A 4.9 earthquake on the Richter scale struck near the island of Skiathos in the northwest Aegean Sea on Tuesday.

According to the revised solution of the Geodynamic Institute of Athens, the epicenter of the tremor, which was felt in some regions of Attica, was pinned 8 kilometers west of the island, with its depth estimated at 14.1 kilometers.

The latest quake was preceded by an earlier one measured at 4.7 on the Richter scale in the same location. Its depth was estimated at 13.1 kilometers.

Speaking to public broadcaster ERT, the president of the Earthquake Planning and Protection Organization (EPPO), Efthymios Lekkas, stressed there was no need for concern, adding the seismic activity in the region was a result of a small fault line already known to seismologists.

Greek authorities issued a set of precautionary guidelines for citizens to reduce risks in the event of an earthquake, focusing on securing household items and identifying safe areas in the home.

Residents are advised to firmly anchor shelves and bookcases to walls, and to move tall furniture away from doorways to prevent it from toppling and blocking exits. Water heaters, as well as fuel and water tanks, should be securely fastened.

Heavy objects should be placed on lower shelves, while items positioned above beds and sofas should be removed. Light fixtures and ceiling fans are also recommended to be properly secured.

Authorities further urge households to identify safe spots in each room — such as under sturdy desks or tables — and to avoid areas near glass surfaces, bookcases and exterior walls.

Finally, citizens are encouraged to regularly check that electricity and natural gas supply systems are functioning safely and properly.
