Was ist ein Vulkanausbruch einfach erklärt?
Eine Aschewolke steigt auf, Lava quillt aus dem Vulkan und fließt über die Erdoberfläche. Es dringt durch Kanäle und Spalten an die Oberfläche und tritt dort als glühend heiße Lava aus – der Vulkan bricht aus. Den Kanal, durch den das Magma nach oben quillt, nennt man Schlot, seinen Ausgang Krater.
What were the effects of the 1991 Mount Pinatubo eruption?
The second-largest volcanic eruption of the 20th century, and by far the largest eruption to affect a densely populated area, occurred at Mount Pinatubo in the Philippines on June 15, 1991. The eruption produced high-speed avalanches of hot ash and gas, giant mudflows, and a cloud of volcanic ash hundreds…
What type of volcano is Mount Pinatubo?
Mt. Pinatubo is a stratovolcano in the Philippines. June 12, 1991, it erupted, resulting in the second-largest eruption of the 20 th century.
What was the size of the ash cloud from Mount Pinatubo?
Ash Cloud. The eruption of Mt. Pinatubo in 1991 stands as the second largest eruption in the 20th Century (Mt. Novarupta, Alaska 1912 claims largest eruption fame). Ash deposits 5 cm (2 in) thick or more covered a land area of about 4,000 square kilometers (1,544 squares miles) burning crops and other plant life around Pinatubo.
Why does Pinatubo have a hole in its surface?
That „hole“ in the days immediately following the eruption of Pinatubo is due to interference by sulfur dioxide with the retrieval algorithm. There are high amounts of volcanic SO2 in the initial plume from the eruption.
