EMP vs Solar Storm: What’s the Difference?
Separate different mechanisms that are often blended together in preparedness marketing.
Practical, evidence-led approach: Ready Resolve distinguishes established emergency guidance from merchant claims and speculative scenarios.

Separate mechanisms
An electromagnetic pulse and a geomagnetic storm are not the same event. Avoid treating all grid-disruption scenarios as interchangeable.
Use primary sources
NOAA documents that geomagnetic storms can create geomagnetically induced currents that affect power systems, including historical outages.
Avoid absolute claims
Whether electronics or infrastructure are affected depends on event characteristics, exposure, coupling, design and protection. “Everything will fail” is not a responsible default conclusion.
What to do next
Turn this topic into one or two concrete household actions. Preparedness works better as a maintained system than as a one-time shopping list.
