A series of phreatic blasts occurred from the summit and escalated until a major explosive eruption took place on May 18, 1980, at 8:32 am. #geology #science #minerals #nature #crystals #geologyrocks #geologist #rocks #mineral #rockhound #crystal #earth #fossil #paleontology #mineralspecimen #mineralsforsale #landscape | Geology Science Official

Mount Unzen is perhaps most famous for its destructive and fatal eruption on June 3, 1991 at 4:08 pm.

Among these were French volcanologists Maurice and Katia Krafft, as well as American geologist Harry Glicken. The other forty fatalities consisted largely of those involved in the mass media, as well as firefighters, police officers, farmers and taxi drivers. | V

It’s a powerful reminder of why ventilation, sy

BoomBlastExplosion on Instagram: "This is the exact moment pyrotechnics stop being entertainment and start becoming a weapon. What you’re watching sits on the razor’s edge between controlled burn and uncontrolled detonation. The difference isn’t the flash — it’s the pressure. The casing. The confinement. The instability.
