Abstract Rainfall-triggered landslides pose a significant threat to both infrastructure and human lives, making it crucial comprehend the factors that contribute their occurrence. Specifically, understanding relationship between these amount of rain is necessary for triggering such events essential effective prediction mitigation strategies. To address this issue, our study proposes statistical modelling approach using machine learning, specifically Random Forest algorithm, investigate...
The scope of this work is to carry out a morphometric analysis Pluto’s impact craters. A global Pluto digital elevation model (DEM) with resolution 300 m/px, created from stereoscopic pairs obtained by the New Horizons Mission, was used extract data surface divided according different characteristics in order analyze possible differences dynamics and modification rate each region. Python code developed, within QGIS 3× software environment, automate process crater outlining collection data:...
Serra Pelada is the newest Brazilian eucrite and first recovered fall from Amazonia (State of Pará, Brazil, June 29th 2017). In this paper, we report on its petrography, chemistry, mineralogy magnetic properties. Study four thin sections reveals that meteorite brecciated, containing basaltic gabbroic clasts, as well recrystallized impact melt, embedded into a fine-medium grained matrix. Chemical analyses suggest monomict eucritic breccia, normal member HED suite. Our results provide...
Flash floods are often responsible for deaths and damage to infrastructure. The general objective of this work is create data-based models understand how the predisposing factors influence triggering factor (precipitation) in case flash continental area Portugal. occurrences were extracted from DISASTER database, which contains location date historical flood events study region. Historical daily rainfall data was collected automatically Copernicus database. We accumulated precipitation 3...
The Parauapebas meteorite, third official meteorite discovered in the Brazilian Amazon region, is a “hammer meteorite” which fell on December 9th, 2013, city of Parauapebas, Pará State, Brazil. Mineralogy dominated by forsterite, enstatite, iron, troilite, and tetrataenite. Albite, chromite, diopside, augite, pigeonite, taenite, merrillite are minor components. Two main clasts separated black shock-induced melt veins. One clast exhibits an abundance chondrules with well-defined margins set...
Shallow landslides are geological phenomena that affect soil of small thickness originated from the weathering bedrock and downslope transportation. The goal this work is to analyze correlation between conditioning factors triggering factor (rainfall) shallow in continental area Portugal. understanding these can be great help for development early warning systems, since it enables near real time updates susceptibility maps relying on rainfall forecast the  specific physical...
