On April 23, 2025, at 12:49 p.m., a 6.2-magnitude earthquake struck off the coast of Silivri in the Sea of Marmara. The Disaster and Emergency Management Authority (AFAD) identified the epicenter approximately 23 kilometers off the coast of Istanbul’s Silivri district, with the quake occurring at a depth of 6.92 kilometers beneath the seabed. Boğaziçi University’s Kandilli Observatory and Earthquake Research Institute recorded the magnitude at 6.1. The tremor was felt across Istanbul and in neig

Richter Scale is a logarithmic scale used to determine the magnitude of an earthquake, that is, the quantitative measure of seismic energy released at the Earth’s surface. This scale was developed in 1935 by American seismologist Charles Francis Richter. Richter’s goal was to create an objective and comparable system for classifying earthquakes occurring in Southern California. In this context, the scale was based on measurements taken with a Wood-Anderson type short-period seismograph, using th

The Sixth February Earthquake Commemoration Ceremonies are memorial programs held across various provinces of Türkiye to honor those who lost their lives in the earthquakes centered on Kahramanmaraş on 6 February 2023, described as “the disaster of the century.” The ceremonies held on the second anniversary of the earthquake included recitations of the Establish’one-ı Kerim, moments of silence, marches, and other memorial events. On 6 February 2023, Earthquakes with magnitudes of 7.7 and 7.6 cen

On 22 May 2025, a magnitude 6.1 earthquake occurred off the coast of the Greek island of Crete. The earthquake was felt in some regions of Greece and Türkiye but did not result in any loss of life or major structural damage. Key Characteristics of the Earthquake The earthquake occurred on Thursday, 22 May 2025, at 06:19 local time. The epicenter was determined to be near the eastern coast of Crete, approximately 56 to 81 kilometers northeast of the town of Neapolis, in the Aegean Sea. The focal

Earthquakes are natural disasters characterized by sudden and destructive effects that cannot be precisely predicted in advance. Therefore, individual preparedness measures taken before such an event are of vital importance. An earthquake kit is a readily accessible and functional preparedness tool that enables individuals to meet their basic needs during and after a disaster. The preparation of an earthquake kit aims to ensure that individuals can sustain themselves independently, considering t

Seismic isolation (earthquake isolation) is an engineering solution that aims to reduce the seismic energy transferred to a structure by placing specialized systems between the foundation and the superstructure, thereby protecting buildings from the destructive effects of earthquakes. The primary objective of this system is to increase the natural vibration period of the structure, preventing it from entering resonance with the dominant period of the ground. As a result, the structure experience

On 30 July 2025 at 11:24 local time, an earthquake of magnitude 8.8 occurred off the coast of the Kamchatka Peninsula in the far east of Russia. The US Geological Survey (USGS) determined the epicenter to be approximately 119 kilometers east-southeast of the city of Petropavlovsk-Kamchatsky and recorded the focal depth at 19.3 kilometers. The German Research Centre for Geosciences reported the magnitude as 8.7. The Geophysical Service of the Russian Academy of Sciences, Kamchatka Branch, stated

On 20 July 2025, a series of earthquakes occurred off the coast of the Kamchatka Peninsula, part of the Russian Federation, and were felt across the region. The largest of these shocks measured 7.6 in magnitude and originated on the ocean floor of the Pacific Ocean, affecting several settlements including Petropavlovsk-Kamchatsky. Following the earthquakes, temporary tsunami warnings were issued by national and international agencies, but no significant damage or loss of life was reported. Chara

An earthquake is a natural disaster whose timing cannot be precisely predicted in advance and can cause significant loss of life and property. Measures taken before, during, and after an earthquake are vital to mitigate its effects. In this context, conscious action at both individual and societal levels is necessary. Measures That Can Be Taken Before an Earthquake 1. Ensuring Structural Safety The compliance of buildings with seismic regulations must be verified by qualified professionals. Stre

Tokat Earthquake is a 5.5 magnitude earthquake that occurred on 13 March 2026 in the Niksar district of Türkiye’s Tokat province. The tremor struck at 03:35 and was felt in surrounding provinces. Characteristics of the Earthquake The epicenter of the earthquake is located in Niksar district of Tokat. The magnitude was measured at 5.5 and the tremor was determined to have originated at a depth of approximately 6.37 kilometers below the surface. The earthquake was not only felt in Tokat but also i
