Alaska had only 2 seismograph stations at the time of the 1964 earthquake; by the mid-2000s, 197 seismic monitoring sites had been deployed across Alaska and Western Canada.

The 1964 earthquake didn't just advance theoretical science — it drove sweeping practical changes. Alaska adopted strict new building codes, particularly for large structures, placing it alongside California as having the most rigorous earthquake construction standards in the US. The payoff came in 2018, when a 7.0 quake struck Anchorage [1] — Chuck "A 7.0 earthquake struck Anchorage in 2018 — powerful enough to cause $76 million in damage and injure 117 people — but killed no one. That'…" 29:05 . Buildings held. Roads crumbled, 117 people were injured, and $76 million in damages accrued — but nobody died. That outcome would have been unthinkable in 1964. The monitoring infrastructure underwent an equally dramatic transformation [2] — Josh "The proliferation of seismographs across Alaska and the American West wasn't driven by earthquake science — it was driven by the Cold War n…" 30:32 . At the time of the earthquake, Alaska had just 2 seismograph stations, the oldest installed 60 years prior. Within a decade there were 90; by the mid-2000s, 197 stations covered Alaska and Western Canada. Josh reveals an unexpected source of this infrastructure boom: the Cold War nuclear arms race. Governments had deployed seismographs to detect secret foreign nuclear tests, and only later repurposed the networks for earthquake monitoring. The combination of better buildings and better monitoring produced the National Seismic Hazard Map — a comprehensive tool that tells planners exactly where to build and where not to, born directly from the science the 1964 earthquake ignited.
A 7.0 earthquake struck Anchorage in 2018 — powerful enough to cause $76 million in damage and injure 117 people — but killed no one. That's the direct result of Alaska adopting some of the strictest building codes in the US following the 1964 disaster.
A 7.0 magnitude earthquake struck Anchorage in 2018, injuring 117 people and causing $76 million in damage, but killing no one — a testament to post-1964 building code improvements.
The proliferation of seismographs across Alaska and the American West wasn't driven by earthquake science — it was driven by the Cold War nuclear arms race. Governments deployed seismographs to detect secret nuclear tests abroad, and only later redirected that monitoring infrastructure toward earthquakes.
The widely cited ego-depletion model — the idea that willpower is a finite resource that gets depleted — failed to replicate in follow-up studies.
Humans are estimated to have 5,000–7,000 thoughts per day, yet can recall essentially none of them afterward, highlighting why in-the-moment emotional tracking matters.
A large Harvard study found that a wandering mind is an unhappy mind — people report greater happiness when their attention is tethered to the present, even if the task is unpleasant.
A key study finding that we have a 'credit card's worth of plastic' in our bodies was likely skewed because researchers used nitrile gloves that shed plastic particles onto the microplastic detector.
Emotionally sensitive people have a hyperactive amygdala, an underactive prefrontal cortex, and a frayed connection between the two — making emotional regulation structurally harder.
Rejection sensitivity can be observed as early as age 2 or 3, suggesting it has strong developmental and likely genetic roots.
A Yale study found that non-judgmental observation of emotions — without rushing to resolve them — reduces activation in the brain, making it a powerful regulation tool.
Dan Gilbert's research found that the psychological immune system — the brain's ability to justify and find satisfaction in choices — activates most powerfully when a decision is perceived as irreversible.
Barry Schwartz's research found that maximizers — people who try to optimize every decision — tend to achieve objectively better outcomes but report lower happiness than satisficers who choose 'good enough.'
