On September 28th, 2018, a powerful earthquake (M-w 7.5) struck the Island of Sulawesi in Indonesia. The earthquake was followed by a destructive and deadly tsunami that hit the Bay of Palu. A UNESCO international tsunami survey team responded to the disaster and surveyed 125km of coastline along the Palu Bay up to the earthquake epicentre region. The team performed 78 tsunami runup and inundation height measurements throughout the surveyed coastline. Measured values reached 9.1m for the runup height and 8.7m for the inundation height, both at Benteng village. The survey team also identified ten large coastal sectors that collapsed into the sea of Palu Bay after the earthquake. The distribution of the measured tsunami data within Palu Bay exhibits a clear localised impact suggesting the contribution of secondary non-seismic local sources to the generation of the tsunami. Findings of the field reconnaissance are discussed to provide an insight into the remaining debated source of the Palu tsunami.

The 25 march 2020 tsunami at the Kuril islands: Analysis and numerical simulation Zaytsev, Andrey; Dogan, Gozde Guney; Dolgikh, Grigory; Dolgikh, Stanislav; Yalçıner, Ahmet Cevdet; Pelinovsky, Efim (2020-11-01) A strong earthquake with a magnitude of 7.5 occurred near the island of Paramushir (KurilIslands) on 25 March 2020. It caused a weak tsunami in Kamchatka and the Kuril Islands.Earthquake and tsunami data from three DART buoys are discussed and compared withnumerical simulations. It is shown that the calculated and measured tsunami characteristics onthe DART buoys is in very good agreement. There are also data on the recording of thisearthquake by a laser strain-meter installed in the Sea of Japan at Shults ...
The tsunami of August 17, 1999 in Izmit Bay, Turkey Altinok, Y; Tinti, S; Alpar, B; Yalçıner, Ahmet Cevdet; Ersoy, S; Bortolucci, E; Armigliato, A (2001-01-01) The Kocaeli 1999 Earthquake with an Mw = 7.4 caused major hazards throughout the NW of Turkey from Tekirdag to Bolu. Historical data indicates that some of the earthquakes around Izmit Bay have caused tsunamis. In this study, tsunami research for the Kocaeli 1999 Earthquake has been made also taking into consideration historical data. In this research more than about 70 data at 35 localities have been used to determine the tsunami evidences in the bay. Coastal observations indicated runups which were rangin...
THE JULY 20, 2017 BODRUM/KOS EARTHQUAKE AND TSUNAMI: FIELD SURVEYS, LESSONS and MODELING Yalçıner, Ahmet Cevdet; Papadopoulos, Gerassimos A; Doğan, Gözde Güney; Güler, Hasan Gökhan; Özer Sözdinler, Ceren; Ulutaş, Ergin; Arıkawa, Taro; Süzen, Mehmet Lütfi; Kanoğlu, Utku; Güler, Işıkhan (null; 2018-08-04) A magnitude (Mw) 6.6 earthquake occurred on July 20, 2017 (22:31 UTC) in between Bodrum, Turkey and Kos Island, Greece. Field surveys are conducted in the region (Yalciner et al., 2017) including southern and northern coastlines of Bodrum peninsula, Karaada, Akyaka town and Kos Island. A tide gauge located in Bodrum main port recorded the tsunami. The main objectives of these field surveys are to document tsunami effects along the coast, to obtain the available data on the wave height and inundation extent,...
The 30 October 2020 Aegean Sea Tsunami: Post-Event Field Survey Along Turkish Coast Dogan, Gozde Guney; Yalçıner, Ahmet Cevdet; YÜKSEL, Yalçın; ULUTAŞ, ERGİN; Polat, Orhan; Güler, Işıkhan; ŞAHİN, Cihan; Tarih, Ahmet; Kanoğlu, Utku (2021-03-01) On 30 October 2020, a strong normal-faulting earthquake struck Samos Island in Greece and Izmir Province in Turkey, both in the eastern Aegean Sea. The earthquake generated a tsunami that hit the coasts of Samos Island, Greece and Izmir, Turkey. National teams performed two post-tsunami field surveys on 31 October to 1 November 2020, and 4-6 November 2020, along the Turkish coastline; while the former was a quick survey on the days following the tsunami, the latter involved more detailed measurement and inv...
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...
