Population dynamics of Capitella aff. teleta (Polychaeta, Capitellidae) in Gamo Lagoon, northeastern Japan, during a series of restoration works following the 2011 Great East Japan Earthquake and tsunami

Capitellid polychaete Capitella aff. The Capitella aff's population dynamics are reflected in this capitellid polychaete Capitella aff's demography. Following the 2011 Great East Japan Earthquake and tsunami, teleta were studied in Gamo Lagoon, northeast Japan, for the next two years from 2016, when a series of restoration projects were carried out. During the reconstruction of a flow-conducting levee, which blocked water flow and isolated the lagoon's inner portion, the daily maximum water level dropped from 2017 to 2018 in the lagoon. In Gamo Lagoon, C, C. Hence, the maximum water level had a huge effect on the C's maintenance. ' The lagoon's teleta population is located in the lagoon, and sufficiently high water levels enable planktonic larvae dispersion to help recover the population quickly, indicating that keeping the water area intact is crucial.

Analysis of Tsunami Flow Velocities during the March 2011 Tohoku, Japan, Tsunami

On the Pacific coast of Japan, the Tohoku, Japan, earthquake in March 2011 caused significant damage to many buildings, bridges, and lifelines. To determine the force acting on structures, it's necessary to determine the force acting on buildings must be determined by analyzing its effects on buildings, the tsunami flow rate, and the tsunami flow depth. On several websites, videos describing tsunami flows are also available. Ten cases of tsunami flow velocities and flow directions are investigated from videos by determining the movement distances of observed objects. The velocities from recorded videos were similar to those from recorded images at the same locations as the video images.

Estimation of Tsunami-Inundated Areas in Asahi City, Chiba Prefecture, after the 2011 Tohoku-Oki Earthquake

A tsunami was caused by the 2011 earthquake off the coast of Tohoku-oki, Japan's. The map of disaster relief volunteers and the satellite photos of the event revealed Tsunami-inundated areas in Asahi City in Asahi City. The authors compared the identified trouble areas with Asahi City's newly updated tsunami risk map. In addition, a numerical simulation of tsunami propagation was conducted, and the proportion of completely destroyed buildings to the total number of buildings, i. e. damage ratio, was calculated in terms of the estimated inundation depths.

Extraction of Tsunami-Flooded Areas and Damaged Buildings in the 2011 Tohoku-Oki Earthquake from TerraSAR-X Intensity Images

The Tohoku earthquake of 11 March 2011 caused large tsunamis and widespread destruction. Since the water surface generally shows little backscatter, flooded areas could be extracted by the difference of backscattering coefficients between the pre- and post-event photographs. The difference and correlation coefficients were determined within each building's outline. The damage estimates were compared to visual interpretation results, which showed that the overall reliability of the proposed method for flooded areas was 80%, and that for damaged buildings was 94%.

Overview of the 2011 Tohoku Earthquake Tsunami Damage and Its Relation to Coastal Protection along the Sanriku Coast

We examined three main areas from the Sanriku ria coast to determine the success of several types of tsunami protection schemes. To determine the success of various types of tsunami prevention schemes, we analyzed three key areas. For severe tsunami, which exceeds ten meters off the coast, offshore tsunami breakwaters and coastal forests are discussed. The survey findings and findings from numerical analysis point to the decrease of tsunami damage in Kamaishi Bay due to an offshore barrier.

The Effect of Situated Access on People with Disabilities: An Examination of Sheltering and Temporary Housing after the 2011 Japan Earthquake and Tsunami

The 11 March 2011 Tohoku-oki earthquake and tsunami, which devastated coastal communities in three Japanese prefectures, resulted in significant loss of life, property loss, and community chaos. Using interview and observation results point to situated access as a factor in how and when people with disabilities received funding and services. That is, the ability of evacuees to obtain and use information, material resources, or services was based both on the physical location of the individual or group within the geographical location, as well as the individual's socioeconomic status or family's social status or situation of the individual or group within the geographic area.

Reliability of Bridges under Tsunami Hazards: Emphasis on the 2011 Tohoku-Oki Earthquake

The probabilistic estimation of tsunami impacts on bridges and the assessment of potential tsunami risks are important issues, but they are still in the early stages of development. Empirical tsunami fragility curves based on the analysis of damage reports from previous tsunami disasters have been developed. Using the tsunami hazard and fragility curves, the likelihood of a Bridge failure can be estimated.

Economic Impacts of the 2011 Tohoku-Oki Earthquake and Tsunami

The first year after the 2011 Tohoku-oki earthquake, tsunami, and nuclear explosion, the highest natural disaster on record, has an estimated u00a516. 9 trillion in direct damage, with an estimated u00a516. 9 trillion in direct damages. Significant energy conservation has been achieved nationally because of reduced capacity for producing electricity. The results from using a loss estimation software showed promising compatibility with observed post-disaster economic growth.
