The scenario for which equally strong shocks can occur compared to that which took place yesterday in Myanmar And “quite improbable»Even if possible. “We will surely have some some Establishment shocks also of magnitude around 6».
To explain it to the ANSA is Lucia margheriti, Director of the Earthquake Observatory ofNational Institute of Geophysics and Volcanology (Ingv).
Others important earthquakes on this fault they date back to just under a century ago: «Between the 1929 and 1931 there have been Four shocks of magnitude greater than seven»Remember Margheriti. «This makes us think that the so -called can be verified in this region phenomenon of cascade earthquakes».
The 7.7 magnitude earthquake in Myanmar It happened “along a passed faulttherefore with prevailing horizontal movementwhich is located just along the margin between the Indian plaque and that Euroasian», The seismologist points out. “A Segment of about 200 kilometers And this explains the magnitude of the earthquake ».
After 12 minutes from first shock “A important replyre -evaluated now as magnitude 6.7. There were then in the following hours Other earthquakesespecially in the southern part of the fault that moved yesterday, but all of maximum magnitude around 5 And a little more ».
There passed fault accommodate it continuous movement between the Indian and the Eurasian plaque. «These two busty plaques they move each other to one speed of about 40 millimeters a year», And the fault affected by the earthquake” accommodates at least half of this shift “.
