Broadscale postseismic gravity change following the 2011 Tohoku-Oki earthquake and implication for deformation by viscoelastic relaxation and afterslip
The analysis of GRACE gravity data revealed postseismic gravity increase by 6 μGal over a 500 km scale within a couple of years after the 2011 Tohoku-Oki earthquake, which is nearly 40-50% of the coseismic gravity change. It originates mostly from changes in the isotropic component corresponding to the Mrr moment tensor element. The exponential decay with rapid change in a year and gradual chan...
متن کاملViscoelastic suppression of gravity-driven counterflow instability.
Attempts to achieve "top kill" of flowing oil wells by pumping dense drilling "muds," i.e., slurries of dense minerals, from above will fail if the Kelvin-Helmholtz instability in the gravity-driven counterflow produces turbulence that breaks up the denser fluid into small droplets. Here we estimate the droplet size to be submillimeter for fast flows and suggest the addition of a shear-thickeni...
متن کاملEffect of black surfaces to increase the average surface temperature of the earth: A global warning!
Gradual increase of the Earth's surface temperature can cause many significant changes on the climate of our planet. This problem is progressively increasing. One of the main reasons for this phenomenon is the absorption of the Sun's energy and lack of proper reflection of emissions due to man-made activities, one of which is the increase in black surfaces. In this descriptive and cross-sectio...
متن کاملEarth ’ S Global Energy
W eather and climate on Earth are determined by the amount and distribution of incoming radiation from the sun. For an equilibrium climate, OLR1 necessarily balances the incoming ASR, although there is a great deal of fascinating atmosphere, ocean, and land phenomena that couple the two. Incoming radiant energy may be scattered and reflected by clouds and aerosols or absorbed in the atmosphere....
متن کاملGravity-driven postseismic deformation following the Mw 6.3 2009 L'Aquila (Italy) earthquake.
The present work focuses on the postseismic deformation observed in the region of L'Aquila (central Italy) following the Mw 6.3 earthquake that occurred on April 6, 2009. A new, 16-month-long dataset of COSMO-SkyMed SAR images was analysed using the Persistent Scatterer Pairs interferometric technique. The analysis revealed the existence of postseismic ground subsidence in the mountainous rocky...
