The Obelisk Gate (The Broken Earth, #2)

by N.K. Jemisin

Breathless Season: 1689–1798 Imperial. Proximate cause: mining accident. Location: Nomidlats, Sathd quartent. An entirely human-caused Season triggered when miners at the edge of the northeastern Nomidlats coalfields set off underground fires. A relatively mild Season featuring occasional sunlight and no ashfall or acidification except in the region; few comms declared Seasonal Law. Approximately fourteen million people in the city of Heldine died in the initial natural-gas eruption and rapidly spreading fire sinkhole before Imperial Orogenes successfully quelled and sealed the edges of the fires to prevent further spread. The remaining mass could only be isolated, where it continued to burn for one hundred and twenty years. The smoke of this, spread via prevailing winds, caused respiratory problems and occasional mass suffocations in the region for several decades. A secondary effect of the loss of the Nomidlats coalfields was a catastrophic rise in heating fuel costs and the wider adaption of geothermal and hydroelectric heating, leading to the establishment of the Geneer Licensure.
