이번 지진을 보는 또 다른 시각

by mmgoon 2004. 12. 30.

이번에 큰 지진으로 인해 피해를 본 모든 분들에게 일단은 숙연~

지진이 일어난 진앙지는 총 4개의 지판이 모여있는 곳입니다. 

그러니까 인도판이 버마판을 밀고 이틈에 순다판과 버마판이 만나며서 아래쪽에 호주판과 상호작용을 하는 곳이죠. 

(자세한 설명은 아래를 참조하시시 -_-;;;;)



덕분에 별로 상관도 없는 베트남에도 여행자제령이 떨어지고 하는등 평소의 정부다운 반응을 보여주고 있습니다.

문제는....
연말이라 놀러다니시는 분들이 태국, 인도네시아 등등이 문제가 생기자 모두들 이곳으로 오신다는데 있습니다.
네네 연말이고 예산도 남으셨고, 일년동안 수고도 하셨을테죠 뭐....

하아- 내일도 여섯놈이나 온다고 연락을 받았습니다.
도데체 가정에 무슨 문제가 있어서 집구석에서 송구영신하지 못하고 12/31일에 베트남엘 온단 말인지. 

(모두들 아부지들에게 따뜻한 말한마디라도 합시다요. 불쌍한 김대리들을 살린다는 맘으로 말이져)

케익이나 하나사서 닭의 해를 자축하려던 계획은 물거품이 되었답니다.
아마도 모모처에서 춤추며 노래하는 예쁜 모습을 보이고 있을겁니다요.
이번 지진과 해일이 베트남에 보여준 피해현황입니다요.
흑흑-

The devastating megathrust earthquake of December 26, 2004, occurred on the interface of the India and Burma plates and was caused by the release of stresses that develop as the India plate subducts beneath the overriding Burma plate. The India plate begins its descent into the mantle at the Sunda trench, which lies to the west of the earthquake's epicenter. The trench is the surface expression of the plate interface between the Australia and India plates, situated to the southwest of the trench, and the Burma and Sunda plates, situated to the northeast.
In the region of the earthquake, the India plate moves toward the northeast at a rate of about 6 cm/year relative to the Burma plate. This results in oblique convergence at the Sunda trench. The oblique motion is partitioned into thrust-faulting, which occurs on the plate-interface and which involves slip directed perpendicular to the trench, and strike-slip faulting, which occurs several hundred kilometers to the east of the trench and involves slip directed parallel to the trench. The December 26 earthquake occurred as the result of thrust-faulting.
Preliminary locations of larger aftershocks following the megathrust earthquake show that approximately 1200 km of the plate boundary slipped as a result of the earthquake. By comparison with other large megathrust earthquakes, the width of the causative fault-rupture was likely over one-hundred km. From the size of the earthquake, it is likely that the average displacement on the fault plane was about fifteen meters. The sea floor overlying the thrust fault would have been uplifted by several meters as a result of the earthquake. The above estimates of fault-dimensions and displacement will be refined in the near future as the result of detailed analyses of the earthquake waves.
The world's largest recorded earthquakes have all been megathrust events, occurring where one tectonic plate subducts beneath another. These include:
the magnitude 9.5 1960 Chile earthquake, the magnitude 9.2 1964 Prince William Sound, Alaska, earthquake, the magnitude 9.1 1957 Andreanof Islands, Alaska, earthquake, and the magnitude 9.0 1952 Kamchatka earthquake. As with the recent event, megathrust earthquakes often generate large tsunamis that cause damage over a much wider area than is directly affected by ground shaking near the earthquake's rupture.
