At 14:46 on March 11, 2011 (local time), a large earthquake of magnitude Mw 9.0 took place, generating tsunami that caused severe damage to the east coast Japan. To comprehensively record trace heights and impacts along coastal region, Tohoku Earthquake Tsunami Joint Survey Group was organized immediately after event. As part this group, authors conducted field survey in Miyagi Fukushima Prefectures. The surveyed area can be divided into 2 parts from point view its geographical features:...
Abstract The authors have examined the characteristics of Typhoon Haiyan (Yolanda), which made landfall on coast Philippines November 2013, generating a substantial storm surge. In order to better understand surge phenomenon, its nature and severity were analysed by means numerical simulation field survey. Unlike most other tropical cyclones that weaken before they hit land, struck Leyte Island at near peak strength, with maximum sustained wind speeds 160 knots, strongest in recorded history...
On 11 March 2011, an exceptionally large tsunami event was triggered by a massive earthquake offshore, the northeast coast of Japan, which affected coastal infrastructure such as seawalls, dikes and breakwaters in Tohoku region. Such built to protect against Level 1 tsunamis that previously hit region, but not for events significant 2011 tsunami, categorized 2 [Shibayama, T., Esteban, M., Nistor, I., Takagi, H., Thao, N. D., Matsumaru, R., Mikami, Aranguiz, Jayaratne, R. & Ohira, K. [2013]...
This study presents the results of an experimental research program dealing with spatial debris motion on a horizontal apron depicting typical harbor wharf. Accordingly, scaled-down 6.1-m (20-ft) shipping containers were equipped novel yet nonintrusive real-time tracking system and sensors. The instrumentation allowed for spatiotemporal specimens moving across while entrained by incoming tsunami-like broken bore. proved its capabilities accuracy; this was particularly challenging since first...
A field survey team went to Palu City, Indonesia in the aftermath of September 28th, 2018 earthquake and tsunami investigate its effects on local infrastructure buildings. The study focused coast Bay, where a wave between approximately 2 7 m high impacted community as result several complex source mechanisms. following outlines results, loading caused by debris entrained within inundating flow. Damage timber buildings along was widespread, though reinforced concrete structures for most part...
The September 28 2018 Palu tsunami surprised the scientific community, as neither earthquake magnitude nor its strike-slip mechanism were deemed capable of producing wave heights that observed. However, recent research has shown generated several landslides inside bay. authors conducted a post-disaster field survey area affected to collect spatial data on inundation heights, nearshore and bay bathymetry, carried out eyewitness interviews testimonies event. In addition, numerical simulations...
Category 5 Typhoon Haiyan (known as Yolanda in the Philippines) made landfall Philippines on 8th November 2013 at almost peak of its power, devastating islands Leyte and Samar, amongst other places.The present paper analyses degree awareness preparedness Samar against storm surges prior to arrival typhoon Haiyan.The analysis was based field surveys interviewed with a variety local residents officials conducted during months after event.One key problems identified interviews how people were...
Category 5 Typhoon Haiyan was one of the strongest typhoons to hit Philippines in modern times, and introduced term "storm surge" vocabulary many local residents, who had not heard about such phenomena prior this event. The storm surge manifested itself on 8th November 2013 as made landfall, devastating large areas islands Leyte Samar. To attempt gain an understanding level awareness that residents surges authors conducted structured questionnaires (n = 172) focus group interviews with...
Typhoon Haiyan (Yolanda) struck the islands of Leyte and Samar, central part Philippines, on 8 November 2013, bringing large-scale devastation to coastal areas due high winds large storm surge waves associated with it. In order obtain distribution heights damage covering wide stretch affected coastline, authors carried out a series field surveys in aftermath typhoon (in December May 2014, October 2014). present paper, detailed results these summarized characteristics main causes damage,...
Abstract. Thin coastal dykes typically found in developing countries may suddenly collapse due to rapid land subsidence, material ageing, sea-level rise, high wave attack, earthquakes, landslides, or a collision with vessels. Such failure could trigger dam-break tsunami-type flooding, “dyke-break-induced tsunami”, possibility which has so far been overlooked the field of disaster science and management. To analyse potential consequences one such flooding event caused by dyke failure,...
Debris loads during flood events have been well-documented by forensic engineering field surveys of affected communities. Research has primarily focused on debris impact loading and less emphasis placed into quantifying the effects associated with damming, which occurs when solid objects accumulate at front structures. The formation dam shown to results in increased drag forces, backwater rise, flow accelerations can influence stability structure. This study examined a steady-state...
The design of breakwater armor units against tsunami attacks has received little attention in the past because comparative low frequency these events and rarity structures designed specifically to withstand them. However, field surveys recent events, such as 2011 Tohoku Earthquake Tsunami Indian Ocean 2004, have shown flaws protection structures. During extreme many breakwaters suffered partial or catastrophic damage. Although it is be expected that most normal fail high-order practicing...
