supervolcanic

And I think the setting in The Road is post-volcanic or post-supervolcanic, because some of the stories I'm working on are in a similar setting and The Road featured the unmistakable hardened slag on things like highways, and burned away trees, and smoking hot springs, etc.

One possible cause for this was a catastrophic supervolcanic event some 75,000 years ago, which may have reduced our own species to as few as a thousand breeding pairs and helped to wipe out all human branches except for h. sapiens and h. neandertalis.

This webpage by Ken Wohlenz of Las Alamos National Laboratory hypothesizes that there was a supervolcanic caldera of which Krakatoa was a part, which erupted around 535 CE.

The alternative is a supervolcanic eruption also called a superplinian or hyperplinian eruption.

Some of the volcanoes are notable for their eruptions, for instance, Krakatau for its global effects in 1883, Lake Toba for its supervolcanic eruption estimated to have occurred 74,000 Before Present which was responsible for six years of volcanic winter, and Mount Tambora for the most violent eruption in recorded history in 1815.

The risks associated with catastrophes such as asteroidal/cometary impacts, supervolcanic episodes, and explosions of supernovae/gamma-ray bursts are based on their observed frequencies.

"Previous supervolcanic eruptions have been linked to mass extinction events, such as the Permian extinction 250 million years ago - which wiped out more than 90 per cent of marine species and roughly coincided with the Siberian Traps eruption, the largest in history."

The theory - first proposed by Stanley H. Ambrose of the University of Illinois at Urbana-Champaign in 1998 - holds that the supervolcanic event at Lake Toba intensified Earth's last ice age by releasing so much ash into the atmosphere that sunlight was blocked out for six years.

Although humans survived the event, researchers have detected increasing activity underneath a caldera at Yellowstone National Park, where some suspect another supervolcanic eruption will eventually take place.
