HIGH-RESOLUTION ENHANCED PRODUCT BASED ON SMAP ACTIVE-PASSIVE APPROACH USING SENTINEL 1A AND 1B SAR DATA
soil moisture microwave remote sensing active-passive algorithm SMAP Sentinel-1A -1B
2019/2/27
SMAP project released a new enhanced high-resolution (3km) soil moisture active-passive product. This product is obtained by combining the SMAP radiometer data and the Sentinel-1A and -1B Synthetic Ap...
Supervolcanoes like Yellowstone may have been more active in the past
Supervolcanoes Yellowstone more active in the past
2016/6/12
Geophysical monitoring of the ground above active supervolcanoes, like the one located in Yellowstone National Park, shows that it rises and falls as magma moves beneath the surface of the Earth.Magma...
Months of warning signs from Mauna Loa, on Hawaii’s Big Island, prompted the U.S. Geological Survey to recently start releasing weekly updates on activity at the world’s largest active volca...
Anomalous pattern of geochemical data recorded in the seismically active site of Pieschi (Southern Italy)
earthquakes geochemical signals time series
2015/9/2
This work explores three years of geochemical signals recorded by Pieschi station (Southern Italy). The measuring
station is located in a thermal spring located in the Southern Apennines Chain, one o...
Strategies in the processing and analysis of continuous gravity record in active volcanic areas: the case of Mt. Vesuvius
time gravity changes gravity record volcanic processes air pressure admittance
2015/9/1
This research is intended to describe new strategies in the processing and analysis of continuous gravity records
collected in active volcanic areas and to assess how permanent gravity stations can i...
Surface deformation of active volcanic areas retrieved with the SBAS-DInSAR technique: an overview
Ground deformation Differential Interferometry
2015/9/1
This paper presents a comprehensive overview of the surface deformation retrieval capability of the Differential
Synthetic Aperture Radar Interferometry (DInSAR) algorithm, referred to as Small BAsel...
Geochemical monitoring of volcanic lakes. A generalized box model for active crater lakes
Geochemical monitoring Active crater lakes Box model Mass budget Isotope and chemical budget
2015/8/27
In the past, variations in the chemical contents (SO42−, Cl−, cations) of crater lake water have not systematically demonstrated any relationships with eruptive activity. Intensive paramet...
Monitoring active volcanoes: The geochemical approach
Active volcanoes geochemistry volcanic activity lava dissolving volatiles
2015/8/27
The geochemical surveillance of an active volcano aims to recognize possible signals that are related to changes in volcanic activity. Indeed, as a consequence of the magma rising inside the volcanic ...
Active tectonics around the Mediterranean region: site studies and application of new methodologies
Mediterranean region site studies
2015/8/26
More than 25 years have passed since the definition of Active Tectonics as "tectonic movements that are expected to occur within a future time span of concern to society", formulated in a milestone bo...
Active faulting and transpression tectonics along the plate boundary in North Africa
Tell Atlas North Africa Plate boundary Transpression
2015/8/26
We present a synthesis of the active tectonics of the northern Atlas Mountains, and suggest a kinematic model of transpression and block rotation that illustrates the mechanics of this section of the ...
Active compressional tectonics, Quaternary capable faults, and the seismic landscape of the Po Plain (northern Italy)
Active compressional tectonics paleoseismology seismic hazard Po Plain foredeep seismic landscape
2015/8/26
It is commonly believed that the Po Plain is an area of low seismic hazard. This conclusion is essentially a combination of two factors: (1) the historical record of earthquakes, which shows a relativ...
Propagation of Localization Instability Under Active and Passive Loading
Constitutive models Finite element method Limit analysis Banding Plasticity Localization Strain distribution Retaining walls
2015/7/1
The mechanical response of a solid continuum changes drastically as the deformation evolves from a diffuse state to a highly localized state. For this reason the subject of strain localization has rec...
Volcanoes, including Mount Hood, can go from dormant to active quickly（图）
Volcanoes including Mount Hood dormant
2014/3/20
A new study suggests that the magma sitting 4-5 kilometers beneath the surface of Oregon's Mount Hood has been stored in near-solid conditions for thousands of years, but that the time it takes to liq...
