What are the immediate impacts of the sustained seismic activity near Santorini, and what measures are in place to mitigate risks?

Following a marathon meeting of the Seismic Risk and Hellenic Volcanic Arc Monitoring Committees on Tuesday night, Professor Costas Papazachos reported that seismic activity remains unchanged, with measures staying the same. Since February 1st, over 1,100 earthquakes exceeding 3 on the Richter scale have been recorded, mainly along southwest-northeast faults near Anhydros, with recent activity shifting slightly towards Amorgos. This shift is considered normal.

How can Turkey's current approach to earthquake preparedness be improved to transition from a reactive to a proactive strategy?

Görür's concerns stem from the recent devastating earthquakes in February, where hundreds perished due to inadequate preparedness. He points to a reactive approach focused on damage control rather than proactive prevention. His proposed strategy involves detailed research on regional fault lines to assess vulnerability, and to create earthquake-resistant cities, requiring collaboration between government, local authorities, and citizens.

What are the key findings regarding the previously unknown characteristics and potential impacts of the recently discovered supercontinents within Earth's mantle?

Two massive, unmixed regions, or "supercontinents," have been discovered deep within Earth's mantle, one beneath Africa and the other under the Pacific Ocean. These structures, each hundreds of thousands of square miles, may act as anchors, influencing plate tectonics and potentially impacting surface phenomena like earthquakes and volcanism.

What is the immediate risk posed by the Yedisu Fault, and what specific actions should be taken based on Professor Görür's warnings?

Professor Naci Görür, a prominent seismologist, expressed serious concerns about the Yedisu Fault between Erzincan and Karlıova, Turkey, stating that its seismic recurrence period has passed and it is ripe for an earthquake. He highlighted that the February 6th earthquakes transferred energy to this area, increasing the likelihood of a significant event. His warnings were previously unheeded, despite prior alerts about Kahramanmaraş, Malatya, and Hatay.

What long-term economic and social impacts might result from this crisis, and what strategies could mitigate these consequences?

The situation underscores the vulnerability of volcanic areas to seismic activity. The economic impact on Santorini's tourism-dependent economy is expected to be significant, and ongoing seismic activity could trigger volcanic activity. The government's response and international aid may influence the recovery process.

How did the researchers use seismic wave data to gain new insights into the composition, age, and role of these deep mantle structures?

Analysis of seismic wave attenuation, alongside speed, provides new insights into the composition and age of these "supercontinents." The minimal energy loss suggests larger mineral grains, indicating an age of at least 500 million years, possibly much older, and a role as anchors in the mantle, contradicting the previously held belief of a well-mixed mantle.

What are the underlying geological factors contributing to the increased seismic activity in the Girit-Rodos arc region?

The northward movement of the African plate pushes against Anatolia, causing stress that is periodically released through smaller earthquakes. This tectonic pressure, ongoing for millions of years at a rate of 3-5 cm annually, has created a high-risk zone in the Girit-Rodos arc. The recent increase in seismic activity in Muğla, concentrated along the Gökova fault line, highlights this heightened risk.
