Juniper Lee shakes Orchid Bay's barrier
Decided to try and start calcing, starting the practice with what I think is an easy one. Juniper, after finding out she can't leave the city, is so angry and sad that she starts punching the barrier around the city, shaking it with each blow.
I'll be assuming she shook the whole thing cuz we don't see an end to the quakes, she just affects the whole screen. Orchid Bay is based on San Francisco, which is 121.4 km², so the radius we'll deal with is 60.7; and as for the magnitude, according to this neat chart, the magnitudes I'll use are from 2 to 3.5 since, though the earthquakes are clearly visible, there's not enough info to say they did any significant effect to something other than June's feelings.
Formula for artificial earthquakes: (if 60 < radius < 700) mag + 1.1644 + 0.0048 * r = scale.
Mag 2: 3.45576.
Mag 2.5: 3.95576.
Mag 3: 4.45576.
Mag 3.5: 4.95576.
Formula for joules: 10^1.5 * scale + 4.8 = j.
Mag 2: 9.630e9 j = 2.301 t.
Mag 2.5: 5.415e10 j = 12.942 t.
Mag 3: 3.045e11 j = 72.777 t.
Mag 3.5: 1.712e12 j = 409.177 t.
