Digital Earth is a global initiative to construct a comprehensive virtual representation of the planet. It is a collaborative effort between Earth sciences, space sciences and information sciences to ...
Long Period Tidal Force Variations and Regularities in Orbital Motion of the Earth-Moon Binary Planet System
Long Period Tidal Force Variations and Regularities Orbital Motion the Earth-Moon Binary Planet System Geophysics
2012/5/28
We have studied long period, 206 and 412 day, variations in tidal sea level corresponding to various moon phases collected from five observatories in the Northern and Southern hemispheres. Variations ...
Origin of giant wave ripples in snowball Earth cap carbonate
Origin of giant wave ripples snowball Earth cap carbonate
2014/4/8
The most extreme climate transitions in Earth history are recorded by the juxtaposition of Neoproterozoic glacial deposits with overlying cap carbonate beds. Some of the most remarkable sedimentary st...
Measurement requirements for a near-Earth asteroid impact mitigation demonstration mission
Near-Earth Asteroids Impact Mitigation Spacecraft Missions
2011/8/17
Abstract: A concept for an Impact Mitigation Preparation Mission, called Don Quijote, is to send two spacecraft to a Near-Earth Asteroid (NEA): an Orbiter and an Impactor. The Impactor collides with t...
A generalized Bak-Sneppen model for Earth's magnetic field reversals
Bak-Sneppen model Earth's magnetic field
2011/9/6
We introduce a simple model for Earth’s magnetic field reversals. The model consists in random nodes simulating vortices in the liquid part of the core which through a simple updating algorithm conver...
Triggering of Aftershocks of the Japan 2011 Earthquake by Earth Tides
Japan 2011 earthquake, Aftershock Triggering, Earth tides
2011/9/1
The aftershock sequence of the devastating Japan earthquake of March 2011 is analyzed for the presence of periodicities at the Earth tide periods. We use spectral analysis as well as a time-domain met...
Accurate Measurement in the Field of the Earth of the General-Relativistic Precession of the LAGEOS II Pericenter and New Constraints on Non-Newtonian Gravity
General-Relativistic Pericenter Constraints on Non-Newtonian Gravity
2011/9/14
The pericenter shift of a binary system represents a suitable observable to test for possible deviations from the Newtonian inverse–square law in favor of new weak interactions between macroscopic obj...
Corrigendum to "Applying and validating the PTVA-3 Model at the Aeolian Islands, Italy: assessment of the vulnerability of buildings to tsunamis" published in Nat. Hazards Earth Syst. Sci., 10, 1547–1562, 2010
the PTVA-3 Model , Italy assessment the vulnerability of buildings tsunamis
2010/10/21
The volcanic archipelago of the Aeolian Islands (Sicily, Italy) is included on the UNESCO World Heritage list and is visited by more than 200 000 tourists per year. Due to its geological characteristi...
Connection of large earthquakes occurring moment with the movement of the Sun and the Moon and with the Earth crust tectonic stress character
Connection large earthquakes occurring moment the movement of the Sun the Moon with the Earth crust tectonic stress character
2010/10/21
It is acceptable that earthquakes certain exogenous (cosmic) triggering factors may exist in every seismoactive (s/a) region and in Caucasus among them. They have to correct earthquake occurring momen...
Numerical earthquake response analysis of the Liyutan earth dam in Taiwan
Numerical earthquake response analysis the Liyutan earth dam Taiwan
2010/10/20
The dynamic response of the Liyutan earth dam to the 1999 Chi-Chi earthquake (ML=7.3) in Taiwan was numerically analyzed. First, the staged construction of the dam was simulated. Then, seepage analysi...
Earth's magnetic field older than we thought（图）
Earth's magnetic field the planet's core the ancient field
2010/3/26
Earth's magnetic field, which shields us from the Sun's deadly rays, emerged from the planet's core even earlier in Earth's history than we previously thought. While this field, 3.45 billion years ago...
Zonal flows are ubiquitous in nature. Familiar examples include the jet stream winds that circulate the globe or the alternating currents in the world's oceans such as the Gulf Stream. Now, researcher...
Sun's appetite for dark matter may affect Earth's orbit（图）
Sun's appetite dark matter Earth's orbit
2010/1/26
Calculations made by a physicist in Italy suggest that the Sun is sucking up significant quantities of dark matter and this is causing observable changes to Earth's orbit. This latest research predict...
