More than 1,000 people are killed, more than 2,300 have been injured and 30 are missing from the 7.7 Richter earthquake that shocked Myanmar, Friday (28.3.25) while fearing that the final number of dead would be five -digit.
According to seismologist Akis Zelentis, such an earthquake as in Myanmar can also affect Greece, under conditions.
As he explains, due to the very small focal depth of the earthquake in Myanmar, a special seismic wave category was created, the surface waves that have very long periods and spread on the surface of the soil at very long distances.
Thus, even distant earthquakes magnitude 7.5 to 8 on the Richter scale can affect the very tall buildings in Greece, large bridges, gas supply pipelines, wind turbines, and other large proprietary constructions.
Akis Zelentis’ post
“Is our country in danger of corresponding distant earthquakes that can happen in the Greek bow over time? (Where the Eurasian plate collides south of Crete with African) ??? Unfortunately yes! “
The reason that skyscrapers fell in Bakong at a distance of 1400 kilometers away from the focus was mainly because the seismic waves that arrived at Bakong due to their long journey through the earth’s cortex lost their high frequencies left with low (ie long periods).
In addition, due to the very small focal depth, a special seismic wave category was created, the surface waves that have very long periods and spread on the surface of the soil over very long distances.
This should concern us for Greece, because distant earthquakes 7.5-8.0R which is the potential of the Greek arc can affect the very tall buildings, large bridges, gas supply pipelines, wind turbines, and other large peculiarities.
This is how it is explained that the earthquake of ’81 mainly affected high -rise apartment buildings in Athens, and the last floor on it, as opposed to the ’99 earthquake that were striking mainly detached houses that were not so well built and some of the apartment buildings but the damage between the latter and the damage.
Also remember the 7th of Kythera in the Epiphany of 2006. Where all the country vibrated almost the same and even in Athens in tall buildings fell and various other small items from composite although it was over 200 km …
That is, the difference is that in such earthquakes we have a high low -grade soil oscillation but not with great acceleration, as opposed to local and superficial earthquakes that have high high soil movements and acceleration … “.
At the same time, the seismologist cites videos explaining what seismic waves are.
