The reason we care about the big eruptions [is] because they're also the ones that scale to the biggest hazards and biggest impacts, both locally and regionallysometimes globally.
Now scientists believe they've found a way to sleuth out the deep history of volcanoes such as Novarupta, and they're doing it with artificial intelligence.
When we applied our model to 800,000 years of ash layers in the Gulf of Alaska, we saw that Katmai was responsible for producing a lot of the eruption deposits in marine cores going back to 800,000 years, and they looked almost identical geochemically to the 1912 eruption.
