CHATQUAKE ARCADE / OBS PREVIEW
Let the paper roll. The first eruption arrives around 35 seconds.
Did you feel it?
Viewers type
!felt
to report the shaking. Watch the intensity climb from I to X.
Keep the good parts
Export your quake catalog as CSV, JSON, or YouTube chapters. Give your editor a head start.
On stream in three steps.
1. Enter your channel
Copy the overlay URL above. Chatquake listens anonymously to public Twitch chat.

Small chat. Big energy.
Magnitude is relative to your channel's baseline. Five viewers can make the earth move just as much as fifty thousand.
ratio = mean rate over 5 s / mean rate over 180 s
M = 1 + 2 log10(peak ratio) + 0.6 log10(1 + unique chatters)
After a 30-second warmup, a ratio of 3 with at least four messages starts a quake. The long-term baseline freezes during shaking. Magnitude rounds to one decimal, between 1.0 and 9.9.
Shaking ends after four seconds below the trigger-off ratio or 30% of peak activity. Every quake ends within 90 seconds.
n(t) = K / (t + 30)^1.1
K = 0.002 × 10^(0.5 × (M - 1))
P(at least one aftershock) = 1 - exp(-∫ n(t) dt)
The forecast borrows the modified Omori law and a playful Bath's-law-inspired scaling. It is entertainment, not a calibrated prediction.
Your chat, your browser.
Anonymous and read-only. No OAuth, tokens, or server-side chat
storage. Your catalog lives in this browser, including up to three
short message samples per quake. Add

Chatquake cannot post messages or create Twitch stream markers. CSV and chapters are your export path. OBS and your browser have separate storage, so keep the catalog page running while you stream.
