Shenhe Freeze Giant Wave[]

In this feat, Shenhe use her cryo to freeze the whole tsunami in a single attack.

Stone concrete height (1.625/215*324)=2.449m

Tsunami height (2.449/6*1,055)=430.616m
Now for the Tsunami length
The tsunami reached from the island with broken-down turrets to the south of the biggest island in Guyun Stone Forest.
Tsunami diameter (96,560.64/324*54)=16,093.44m
Then for the volume it looks to be the shape of a half cone (29,198,232,302.585/2)=14,599,116,151.292m3
Average seawater density is 1,024.5 kg/m3 (14,599,116,151.292*1,024.5)=14,956,794,496,998.654kg
Fusion the water into ice
14,956,794,496,998.654*334,000=4,995,569,361,997,550,436 joules
Cryo attacks change the water temperature
14,956,794,496,998.654*4,186*5=313,045,708,822,181,828.22 joules
4,995,569,361,997,550,436+313,045,708,822,181,828.22=5,308,615,070,819,732,264.22/4.184e18=1.269 Gigatons (Large Mountain Level High 7-A)
Azhdaha Shakes The Earth[]
In this feat, Zhongli stated that Azhdaha caused an earthquake that shook the earth.
The radius of the earthquake is the diameter of the planet since Azhdaha was on the surface of the planet during this feat.
Earth Radius in km: 12,756km
The magnitude should be 5 since the earthquake is stated to be heavy.
5+6.399+1.66*log((12,756/110)*((2*π)/360))=11.907
10^(1.5*11.907+4.8)/4.184e21=10.937 Teratons (Country Level 6-B)
Osial Shakes To Earth Core[]
It stated that when Osial was in his prime. He can make a roar that is powerful enough to cause earthquakes that shake the earth's to the core along with making tidal waves.
Osial was shaking the earth while on the surface of the earth making the earthquake radius 6,378km.
The magnitude should be 6 since Osial earthquake was making tidal waves.
6+6.399+1.66*log((6,378/110)*((2*π)/360))=12.408
10^(1.5*12.408+4.8)/4.184e21=61.717 Teratons (Country Level 6-B)
Lisa Creates Dark Clouds[]
This feat states and even shows that Lisa can create dark nimbostratus clouds that cover the entire sky
The horizon can reach over 4.8km (72,382,294.739m2), Average thickness of the nimbostratus is 3km and average sea-level height is 1,828.5m.
Calculator for the cloud mass (191,412,414,761.147kg)
The dark clouds speed
The small bits of cloud began to appear at 1.11 seconds, and by 1.25 seconds, the sky was completely covered. (0.14 seconds)
The distance of the dark clouds reach over the horizon which is 4.7km
4,800/0.14=34,285.714m/s
1/12*191,412,414,761.147*34,285.714^2/4.184e18=4.481 Gigatons (Island Level 6-C)
