Types of eruptions at the Yellowstone Volcano

It is not common knowledge that Yellowstone actually has different types of eruptions. These eruption are mostly small compared to a supervolcano. According to the Yellowstone volcano observatory's website the last super eruption was 640,000 years ago. There has been approximately 80 smaller eruptions since then. Although these eruptions are significantly smaller they're still dangerous. The observatory reports that the last eruption was 70,000 years ago. Its also useful to read about the two different types of eruptions, rhyolitic and basaltic.These different magma types produce very different eruptions.

also interesting, this website reports that according to the history of the past eruptions, the next volcanic activity should be another one of these smaller eruptions and not a devastating super eruption.
