Progress volcanic eruption in Iceland: The worst fear to last a year, the European agricultural crops
The Wall Street Journal
The original question: What Next From Iceland’s Volcano?
Cheer in the wind and ice, under the very common volcanic eruption in Iceland actually turned into a crisis. European Aeronautic paralyzed, millions of people trapped in the airport. With the continuing volcanic eruption in Iceland, what will happen next crisis? U.S. “The Wall Street Journal” on April 20 forecast of future volcanic eruption in Iceland three scenarios, the worst case is that this eruption could last several months, a large number of people killed.
Suppose a: better within a few days
The best assumption is that in the next few days, the volcano eruption will gradually decline until the disappearance of, or all of the ice are melting. Scientists are trying to send aircraft to the volcanic region, analysis of how much ice left. However, these aircraft may be surrounded by volcanic ash cloud, blocking line of sight.
Hypothesis two: continue for many months
The most likely scenario is to repeat the 1821 volcanic eruption scenario, intermittent eruptions that lasted 13 months. If this situation occurs again, the European aviation may have to prepare to play “cat and mouse” game, that the aircraft can only be a brief quiet or volcanic ash cloud spread to one direction when a short flight. In this case, the pilot may always be in constant fear of encounter volcanic ash, because ash will stifle their engines, the aircraft broke the glass. Since 1980, about 90 aircraft have encountered volcanic ash, one quarter of the aircraft engine is off, the last almost caused a fatal disaster.
Assumption 3: the eruption caused a greater
The worst assumption is that this will trigger another volcanic eruption a larger eruption. There are currently 35 active volcanoes in Iceland, a volcanic eruption could trigger a chain reaction of other volcanoes. Worst case occurred in 1783, when the volcanic eruption lasted for 8 months, almost all of Iceland killed livestock, agricultural crops, resulting in a quarter of the population of Iceland and the European continent tens of thousands of deaths. That year was known as the terror of the “year without a summer” unusually cold weather in Europe, which led to continued poverty for many years. Many people even believe that it may encourage the outbreak of the 1789 French Revolution indirect factors.
