The earthquake of magnitude M-w = 8.3 that occurred on 24 May 2013 in the Sea of Okhotsk was the most powerful earthquake in the region. Fortunately, the generated tsunami was small because of the deep focal depth (609 km) and was only detected by the nearest Deep-ocean Assessment and Reporting of Tsunamis (DART) buoy records. However, the event highlighted the fact that any earthquakes with similar magnitudes at shallower focal depths would have caused considerable tsunamis. In order to evaluate the effects of possible tsunamis in the Sea of Okhotsk, we simulated water displacements due to the 24 May 2013 event and compared the results with the measurements. Moreover, the simulations were extended using different shallower focal depths. In simulations we calculated the coastal amplifications and possible heights of the tsunami waves along the coast of the Sea of Okhotsk.

Real-time experimental forecast of the Peruvian tsunami of August 2007 for US coastlines Wei, Yong; Bernard, Eddie N.; Tang, Liujuan; Weiss, Robert; Titov, Vasily V.; Moore, Christopher; Spillane, Michael; Hopkins, Mike; Kanoğlu, Utku (American Geophysical Union (AGU), 2008-02-27) At 23: 41 UTC on 15 August 2007, an offshore earthquake of magnitude 8.0 severely damaged central Peru and generated a tsunami. Severe shaking by the earthquake collapsed buildings throughout the region and caused 514 fatalities. The tsunami resulted in three casualties and a representative maximum runup height of similar to 7 m in the near field. The first real-time tsunami data available came from a deep-ocean tsunami detection buoy within 1 hour of tsunami generation. These tsunami data were used to prod...
Probabilistic earthquake hazard assessment for Ankara and its environs Ozmen, Bulent; Başbuğ Erkan, Berna Burçak (The Scientific and Technological Research Council of Turkey, 2014-01-01) The capital and the second largest city of Turkey, Ankara, is generally considered to be safe in terms of seismic activities and earthquake hazard. However, recent studies and earthquakes experienced in the region showed that Ankara is not indeed seismically safe. As the number of studies on Ankara's seismic hazard increases, the number of scientists who claim that the earthquake hazard in Ankara is higher than expected also increases. However, to date no detailed analysis has been undertaken as to the eart...
Source process of the 3 November 2002 Denali fault earthquake (central Alaska) from teleseismic observations Özacar, Atilla Arda; Christensen, DH (American Geophysical Union (AGU), 2003-06-25) [1] The November 3, 2002 Denali fault earthquake, which is the largest inland event ever recorded in central Alaska, occurred along an arcuate segment of the right-lateral strike-slip Denali fault. We use first-motion P wave polarities and inversions of teleseismic P waveforms for a fixed focal mechanism to constrain the rupture process. We find clear evidence for a substantial reverse component near the hypocenter at the beginning of the rupture. Twenty-five seconds later, rupture propagated unilaterally t...
The possibility of tsunami in the Sea of Okhotsk caused by deep-focus earthquakes Zaytsev, A. I.; Pelinovsky, E. N.; Kurkin, A. A.; Kostenko, I. S.; Yalçıner, Ahmet Cevdet (2016-03-01) The earthquake that occurred on May 24, 2013, in the basin of the Sea of Okhotsk with a magnitude of 8.3 was the strongest in this region. We have modeled a possible tsunami caused by such an earthquake. The simulations confirm that the wave heights were sufficiently small because the earthquake epicenter depth was 640 km. We analyze the oscillations of the DART buoys in the vicinity of the earthquake source and show that they were not associated with the tsunami waves. Analysis of the available pressure ga...
THE IMPACT OF TOPOGRAPHY ON ISOTOPES IN PRECIPITATION ACROSS THE CENTRAL ANATOLIAN PLATEAU (TURKEY) Schemmel, Fabian; Mikes, Tamas; Rojay, Fuat Bora; Mulch, Andreas (American Journal of Science (AJS), 2013-02-01) Paleoelevation reconstructions of mountain belts and orogenic plateaus based on stable isotope climate and precipitation records benefit greatly from present-day calibrations that relate the fractionation of hydrogen (delta D) and oxygen (delta O-18) isotopes in precipitation to orographic rainfall. Here, we establish a first-order template of delta D and delta O-18 of modern meteoric waters across the Central Anatolian Plateau (CAP) and its bordering Pontic and Taurus Mountains. We identify key regions in ...
