#Hydrothermal eruption sends tourists running in #Yellowstone
Part of #BiscuitBasin, just north of #OldFaithful, is closed after a hydrothermal explosion Tues morning.
Hydrothermal explosions occur when hot water creates bubbles of steam, leading to underground pressure that eventually bursts through the surface. …It’s not unlike the steam that builds up inside a sealed pressure cooker.

@Nonilex Just a supervolcano showing signs of possibly erupting. 
@lawyerjsd @Nonilex Vulcanologists say there’s no danger of that.
Active areas blowing off steam is good, as long as you’re not standing next to them.
@lawyerjsd @Nonilex “The explosion does not reflect any change in the volcanic system and “no other monitoring data show changes in the Yellowstone region,” the park’s statement said. Sims said the volcanic and hydrothermal systems are separate.
“These explosions are common [in Yellowstone],” Sims said. “If magma were involved there’d be far more ground deformation, gas emissions and all around changes, whereas this is an isolated pocket of steam that caused the ground to explode.”
