"A thicket of red tape and regulations have made it difficult for volcanologists to build monitoring stations along Mount Hood and other active volcanoes."
"Seth Moran is worried about Mount Hood.
In the 1780s, the volcano rumbled to life with such force that it sent high-speed avalanches of hot rock, gas and ash down its slopes. Those flows quickly melted the snow and ice and mixed with the meltwater to create violent slurries as thick as concrete that traveled huge distances. They destroyed everything in their path.
Today, the volcano, a prominent backdrop against Portland, Ore., is eerily silent. But it won’t stay that way.
Mount Hood remains an active volcano — meaning that it will erupt again. And when it does, it could unleash mudflows not unlike those from Colombia’s Nevado del Ruiz volcano in 1985. There, a mudflow entombed the town of Armero, killing roughly 21,000 people in the dead of night."
