MICRO-NODE 01
The VEI 8 Threshold
- Highest Explosivity Index
- 1,000+ cubic km ejecta
- Catastrophic global impact
- Extremely rare occurrence
MICRO-NODE 02
Massive Magma Chambers
- Colossal subterranean volume
- Accumulates over millennia
- Melts surrounding crust
- Buoyancy drives uplift
MICRO-NODE 03
Caldera Formation
- No mountain cone
- Chamber roof collapses inward
- Forms giant depression
- Often fills as lakes
MICRO-NODE 04
Hydrothermal Systems
- Heat near surface
- Geysers & hot springs
- Yellowstone's famous features
- Releases continuous pressure
MICRO-NODE 05
Continental Ash Fall
- Blankets entire continents
- Collapses infrastructure roofs
- Clogs water systems
- Destroys regional machinery
MICRO-NODE 06
Stratospheric Aerosols
- SO2 injection to stratosphere
- Forms sulfuric acid droplets
- Reflects incoming solar radiation
- Lasts for several years
MICRO-NODE 07
Volcanic Winter
❄️
- Severe global cooling
- Temperature drops by degrees
- Disrupted monsoon cycles
- Decadal climate shift
MICRO-NODE 08
Food System Collapse
- Shortened growing seasons
- Global multi-breadbasket failure
- Mass starvation risk
- No current resilience plan
MICRO-NODE 09
The Toba Bottleneck
- 74,000 years ago (Indonesia)
- Theoretical human population crash
- Genetic bottleneck evidence
- Near-extinction event
MICRO-NODE 10
Ground Deformation
- Magma pushes crust upward
- Measured by InSAR satellites
- Earthquake swarms increase
- Precursor to eruption
MICRO-NODE 11
Rhyolitic Magma
- Extremely high silica
- Thick, sticky, vicious
- Traps expanding gases
- Guarantees explosive force
MICRO-NODE 12

EVAC
PLAN
- Continuous GPS monitoring
- Strategic global food reserves
- Cannot be stopped
- Focus on surviving aftermath
