Starting about thirty years ago, new ideas in nonlinear dynamics, particularly fractals and scaling, provoked an explosive growth of research both in modeling and in experimentally characterizing geosystems over wide ranges of scale. In this review we focus on scaling advances in solid earth geophysics including the topography. To reduce the review to manageable proportions, we restrict our att...

The subsidence of an aging seafl oor starts to slow down at ∼70 m.y. old with respect to that expected from simple half-space cooling, and this phenomenon has long been known as seafl oor fl attening. The fl attening signal remains even after removal of the infl uence of the emplacement of hotspot islands and oceanic plateaus. The combination of small-scale convection and radiogenic heating has...

Measurements from the Near Earth Asteroid Rendezvous (NEAR)-Shoemaker Laser Rangefinder (NLR) indicate that asteroid 433 Eros is a consolidated body with a complex shape dominated by collisions. The offset between the asteroid's center of mass and center of figure indicates a small deviation from a homogeneous internal structure that is most simply explained by variations in mechanical structur...

In 2007, the National Research Council (NRC) completed its first decadal survey for Earth science at the request of NASA, NOAA, and USGS.[1] The Lidar Surface Topography (LIST) mission is one of fifteen missions recommended by NRC, whose primary objectives are to map global topography and vegetation structure at 5 m spatial resolution, and to acquire global surface height mapping within a few y...

Introduction: Earth and Venus have many similar features, yet their tectonic histories are quite different. Like the Earth, Venus has a global rift system, which has been cited as evidence of tectonic activity, despite the apparent lack of Earth-style plate tectonics. Both systems are marked by large ridges, usually with central grabens. On Earth, the topography of the rifts can be modeled well...

On January 18, 2022, around 1 million kilometers from Earth, five times the distance Earth to Moon, a large asteroid passed without harm Earth. Theoretically, however, event of falling into causing tsunami, is possible since there are over 27,000 near-Earth asteroids [1], and Earth’s surface covered in 71 percent by water. We introduce novel graph-grammar-based framework for tsunami simulations...
