects

Good news from our research group! We are pleased to announce that Elisa Martinelli and Magda Velazquez have been appointed a 1-year post-doc position! Elisa will lead a project on “Palaeobotanical methods to investigate human impact and “catastrophic” environmental events in the Como basin (N-Italy) since the Roman Period”, while Magda will focus on “Environmental…
