Italy earthquake leads to unpredictable change
Devastating earthquake, which hit Italy few weeks ago, has caused the Apennine Mountains to grow by up to 4cm in parts, research has found.
Current data from satellites and GPS stations show the range was permanently changed by the magnitude 6.2 quake because of movement along fault lines lying beneath, the National Institute of Geophysics and Volcanology (INGV) said.
Seismologists said it was the result of tectonic faulting beneath the mountains, where the Adriatic plate is being forced beneath the Eurasian Plate.“The earthquake caused a permanent deformation of the Earth’s crust,”
INGV researchers said.“It was generated by a fault line of over 18km, at an incline of around 50 degrees, which ran from north-northwest to south-southeast. The movement of this fault has caused an extension of the Apennine range of about 3-4 centimeters between the Tyrrhenian and Adriatic seas.”
The mountains stretch down the length of Italy, running into the Alps into the north and down to the coastal city of Reggio Calabria in the south.
