Warning! Pyroclastic Flows Inside (Volcanology) T Shirts
No need to have a temper to enjoy any of these wry scientific humor gifts featuring the saying "Warning! Pyroclastic Flows Inside". Includes a picture of pyroclastic flows sweeping down the flanks of Mayon Volcano, Philippines in 1984. Pyroclastic flows are fast-moving currents of hot gas and rock (collectively known as tephra), which travel away from the volcano after an explosive eruption at speeds generally as great as 700 km/h (450 mph. )Earth scientists, geologists, seismologist, volcanologists, and anyone who has a temper will enjoy any of these tongue-in-cheek geological humor gifts that will keep everyone guessing what exactly you are referring to!
