Wall Level To Large Island level reference

## Introduction

**What will you find here?** this Page is made for the tiers "Wall Level" All the way up to "Large Island Level". A variety of different things will be found within this page as well as the sources for each one at the very bottom. Each of these tiers was done individually so make sure to read the description for each tier if you're wondering how we came to the conclusions we did. This wiki gives TNT value within work but highlights the usage of "Joules" as the standard unit of measurement for most numbers even within the "Low tiers" like wall level. TNT standards are used within most wikis and we don't exclude them. If you are better with TNT values Here Is a link to a standard TNT to Joule converter. The beginning part from Wall Level to Multi-City Block Level were taken from a fanverse thread and i claim no originality from it however everything else that was done and shown was done here and all math is done by The Founder of the WIki

## The Math

### **Wall Level:**

At least 1 m^3 of stone-like material destroyed

- Destroying an actual wall.

- Blast area of at least 5 m^2

(5000 Joules to 2092000 Joules)

A 2 x 2 x .25 m brick wall would qualify as a good minimum.

### **Small Building Level**

- At least 25 m^3 of stone-like material destroyed

- Destroyed an actual small building

- Blast area of at least 49 m^2 (Approx. 8 m blast diameter)

(2092000 Joules to 1.046x10^9 Joules)

### **Building Level**

- At least 200 m^3 of stone-like material destroyed

- Destroyed an actual building

- Blast area of at least 400 m^2 (Approx. 23 m blast diameter)

(1.406x10^9 Joules to 8.368x10^9 Joules)

A 20 x 20 m building would be a good minimum here.

### **High-Rise level**

- At least 1,250 m^3 of stone-like material destroyed

- Destroyed a large building (5 stories high or more)

- Blast Area of at least 2,500 m^2 (Approx. 56 m blast diameter)

(8.368x10^9 Joules to 4.602x10^10 Joules)

A 50 x 50 m building would be a good minimum.

### **City Block Level**

- At least 22,680 m^3 of stone-like material destroyed

- Destroyed an entire city block

- Blast area of at least 21,920 m^2 (Approx. 167 m blast diameter)

(4.602x10^10 Joules to 1.206749x10^11 Joules)

The average Manhattan city block is what we go by. It's 274 x 80 m

### **Multi-Block Level**

At least double any of the Results of "City Block Level"

(1.206749x10^11 Joules to 3.2015038x10^12 Joules)

### **Small Town Level**

The Vatican City, And the Pentagon are the sizes of smaller town off radius we can see the yield would be as follow

Air blast radius (near-total fatalities) Yield: Y = ((x/0.28)^3)/1000 with Y in megatons of TNT and x the radius in km.

Y = ((0.45317664/0.28)^3)/1000 = 0.0042396348200000001 megatons or **1.773863208688x10^13 Joules**

### **Town Level**

- At least 3,050,000 m^3 of stone-like material fragmented

- At least 3,942 m^3 of stone-like material melted

- At least 796 m^3 of stone-like material vaporized

- Destroyed an actual town completely (At least 0.6 Km in diameter)

- Blast area of at least 785,000 m^2

- At least a 5.8 Kiloton yield

Air blast radius (near-total fatalities) Yield: Y = ((x/0.28)^3)/1000 with Y in megatons of TNT and x the radius in km.

((0.85/0.28)^3)/1000 = 0.0279758108599999986 Megatons of TNT or **1.1705079263824x10^14 Joules**

### **Large Town Level**

The Spartly islands are very small islands in the south China sea. ranging from 1-3.2 km we can see the Yield from equation as follows:

Air blast radius (near-total fatalities) Yield: Y = ((x/0.28)^3)/1000 with Y in megatons of TNT and x the radius in km.

Y = ((1.0028291/0.28)^3)/1000 = 0.045941660619999998 Megatons of TNT or 1.9221990803408x10^14 Joules

Y = ((3.172920/0.28)^3)/1000 = 1.455134952389999903 Megatons of TNT or **6.08828464079980x10^15 Joules**

### **Small City Level**

The republic of Naru or the island of Naru is a small area which is called one of the 3 "Phosphate rocks" in the pacific although called large its minuscule being 5.243km for our radius here

Air blast radius (near-total fatalities) Yield: Y = ((x/0.28)^3)/1000 with Y in megatons of TNT and x the radius in km.

((3.176/0.28)^3)/1000 = 1.45937662974 Megatons of TNT or 6.10603181883220x10^15 Joules

Y = ((4.243/0.28)^3)/1000 = 3.4797256244098946354 Megatons or **1.4559172012531x10^16 Joules**

### **City Level**

The average city radius that we will be using for this listed by yocombinator is 15 km for our radius

Air blast radius (near-total fatalities) Yield: Y = ((x/0.28)^3)/1000 with Y in megatons of TNT and x the radius in km.

Y = ((15/0.28)^3)/1000 = 153.74453352799952199 Megatons or **6.43267128281149958x10^17 Joules**

### **Mountain Level**

Based on the average angle of repose being 40 and assuming a uniform conical shape as well as the fact that they range between 3-5 miles high we get our average diameter of 67.502 km and a blast radius of 33.751km and for our low end we get a blast radius of 27.234km

Air blast radius (near-total fatalities) Yield: Y = ((x/0.28)^3)/1000 with Y in megatons of TNT and x the radius in km.

Y = ((27.234/0.28)^3)/1000 = 920.153336776 Megatons of TNT or 3.8499215610708x10^18 Joules

Y = ((33.751/0.28)^3)/1000 = 1751.4019981700048447 Megatons or **7.3278659603433x10^18 Joules**

### **Large Mountain**

Based off the same numbers that we got last time we can get the upper range of what the average Mountain would be and we can see that at the upper end they would be around 170 km as our diameter making our total blast radius 85 km and our low end is 55 km blast radius

Air blast radius (near-total fatalities) Yield: Y = ((x/0.28)^3)/1000 with Y in megatons of TNT and x the radius in km.

Y = ((55/0.28)^3)/1000 = 7579.03607872 Megatons of TNT or **3.1710686953364x10^19 Joules**

Y = ((85/0.28)^3)/1000 =27975.8108601 Megatons of TNT or 1.1705079263866x10^20 Joules

### **Island Level**

Islands that would be referenced here as our average size would be things like Jamaica Belgium Israel Or even Yellowstone larger areas of land like this would range between 125-190 km which means we can use this

Air blast radius (near-total fatalities) Yield: Y = ((x/0.28)^3)/1000 with Y in megatons of TNT and x the radius in km.

Y = ((125/0.28)^3)/1000 = 88972.5309767 Megatons of TNT or **3.7226106960651x10^20 Joules**

Y = ((190/0.28)^3)/1000 = 312454.446064 Megatons of TNT or 1.3073094023318x10^21 Joules

### **Large Island Level**

Large Islands are land masses that are larger than our previous "Island Level" By a large margin in total area this would be things like Austria, South Korea, North Korea Cuba and Great Britain. These areas would be access of around 210km as our blast radius up to around 350km

Air blast radius (near-total fatalities) Yield: Y = ((x/0.28)^3)/1000 with Y in megatons of TNT and x the radius in km.

Y = ((210/0.28)^3)/1000 = 421875 Megatons of TNT or 1.765125x10^21 Joules

Y = ((380/0.28)^3)/1000 = 1229956.26822 Megatons of TNT or **1.0458475218646x10^22 Joules**
