This study presents a plan for seismic monitoring of a region around a potential nuclear power plant. Seismic monitoring is needed to evaluate seismic risk. The International Atomic Energy Agency has set guidelines on seismic hazard evaluation and monitoring of such areas. According to these guidelines, we have made a plan for a local network of seismic stations to collect data for seismic sour...

Previous analysis of the magnetic spectrum of Mars showed only a crustal source field [1]. The observational spectrum was fairly well fitted by the spectrum expected from random dipolar sources scattered on a spherical shell about 46 ± 10 km below Mars’ 3389.5 km mean radius. This de-correlation depth overestimates the typical depth of extended magnetized structures, and so was judged closer to...

We present photometric observations and analysis of the second microlensing event detected towards the Small Magellanic Cloud (SMC), MACHO Alert 98-SMC-1. This event was detected early enough to allow intensive observation of the lightcurve. These observations revealed 98-SMC-1 to be the first caustic crossing, binary microlensing event towards the Magellanic Clouds to be discovered in progress...

The local earthquake events recorded north of Panjal thrust (=Main Central thrust) and Main Boundary Thrust (MBT) by the four broadband seismological observatories located at Jammu, Poonch, Doru and Bani in Jammu and Kashmir from January to May, 2012 have coda magnitudes ranging from 1.7 to 3.8 were used to compute source parameters namely; seismic moment, source radius, and stress drop. These ...

A deep spectrum taken with the Echelle Spectrograph and Imager (ESI) at the Keck II Telescope as part of the Lenses Structure and Dynamics (LSD) Survey reveals the redshifts of the extremely red source of the radio Einstein Ring in the gravitational lens system MG1549+305 (zs = 1.170 ± 0.001) and an intermediate redshift lensed spiral galaxy (zG2 = 0.604 ± 0.001). The source redshift allows us ...

RX J1856.5−3754, a bright soft X-ray source believed to be the nearest thermally emitting neutron star, has commanded and continues to command intense interest from X-ray missions. One of the main goals is to determine the radius of this neutron star. An integral part of the determination is an accurate parallax. Walter (2001) analyzed Hubble Space Telescope (HST ) data and derived a parallax, ...

In diesem Artikel wird die Entwicklung eines Informationssystems auf Basis von Open-Source-Komponenten vorgestellt, das die Darstellung des exakten Standortes eines Webseitenbetreibers einer aufgerufenen Webseite automatisiert. Aktuelle, im Web gängige Systeme gestatten die genaue Darstellung eines Ortes erst nach Eingabe der zugehörigen Adresse oder verwenden zur Bestimmung von Standortdaten G...

historical earthquakes play a notable role in engineering seismology. the historical kashan-sialk region, 3 km south of kashan, was surveyed in the viewpoint of historical earthquakes events. several devastating historical earthquakes, occurred in the bc time, identified based on archaeological studies and evidences gathered from field study. in this respect a variety of information, namely tim...

Detecting the disappearance of active leks is the most efficient way to determine large declines in greater sage-grouse (Centrocercus urophasianus) populations; thus, understanding factors that influence lek abandonment is critical. We evaluated factors that may have influenced the probability of sage-grouse lek abandonment in the Bighorn Basin (BHB) of north-central Wyoming from 1980 to 2009. ...

We report the discovery of two concentric partial Einstein rings around the gravitational lens SDSSJ0946+1006, as part of the Sloan Lens ACS Survey. The main lens is at redshift zl = 0.222, while the inner ring (1) is at redshift zs1 = 0.609 and Einstein radius REin1 = 1.43 ± 0.01. The wider image separation (REin2 = 2.07±0.02′′) of the outer ring (2) implies that it is at higher redshift than ...
