Scientists earlier birth date Earth tectonic plates
2020/6/5
Geophysicists funded by the National Science Foundation have reported that Earth's ever-shifting, underground network of tectonic plates was firmly in place more than 4 billion years ago -- at least a...
Tectonic plates started shifting earlier than previously thought(图)
Tectonic plates started shifting previously thought
2020/5/9
An enduring question in geology is when Earth's tectonic plates began pushing and pulling in a process that helped the planet evolve and shaped its continents into those that exist today. Some researc...
Tectonic shift?
Tectonic shift
2016/12/27
Plate tectonics, the idea that the surface of the Earth is made up of plates that move apart and come back together, has been used to explain the locations of volcanoes and earthquakes since the 1960s...

SW iberia continental margin seismicity tsunami tectonic structures
2015/10/8
The SW continental margin of Iberia is affected by several tectonic structures of Cenozoic to Recent age, gen-erated by the dynamics of the Iberia-Africa plate margin. This activity is testified by di...
Analysis of the seismicity of Southeastern Sicily: a proposed tectonic interpretation
Historical seismicity Macroseismics source parameters quaternary tectonics seismogenic faults hyblean plateau SE Sicily
2015/9/30
Southeastern Sicily is one of the Italian regions with high seismic risk and is characterised by the occurrence in the past of large destructive events (MS = 6.4-7.3) over a territory which is densely...
Palaeomagnetic results from an archaeological site near Rome (Italy): new insights for tectonic rotation during the last 0.5 Myr

2015/9/15
Approximately 20 km north-east of Rome, along the modern trace of the Tiburtina road, recent archaeological diggings have brought to light a system of aqueduct galleries constructed by Roman engineers...
Resistivity and heterogeneity of Earth crust in an active tectonic region,Southern Tuscany (Italy)
crustal exploration magnetotellurics geothermal areas
2015/9/14
Southern Tuscany, belonging to the inner zone of the Northern Apennines, Italy, is an ideal laboratory for observing the physical features of the lithosphere and their evolution in tectonically active...
Comparison between active stress field and tectonic structures in Northern Italy, Lombardy Region

The aim of this work is to understand the complex pattern of active stress field orientations revealed by borehole
breakout analysis with respect to the tectonic structures in a wide region of Northe...
Estimates of fluid pressure and tectonic stress in hydrothermal/volcanic areas:a methodological approach
hydrothermal fluids faults cracks fluid pressure volcanic/hydrothermal areas seismicity
2015/9/10
An analytical approach to estimate the relative contribution of the fluid pressure and tectonic stress in hydrothermal/
volcanic areas is proposed assuming a Coulomb criterion of failure. The analyti...
