The earthquake in Kyparissisikos bay “fouled” the rival Chelentis – Papadopoulos

O in the Cypriot Gulf on Friday morning (29.03. 24) became a reason to revive the conflict between the seismologists of Akis Tselentis and Gerasimos Papadopoulos. The earthquake occurred at 09:12 on Friday morning in the sea area near Strofades in the Kyparissisian Gulf open to Ilia. A minute earlier, attention 4.3 Richter had been noted, but the initial assessment by the Geodynamic Institute was referring to 5.6 Richter. The Geodynamic Institute issued a communication with clarifications. An announcement that caused the intense reaction of Gerasimos Papadopoulos. “The thriller with the supposedly double earthquake in the marine area of the Cypriot Gulf ended. Initially the National Observatory announced 2 magnitudes 5.6 and 5.7 earthquakes. Finally, after half an hour he announced 4.5 and 5.7. Such errors have occurred in the past. They must be eliminated. They create confusion and make the assessment difficult,” noted Gerasimos Papadopoulos to conclude: “As far as the substance is concerned, we are currently not sure if the 5.7 was the main earthquake. The area has made major earthquakes in the past,” wrote G. Papadopoulos. The Chelente reaction In the post of G. Papadopoulos the director of the Geodynamic Institute, Akis Celentis, rushed to respond. “Nishafi now with this retired physiologist former Geodynamics employee who did not respect the place where he ate bread and constantly comes out to the media and accuses us both of scientific failure and of empathy,” wrote A. Chelentis. “The man who has made predictions for all of Greece and if an event happens will come out and tell us he predicted it. A year ago it took me five months to calm down Thebes talking about 7 Richter. He does not even respect the tourist season by blowing tourism into the air,” he commented. The Communication of the Geodynamics on the approach and tsunami Detailed communication on the strong earthquake of 5.7 Richter east of the Stroads in the Kyparissisian Gulf published the Geodynamic Institute of the National Observatory of Athens. As he says about the earthquake: “On 29 March 2024 at 09:12:48. 74 we had east of the Sparrows very strong seismic vibration with a magnitude of 5.7 on the Richter scale. Before this earthquake at 09:11:54.78, i.e. 53.96 seconds ago, attention was made to the same area. The automatic system immediately and correctly identified the existence of two earthquakes and even calculated the epicenters in the right position. However, while the size of the second powerful earthquake was correctly calculated, the approach appeared with the wrong size in the automatic solution. The reason was that for all automatic systems, the magnitude calculation is typically based on a 120-second (window) recording interval for each earthquake. This is done so that the measurement includes a sufficient number of stations in the calculations, even for the area of the Greek arc and the border areas of Greece. In this case, the automatic system to calculate the size of the landing used a window in which the large earthquake had already entered and thus was affected. NCA’s Geodynamic Institute shift directly identified the existence of the error in size, however, it had to immediately send the urgent warning about a possible tsunami, since the magnitude of the earthquake was M 5.7 (over M 5.5). The tsunami warning was completed in a minimum time and specifically in just 6 minutes (9:18). Immediately afterwards, at 9:21:28 (3 minutes after) the detailed solution of the strong earthquake had been completed and at 09:23:17 (1 minute and 49 seconds after) the elements of the landing were also corrected.” In conclusion, he stressed: “NCA’s Geodynamic Institute reacted calmly and responsibly, even in this very difficult case of an earthquake (an earthquake with a difference of seconds and a need to warn tsunami) and announced the correct solutions at the very least possible time”.
