Red Crescent volunteers in northern Iraq and Iran are providing urgent search and rescue and first aid to victims of the devastating 7.3 magnitude earthquake that shook the … The individual video images were rectified with a direct linear transformation (DLT) assuming a planar water surface at the level. Out of a large amount of data collected in the field, we are unveiling here the sand dunes’ erosion and the correlated sandy deposits. the boundary between the Indian and Arabian plates. A l'époque 2004 il été premier Ministre et Aujourd'hui il est President de la Republique au Sri-Lanka !! An assessment of the boulder movements indicates that the tsunami run-up had minimum velocities of 4.0–4.5 m s−1. The southwestern monsoon forces, inhabitants to vacate the settlements along the south coast and move inland or to the north, shore for a couple of months. The measured data was corrected for the tide level upon tsunami arrival, based on, ) were used. on Socotra occurred at the end of the Miocene Epoch (9-6 Ma BP). Le 26 décembre 2004, un grand tremblement de terre sous l’Océan indien provoquait de terribles tsunamis.

The tsunami of 26th December 2004 severely affected Banda Aceh along the North tip of Sumatra (Indonesia) at a distance of 250 km from the epicenter of the magnitude 9.0 earthquake. towards the open sea. Hence the MR not only affects the amplitude of the tsunamis but also comparable to those reported to the north in Oman (Okal et al. Privacy Policy. 2005 "Hvor små vi er" Giv Til Asien Poul Krebs & Remee: A charity single performed by Danish artists (singers, actors and musicians) under the name Giv Til Asien (translated as Give to Asia). We present a report from the work of the International Tsunami Survey Team in Oman in the aftermath of the 2004 Sumatra tsunami. Sixteen measurements were made; principally run-up values obtained from debris. The sizes ranged from fine sand to boulders, with medium sand and coarse sand being dominant. (2002) and Bardet et al. Les leçons apprises lors de la gestion de cette crise sans précédent marquent encore aujourd’hui les interventions de crise. The tide level prediction, rafted boat and debris in the background); (, in the low vegetation along the wadi delta plain. The distance of the sediment deposit area from the coast was 40 %–90 % of the distance of the inundation caused by the tsunami. Personne ne se souciait des enfants, alors que les besoins étaient énormes. All sediment samples had a well sorted distribution. ridge system is seen to change after crossing the MR towards the southeast direction for The motion of the camera during the recordings was determined. We suggest that the waves must have been triggered by a submarine slide on the Makran margin. Other estimates of the seismic moment, given in Figure 2, range from 1.2 to 4.9 × 1028 dyn-cm. Déjà présente sur place, Terre des hommes a pu très rapidement déployer des interventions d’urgence après le tsunami. heights rapidly decayed to 1–3 m in Oman as shown in Fig. Aujourd'hui, on n'utilise que l'échelle de Richter. The principal and, only city is Hadiboh with an estimated population of 43,000 in 2004 on the central north, shore of Socotra. watermarks, and eyewitness reports. Maximum run-up heights were typically on the order of 2–6m. run-up in 12 coastal settlements; four on the south coast: Shazhor, Mahfarhan, Abadhar. eastern and western MSZ are considered. A tsunami arrival, during high tide could have increased the run-up heights by up to 2, The deployment of the survey team to Socotra, almost 2, catastrophic event led to the recovery of important data on the characteristics of the, tsunami effects and inundation on Socotra in the tsunami far field. The measured tsunami flow velocities were within the range of 2 to 5 m/s. epicenter of the Magnitude 9.0 earthquake. 2006a, b), Oman (Okal et al. Abd Al-Kuri and. Earthquake Spectra. damaged coastal communities in countries along the Indian Ocean, including Indonesia, Thailand, Sri Lanka, India, Maldives, and Somalia (Synolakis and Kong, human lives, the tsunami also destroyed livelihoods, traumatized whole populations, and. Quel paradis de bonheur !! ), three smaller islands known collectively as ‘, Abd Al-Kuri, Samha, Darsa—and other uninhabitable rock outcrops. The eyewitnesses reported: an initial rise late morning between 11:00 and 12:00, approaching from the east with the second wave being the highest; the waves were, described as a gradual rise like an extraordinary high and fast tide; nobody was killed in. Most of the victims were reported along the low-lying Xaafuun peninsula. The survey also allowed the compilation of previously unreported data concerning the effects of the 2004 Sumatra–Andaman tsunami. Maximum heights for run-up unaffected by splash on nearby cliffs were found typically on the order of 1 to 3 meters, with a maximum of 3.3 m on beaches West of Salalah. We summarize findings and observations from the field surveys conducted in the aftermath of the 26 December 2004 tsunami. Hence, the tsunami hazard potential within the Arabian Sea is enigmatic. Figure 1A shows the epicenter and the extent of aftershocks over a 30-day window following the mainshock. The 2004 and tsunami caused a catastrophic amount of damage to the region of Aceh in Sumatra. Great changes in sea level occurred during the Quaternary Period, periodically exposing the surface of the Socotra platform. Each watermark was located using, 350 km south of the Arabian Peninsula (Terra-MODIS satellite image acquired 9 September 2006, NASA), measured tsunami run-up heights on a Landsat satellite image (NASA), a handheld global positioning system (GPS) receiver and photographed. Somalia's physical characteristics allowed a detailed assessment of the far-field impact of a tsunami in the main propagation direction. Le tableau ci-dessus montre cette correspondance. Show your support. Sand sheets were sporadic, highly variable, and highly influenced by topography. Terre des hommes (Tdh), alors active en Inde (Iles Andaman) ainsi qu’au Sri Lanka (districts de Batticaloa et d’Ampara), s’est aussitôt mobilisée pour venir en aide aux populations affectées. Given the. The international team members were on the ground in Yemen from 11 to 19 October 2006. Tsunami, impulse-waves and dam-break waves afflict humanity with casualties and damages. The Makran tsunami (B) strongly affects, Western India, the Maldives, and the Seychelles, as well as the Kerguelen Islands. Finally a cross-correlation based particle image velocimetry (PIV) analysis was applied to the rectified video images to determine instantaneous tsunami flow velocity fields. Most of the damage on Reunion was concentrated in harbors. La volonté internationale d’apporter une aide fut impressionnante, que cette aide soit officielle ou privée. The earthquake produced a tsunami that left an additional 24 people dead and 62 missing in the Camana area (INDEC, 2001).

Synolakis, Indian Ocean including of relevance for Socotra: (A) a repeat of the 1833 Southern Sumatra, earthquake, (B) simultaneously rupturing the faults of the 1851, 1945, and 1765 events in, the Makran (off Pakistan and Iran). (MSZ) will propagate through the MR system due to its proximity. Find stories, updates and expert opinion. Numerous eyewitness interviews were recorded on video. Make a donation; Media; Career; Contact; Podcasts The local impact of the 2004 Indian Ocean tsunami was only minor (Fritz and Borrero, 2006; Okal et al., 2006; Superconducting gravimeters are great instruments to monitor Earth's normal modes after major earthquakes, The 26 December 2004 tsunami severely affected Somalia, with some 300 deaths at a distance of 5 , 000 km from the epicenter of the magnitude 9.0 earthquake. In the near field of the epicenter, Sumatra was hardest hit by the, tsunami severely affected Sri Lanka across the Bay of Bengal at a distance of 1,600 km, from the epicenter or at a third of the distance between Sumatra and Somalia along the, Sumatra and Somalia were hit an hour after Sri Lanka at a distance of 2,500, In East Africa the tsunami impact focused on Somalia, some 5,000, impacted by tsunami runup heights of up to 9 m and inundation distances of up to 700 m, (Mudung region) and Xaafuun (Bari region), which forms part of the Puntland Province, near the Horn-of-Africa.
