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! Archeoseismology in the Dead Sea Zone.

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…

New paper on Subsidence in Como basin (N Italy)

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.…

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…
