3D Visualization for Urban Earthquake Risk
Visualization is the graphical presentation of information, with the goal of improving the viewer’s understanding of the information contents. As today’s world is getting richer in information, visualization of the information is important for effective communication and decision making. In this study, generation of a 3D city model in CAD environment and its use in a spatial decision support sy...
متن کاملThe 2012 Sumatra great earthquake sequence
recorded (moment magnitudes Mw1⁄48.6 and 8.2). Broadband seismological observations of the Mw1⁄48.6 mainshock indicate a large centroid depth ( 30 km) and remarkable rupture complexity. Detailed study of the surface-wave directivity and moment rate functions clearly indicates the partition of the rupture into at least two distinct subevents. To account for these observations, we developed a pro...
متن کاملThe great Sumatra-Andaman earthquake of 26 December 2004.
The two largest earthquakes of the past 40 years ruptured a 1600-kilometer-long portion of the fault boundary between the Indo-Australian and southeastern Eurasian plates on 26 December 2004 [seismic moment magnitude (Mw) = 9.1 to 9.3] and 28 March 2005 (Mw = 8.6). The first event generated a tsunami that caused more than 283,000 deaths. Fault slip of up to 15 meters occurred near Banda Aceh, S...
متن کاملSeismological Aspects of the December 2004 Great Sumatra-Andaman Earthquake
The 2004 Great Sumatra-Andaman earthquake had an average source duration of about 500 sec. and a rupture length of 1 ,200–1,300 km. The seismic moment, M0, determined with a finite source model, was 6.5 1022 N-m, which corresponds to Mw=9.18. Allowing for the uncertainties in the current M0 determinations, Mw is in the range of 9.1 to 9.3. The tsunami magnitude Mt is 9.1, suggesting that the ov...
متن کاملMultiple CMT source analysis of the 2004 Sumatra earthquake
[1] While it is agreed that the great Sumatra earthquake of December 26, 2004 was among the largest earthquakes of the past century, there has been disagreement on how large it was, which part of the fault ruptured, and how the rupture took place. We present a centroid-moment-tensor (CMT) analysis of the earthquake in which multiple point sources are used in the inversion to mimic a propagating...
