My notes on earthquakes from that doc:

Hydrogen is associated with Earthquakes and can maybe even predict them!

In areas with recent tectonic activity: “Higher hydrogen concentrations were observed,” and “hydrogen gas was observed in ground water.” [pg 20]

“[Correlated with earthquakes,] hydrogen concentrations measured at continuous monitoring sites show abrupt changes in concentration over several orders of magnitude, up to 10 times, in a short period of time.” [pg 40]

“Indeed, at epicenters of large earthquakes a reduction in the ozone layer above them has been observed.” [pg 40]

“A systematic study of hydrogen in aquifers shows that H2 concentrations are in- versely correlated with the age of the area's last tectonic activity.” [pg 41]

“Another study shows that hydrogen concentrations in earthquake-associated faults are usually much higher than concentrations in non-earthquake faults.” [pg 41]

‘During earthquakes hydrogen concentrations in fault zones have been shown to increase by several orders of magnitude.” [pg 41]

“Numerous articles discuss hydrogen as a good earthquake indicator and the possibility of monitoring hydrogen for the prediction of seismic events.” [pg 41] More detail below
