M 7.2 ميانمار زلزال - الرسومات زلزال سترى

This part 2 of our Myanmar March 24, 2011 reporting. انقر هنا للحصول 1 الجزء, giving the full story from when the earthquake was reported.

أوبديت شنومكس / شنومكس - شنومكس: شنومك أوتك: Teraphan Ornthammarath، دكتوراه و تقييم المخاطر الزلزالية والتخفيف عالم working at the Regional Integrated Multi Hazard Early Warning for Africa and Asia is describing the origin of the earthquake as follows :

ال خطأ الذي نشأ هذا الزلزال هو خطأ ما نام منشؤها من لاوس إلى ميانمار.
وقد وصفت في Lacassin وآخرون. (1998) أن هذا خطأ وضع علامة الأحفوري من تعويض خطأ في نهر ميكونغ (20.80N، 100.45E).
لم يكن هناك زلزال كبير منذ 1912 من هذا الخطأ.

Below a number of very good graphics from the Chinese Earthquake Authority.
They are showing very well the extension of the shaking, the faulting zones and the kind of earthquake it was.

الـ map below shows the area of shaking. Dark red means a destructive or violent shaking.
The dark orange color is a severe shaking (MMI VIII)
The green means a moderate shaking.
Please note the the the extend of damage is not only related to the Magnitude. The composition on the geologic layers is also very important. A proof of this, is that the yellow and green colors in Thailand are relatively undamaged. The weak green shaking at the Chinese part of the border was however very damaging with more than 5,000 houses damaged.

الـ picture below gives a very good overview of the mapped Fault lines in the area. The epicenter of the 7.2 earthquake from March 24 is indicated with the blue star, just next to the fault line. The green bullets are cities (greater size = bigger city).
The white part of the map is Chinese territory. The purple fault lines going from the North-West to the South-East in China are responsible for the Yunnan earthquakes from January 2, 2011 (major damage) and the Yunnan deadly earthquake from March 10, 2011 (killing 25 people and making (again) major damage).
النتيجة : The total area is very unstable at the moment.

الـ picture below shows the kind of earthquake it was. Apparently this was a strike-Slip fault.
Strike-slip fault = A fault whose relative displacement is purely horizontal.
Strike-Slip faulting is always very dangerous, even at some lower magnitudes.
