Evidence for Recent Large Magnitude Explosive Eruptions at Damavand Volcano, Iran with Implications for Volcanic Hazards
Damavand is a large dormant stratovolcano in the Alborz Mountains of northern Iran located in one of the most populous provinces, which could be adversely affected by tephra fall from Damavand. The youngest known eruption is a lava flow on the western flanks with an age of 7.3 ka. The volcanic products are predominantly porphyritic trachyandesite. Three major young pumice deposits, named here a...
متن کاملRelation of major volcanic center concentration on venus to global tectonic patterns.
Global analysis of NASA Magellan image data indicates that a major concentration of volcanic centers covering approximately 40 percent of the surface of Venus occurs between the Beta, Atla, and Themis regiones. Associated with this enhanced concentration are geological characteristics commonly interpreted as rifting and mantle upwelling. Interconnected low plains in an annulus around this conce...
متن کاملThe surface of Venus
Venus is a planet that is similar to Earth in terms of some important planetary parameters (size, mass, position in the solar system, presence of atmosphere) and different in terms of other, equally important ones (absence of an intrinsic magnetic field, large atmospheric mass, carbon dioxide composition of the atmosphere, lack of water, very high surface pressure and temperature). The surface ...
متن کاملTellus Regio, Venus: Evidence of Tectonic Assembly of Tessera Terrain and Implications for Exploration
Introduction: Tellus Regio is a plateau-shaped highland in the northern hemisphere of Venus largely composed of tessera terrain characterized by complex deformation comprising at least two sets of intersecting ridges and grooves which contribute to high radar backscatter [1,2; Fig. 1]. Stratigraphic studies of tessera terrain occurrences establish that they are generally embayed by plains mater...
متن کاملPLANet: An Active Internetwork
We present PLANet: an active network architecture and implementation. In addition to a standard suite of Internet-like services, PLANet has two key programmability features: 1. all packets contain programs 2. router functionality may be extended dynamically Packet programs are written in our special purpose programming language PLAN, the Packet Language for Active Networks, while dynamic router...
