It's very serious. Mianyang is the hardest hit area. Of the 8 national key cultural relics protection units in Mianyang, 5 were seriously damaged, 31 provincial cultural protection units and 24 were damaged.

the epicenter intensity of the Wenchuan earthquake is as high as 11 degrees, and the area of the 11-degree area of the Wenchuan earthquake is about 3144 square kilometers, which is long and narrow in the northeast, reaching Qingchuan County in Sichuan Province in the northeast and Wenchuan in the southwest.

the 9-degree zone covers an area of about 7,738 square kilometers, which is also long and narrow in the northeast direction, with the northeast end reaching the junction of Wudu District in Longnan City, Gansu Province and ningqiang county City in Shaanxi Province, and the southwest end reaching Wenchuan County.

Wenchuan earthquake is more destructive than Tangshan earthquake for the following reasons:

First, it can be seen from the magnitude that Wenchuan earthquake is slightly stronger. The internationally recognized Tangshan earthquake is 7.8, and the Wenchuan earthquake is 8.1.

Secondly, from the perspective of geo-mechanism fault dislocation, the Tangshan earthquake was extensional, and the hanging wall fell down. Wenchuan earthquake Wenchuan earthquake is a compressive fracture, and the upper wall is rising, which has a greater impact than Tangshan earthquake.

Third, the fault dislocation time of Tangshan earthquake is 12.9 seconds, and that of Wenchuan earthquake is 22.2 seconds. The longer the dislocation time, the longer people feel the strong earthquake, which means that the swing duration of buildings in Wenchuan earthquake is stronger than that in Tangshan earthquake.

fourthly, Wenchuan earthquake affected an area larger than Tangshan earthquake. This is mainly due to the fault dislocation, which is in the northeast direction, which means that the northeast direction of Wenchuan is greatly affected, but the situation in its west will be better.
