Blocked Supervolcano

After further study of the extreme seismic tension on …, we have discovered that a colossal supervolcano has become blocked by a partial upper cone collapse. Vast reserves of magma have filled all available underground chambers and are exerting immense upward pressure against the blockage in the main vent. The collapsed material is currently holding the magma in place, but it is impossible to predict how long this delicate equilibrium will last. The trapped molten rock is exceptionally rich in rare metals and complex mineral compounds. … believes we can harvest these resources safely by facilitating a controlled eruption.

The command below will trigger the "Blocked Supervolcano" event in Stellaris:

When this event fires, you can choose between these 2 options:

• Unblock the vent.
  • Start special project: Controlled Eruption
• Put the geothermal activity to good use.
  • Energy Credits: +None to None
