We present results from differential Global Positioning System (GPS) surveys of seven alignment arrays and four continuous GPS sites along the creeping segment of the San Andreas fault. Surveys of four alignment arrays from the central creeping segment yield 33to 36-year average minimum slip rates of 21–26 mm/yr. These rates are consistent with previous alignment array surveys spanning a 10-yea...

The high hillsides of the Tehran metropolis are prone to landslides due to the climatic conditions and the geological, geomorphologicalcharacteristics of the region. Therefore, it is vitally important that a landslide susceptibility map of the region be prepared. For thispurpose, thematic layers including landslide inventory, lithology, slope, aspect, curvature, distance to stream, distance to ...

The Earthquake of January 26, 2001 of magnitude 7.6 on Richter scale has resulted in more than 25,000 fatalities and wide spread damage in India and SouthEast lower part of Sindh, Pakistan. The Intensity of this earthquake was felt from severe to minor near the epicenter and areas within 400 km radius. It has been reported that severe damage has occurred to mid to high-rise buildings in the cit...

Distance relays are used to protect EHV and HV Transmission lines. Over the past decades many algorithms have emerged for digital distance relays. These are based on the calculation of the transmission line impedance from the relaying to fault points. In this paper a novel method for digital distance relaying is proposed. In the method the tracking procedure is implemented. The method uses the ...

A physical model of earthquake lights is proposed. It is suggested that the magnetic diffusion from the electric and magnetic fields source region is a dominant process, explaining rather high localization of the light flashes. A 3D numerical code allowing to take into account the arbitrary distribution of currents caused by ground motion, conductivity in the ground and at its surface, includin...

The tsunami source of the 2016 Fukushima Earthquake, which was generated by a normal faulting earthquake mech‐ anism, is estimated by inverting the tsunami waveforms that were recorded by seven tide gauge stations and two wave gauge stations along the north Pacific coast of Japan. Two fault models based on different available moment tensor solutions were employed, and their locations were const...
