A strong M6.9 earthquake struck 58 kilometers away from the Toba supervolcano on August 15th. But do not worry, this earthquake was not volcanic in nature, although it could be argued that its occurrence might be related to why Toba exists in the first place. Today's video explains what I mean by this, discussing an August 15th 2026 earthquake that did not cause any reported damage. Note: Definition wise, all magnitude 6 range earthquakes are considered as "strong", so that is why I included that descriptive term in the video title.
