Major Earthquakes In 2023: The year 2023 has seen its share of significant earthquakes, causing widespread damage and loss of life. Here’s a look at some of the major earthquakes that struck the world this year.
February 6: Turkey-Syria Earthquakes
An earthquake of moment magnitude (Mw) 7.8 struck southern and central Turkey and northern and western Syria on 6 February 2023. It was followed by an Mw 7.7 earthquake that was centered 95 km (59 mi) north-northeast from the first. There was widespread damage and tens of thousands of fatalities.
The Mw 7.8 earthquake is the largest in Turkey since the 1939 Erzincan earthquake of the same magnitude and also one of the strongest earthquakes ever recorded in the Levant. It was felt as far as Egypt and the Black Sea coast of Turkey. There were more than 30,000 aftershocks in the three months that followed.
An estimated 14 million people, or 16 percent of Turkey’s population, were affected. Development experts from the United Nations estimated that about 1.5 million people were left homeless.
The confirmed death toll stood at 59,259: 50,783 in Turkey and 8,476 in Syria. It is the deadliest earthquake in what is now present-day Turkey since the 526 Antioch earthquake and the deadliest natural disaster in its modern history.
Damages were estimated at US$148.8 billion in Turkey, or nine per cent of the country’s GDP, and US$14.8 billion in Syria.
