introduction natural hazards as recurring phenomenon have always existed in human life and will in the future, too. nowadays natural hazards occur throughout the world, but their impacts have been increasing and are generally much greater in developing countries than in developed ones. earthquake is a kind of natural hazard that has the most damages for humankind. earthquakes pose inevitable ri...

Equipment used at nuclear power plants requires robust and reliable designs because in case of disaster, such as earthquake, small damage can turn into an unpredictable result. Control panel assembly structure used at nuclear power plants is important because of such reason. Seismic technology can be roughly categorized into analysis and experiment. The ideal way is testing the final product bu...

This paper describes the National Geodetic Survey (NGS) process for selecting and validating models for two recent earthquakes prior to their inclusion in the Horizontal Time Dependent Positioning software (HTDP v 2.9), the 28 September 2004 Parkfield, California earthquake with a magnitude of 6.0 and the 22 December 2003 San Simeon, California earthquake with a magnitude of 6.5 . The process o...

This paper summarises the impact of major earthquakes, 2010–2011, on Christchurch’s water supply network and what recovery measures have been applied, what worked well, what did not and why. A number of issues related to the open nature of the Christchurch water supply network were identified during earthquakes. It was difficult to manage large water supply pressure zones during the post-earthq...

The MJMA7.3 Kumamoto earthquake occurred on April 16, 2016, in the western part of Kyushu, at a depth of 12 km, on an active strike-slip fault. Here, we report on a relatively widespread activation of small remote earthquakes, which occurred as far as Hokkaido, detected by analyzing the continuous waveform data recorded at seismic stations all over Japan. Such relatively widespread remote seism...
