Earth crust becomes visible as Iceland melts!


It would not be wrong to say that Iceland’s ice is melting real fast. So fast, that earth crust has started to reveal up to 1.4 inches a year. All this has happened after a swift glacier meltdown.

According to a team of University of Arizona, the Iceland’s ice area is reducing rapidly and earth crust is popping up out of the glaciers which had been under snow for a long time. Scientists also believe that if the ice melt will continue at this rate, there will be chances of numerous volcanic eruptions.

The logic that makes sense here is that glaciers are really heave, and most of the time they are pulling earth down that exists under them. Few years back, geologists found out that these huge blocks of ice are getting thin, and the earth crust beneath them is popping up and revealing itself.

However, scientists are still trying to find out if the earth’s popping up is due to a glaciers melt down since long or its due to climate change overall. According to Richard Bennett, a geosciences professor, the earth is under observation for most of its climate changes. If the melting keeps going on at such rate, some areas of Iceland will be popping up at the rate of 1.6 inches per year by 2025.

According to Kathleen Compton, a geosciences doctoral candidate, the problem for Iceland is that high heat at lower pressure creates a scenario in which rocks are melted, which creates more magma. The shocking news in only a matter of concern for people of Iceland, but also for everyone else. In 2010, the volcanic eruption around Iceland cost billion of dollars to global economy. Some GPS receivers in Iceland were placed in 1995. Bennett and his colleagues installed around 20 GPS devices in Iceland in year 2006 and 2009. This installation provided a better coverage of Iceland area. The five biggest Icebergs are located in central and southern part of Iceland, and the GPS receivers are at least 20 miles apart from each other. These GPS devices were initially used for environmental activity including earthquakes and volcanic activities.

In addition, other researchers had also been working on ice melting rate since 1995. Some scientists believe that there has been significant change in temperatures since 1980, which could be another cause of ice melting in Iceland.

The team’s additional next step is to analyze the earth crust visibility data during different times of year, as ice blocks grow during winter and melts during summers.
