An unpublished internal FEMA report has finally been obtained via an FOIA (Freedom of Information Act) request, which highlights the extent of damage a major solar storm, what they call the “100 year geomagnetic storm,” would do to critical infrastructure in the U.S., including “Significant power grid collapses,” which “could require 4-10 years to fully restore.”
The internal “for official use only” document originated in 2010, and in February 2016, was requested by governmentattic.org and was released to the organization on May 24, 2017, according to the 70 page PDF they released on June 12, 2017, which includes the timeline of request to release, the FEMA final response communication with the requested data of any unpublished internal FEMA or unpublished contractor technical or management reports and studies concerning risks from geomagnetic storms, risks from solar flares, and risks from electromagnetic pulse.
The report covers a variety of scenarios, while detailing vulnerabilities and assessing risks, and while we encourage everyone to read the entire report (embedded below) for comprehensive understanding, we will highlight some of the most concerning below.
Under the category of “assessing the risk” on page 25, they highlight the 1859 Carrington-Hodgson, stating “Anecdotal observational records of low-latitude red aurora hint that the largest events may occur roughly every 500-600 years, before dropping the bombshell “However, events strong enough to severely impact modern systems may occur as frequently as once in 100 years .
Indeed two storms, 1859 and 1921, were of sufficient strength that their repeat today could cause large-scale power grid collapse.
The previously unpublished report also details how close we have already come to seeing the collapse of the Northeast and northern Midwest power grids back in 1989:
Further, the March 13, 1989 storm that collapsed the Hydro Quebec power grid in Canada came within seconds of collapsing the Northeast and northern Midwest U.S. power grid (Kappenman, 2005). Kappenman (2005) reports that “the size and intensity of this Westward Electrojet structure, had it developed 5- 7 h later, would have extended from east coast to west coast of the entire northern-latitude portions of the US power grid, and is likely to have produced much more significant consequential impacts … . ” It should be noted that the power grid, due to deregulation since 1989, is actually more vulnerable today (National Academy of Sciences, 2008).
Being an older report, the dates where certain events were projected have already passed, but since space weather never ends, their chilling warning when they state “The threat is real,” makes it very clear that the vulnerabilities of the infrastructure involved, has gotten worse, not better.
On page 13, shown in the chart below, they list the trigger/Scenario event as “CME arrives at Earth causing geomagnetic storm,” showing the warning times listed as “15 minutes for geoeffectivity (17 hours from flare sighting). Affects: GEO satellites on daylight side exposed to solar plasma ; Some satellite communications and GPS signals severely disrupted due to scintillation in ionosphere; HF systems may work due to increased ionization at ionosphere F Layer ; Significant power grid collapses may occur in North America and elsewhere; could require 4-1 0 years to fully restore; “Last mile” telecommunications lost where no backup power available (e.g. cable, VoIP, data networks, etc.)
