The last big one was the Toba eruption in Indonesia about 72,000 years ago. That one almost killed off the human race.&lt;p&gt;The Long Valley Caldera in California became more active in the 1970&amp;#x27;s. If this study&amp;#x27;s conclusions hold up under investigation and it only takes a few decades of activity before a &amp;quot;supervolcano&amp;quot; can erupt, we should monitor these caldera a bit more closely.</text><parent_chain></parent_chain></comment><story><title>A Surprise from the Supervolcano Under Yellowstone</title><url>https://nytimes.com/2017/10/10/science/yellowstone-volcano-eruption.html</url></story>
