You run the volcano observatory. Read the warning signs, call the evacuation at the right moment, and get out alive.

YOUR JOB: log every warning sign from the observatory, raise the town's alert level in time to evacuate it — then get yourself past the ridge to the safe zone.

📚 FIELD GUIDE
Three Kinds of Volcano
Shield
Runny, low-gas lava spreads far before it cools, building a broad, gently sloping dome.
Eruption style: quiet lava flows · e.g. Mauna Loa
Stratovolcano
Thick, gas-rich magma traps pressure. Alternating ash and lava layers build a steep cone — and violent, explosive eruptions. This is the one you are standing on.
Blobs of frothy lava are thrown into the air, cool in flight and pile up as loose cinders into a small, steep cone.
Eruption style: short bursts of ash & cinders · e.g. Parícutin
💡 The shape of a volcano tells you how it erupts. Steep sides mean sticky, gas-rich magma — and that magma is the dangerous kind, because gas cannot escape gently.
❓ HOW TO PLAY
You cannot control the volcano. That is the point.
Magma rises on its own schedule. Your job is to read it, warn the town, and know when to run. Three things are scored:
1
⚠️ LOG THE WARNING SIGNS
Precursors appear in the monitor feed: quake swarms, SO₂ spikes, a bulging summit. Hit LOG WARNING SIGN while one is live.
Your instruments only reach so far. Step outside the purple ring on the map and you go blind — but that ring sits deep inside the danger zone.
2
🏘 CALL THE EVACUATION
Raise the TOWN ALERT LEVEL. Higher levels empty the town faster, and a full evacuation takes minutes.
Panic early with no evidence and your credibility drains — then nobody moves when it actually matters. Wait too long and there is no time left.
3
🏃 SAVE YOURSELF
Tap the map (or use arrow keys) to move. Roads are roughly twice as fast as open ground.
The red zone grows as risk climbs. Inside it, ash and gas exposure builds — fill that bar and you collapse. The safe zone lies behind the ridge to the east.
The volcano will erupt. Every second you stay near the crater buys data and points — and costs you escape time. That trade is the whole game.
