The Little Ice Age possibly released many shallow earthquakes in Korea and other places of the Earth. Decrease of temperature penetrates into hundreds meters deep into the Earth’s crust when its surface temperature is kept low for centuries. The resultant reduction of hydrostatic pressure in the crust can trigger earthquakes. According to historical records in Korea, comparatively much more earthquakes occurred in 1500s, 1600s, and 1700s. Near surface earthquakes among those could have been triggered by low temperature of the same periods.

Effective cooling can be regarded to have started around at the end of the Medieval Warm Period (A.D. 1200).
