How asteroid, comet strikes may have delayed evolution of atmosphere（图）
小行星 彗星撞击 大气科学 高层大气物理学
2023/6/21
Between 2.5 and 4 billion years ago, a time known as the Archean eon, Earth’s weather could often be described as cloudy with a chance of asteroid.
Back then, it was not uncommon for asteroids or com...
COASTLINE DETECTION USING FUSION OF OVER SEGMENTATION AND DISTANCE REGULARIZATION LEVEL SET EVOLUTION
Coastline DRLSE FOOS K-means Clustering Sea-land Segmentation Wavelet Transform
2018/4/18
Coastline detection is a very challenging task in optical remote sensing. However the majority of commonly used methods have been developed for low to medium resolution without specification of the ke...
Dynamical tools for the analysis of long term evolution of volcanic tremor at Stromboli
non linear analysis volcano trtemor state space reconstruction delayed coordinates
2015/10/8
Stromboli is characterized by persistent seismic activity, both in terms of tremor and of discrete events associated with moderate explosions defining the so-called "Strombolian activity". This kind o...
In search of evidence of deep fluid discharges and pore pressure evolution in the crust to explain the seismicity style of the Umbria-Marche 1997-1998 seismic sequence (Central Italy)
fluid geochemistry/seismicity porepressure field Umbria-Marche 1997-1998 seismic sequence
2015/9/30
Starting soon after the first main-shocks of the long seismic sequence which has occurred along the Umbria-Marche boundary since September 1997, fluid geochemistry surveying was accomplished (around 2...
Evolution of magnetotelluric,total magnetic field,and VLF field parameters in Central Italy:relations to local seismic activity
Magnetotelluroc tectonomagnetism VLF waves
2015/9/28
Magnetotelluric data were collected at Collemeluccio (41.72°N, 14.37°E) in Central Italy from summer 1991 to spring 1998. Analyzed by means of tensor decomposition on the geoelectric potential and rob...
The Southern Tyrrhenian subduction system: recent evolution and neotectonic implications
subducted slab lithospheric tears neotectonics vertical motions seismicity
2015/9/28
Geological and geophysical data have been integrated with the aim of presenting a new evolutionary model for the Southern Tyrrhenian and adjacent regions. The Southern Tyrrhenian backarc basin opened ...
Effects of repeated paleoearthquakes on the Alhama de Murcia Fault (Betic Cordillera, Spain) on the Quaternary evolution of an alluvial fan system
paleoseismicity slow active faults fan morphology Alhama de Murcia Fault BeticCordillera
2015/9/16
In this work we present a study of an alluvial fan system, which is affected by the Quaternary activity of the leftlateral,reverse Alhama de Murcia Fault (Betic Cordillera). Paleoseismic studies in th...
Evolution of the volcanic plumbing systemof Alicudi (Aeolian Islands - Italy): evidence from fluid and melt inclusionsin quartz xenoliths
Aeolian Islands fluid inclusions crustal xenoliths homogenisation temperature magma plumbing system
2015/9/15
Quartz-rich xenoliths in lavas (basalts to andesites; 90-30 ka) from Alicudi contain abundant melt and fluid inclusions. Two generations of CO2-rich fluid inclusions are present in quartz-rich xenolit...
