The 7.7 Magnitude Earthquake in Myanmar: A Warning for Los Angeles and Istanbul
The 7.7 magnitude earthquake that struck Myanmar on March 28, 2025, serves as a grim reminder of nature’s destructive power. The Sagaing Fault ruptured suddenly, releasing accumulated stress and shaking a vast area from Mandalay to Bangkok. Buildings crumbled, ancient pagodas turned to dust, and official reports confirm at least 1,600 fatalities, a number expected to rise. However, this disaster is not Myanmar’s alone. Seismologists warn that the event should serve as a wake-up call for cities like Los Angeles and Istanbul, both of which face significant seismic risks.
Sagaing Fault and San Andreas: Geological Twins
Myanmar’s Sagaing Fault bears striking similarities to California’s infamous San Andreas Fault. Both are strike-slip faults, where tectonic plates slide past each other horizontally. The recent Sagaing rupture extended 400 kilometers, whereas the San Andreas Fault stretches over 1,200 kilometers, capable of producing a similar disaster at any time (Wax, 2025). The shallow depth (10 km) and high energy release of the Myanmar earthquake strongly resemble the "Big One" scenario anticipated for Los Angeles (USGS, 2025a). A comparable event in California could collapse highways, rupture gas lines, and throw millions into chaos.

A Warning for Istanbul: The Silent Threat Under Marmara
The Sagaing Fault’s story resonates not only with the Pacific Rim but also with the seismic landscape of Turkey. Istanbul sits on the North Anatolian Fault Zone (NAFZ)—a tectonic sibling of San Andreas and Sagaing (Wikipedia, 2025). The 1999 M7.4 Gölcük Earthquake, which killed over 17,000 people, demonstrated NAFZ’s devastating potential.
Scientists now warn that Istanbul, with its 20 million residents, is due for another major event. If a shallow rupture like Myanmar’s occurs beneath the Marmara Sea, poorly constructed buildings and high population density could amplify destruction (USGS, 2025b).
Turkey’s Recent Tragedy: February 6, 2023
The Myanmar earthquake also brings to mind Turkey’s catastrophic February 6, 2023, earthquakes. Successive Mw 7.8 and 7.5 earthquakes along the East Anatolian Fault Zone claimed over 50,000 lives. Like Sagaing, the East Anatolian Fault is shallow and strike-slip in nature (IRIS, 2025). However, the destruction in Turkey far surpassed Myanmar’s due to higher population density and substandard building quality. Meanwhile, Myanmar’s civil unrest and political instability have hindered rescue efforts. These disasters force us to ask: How prepared are we?
Lessons for Los Angeles and Istanbul
The Myanmar earthquake serves as a mirror for Los Angeles and Istanbul. San Andreas Fault’s stress continues to build, keeping Californians on edge for the "Big One." Meanwhile, scientists estimate a 60% probability of a M7+ earthquake striking Istanbul within the next 30 years (EarthScope, 2025). Both cities face unique challenges: aging infrastructure, high population density, and the unpredictability of nature. Myanmar’s experience highlights a simple truth: faults do not warn—they just break.
Preparedness is Key
Science confirms that these earthquakes are inevitable, but the scale of destruction is in our hands. In Los Angeles, retrofitting structures and emergency response planning can mitigate disaster. In Istanbul, earthquake-resistant construction and public awareness campaigns can save lives. As Myanmar’s aftershocks continue, this catastrophe echoes as a global warning: Where will the next big earthquake strike, and how ready are we?

Myanmar'daki Büyük Deprem:
Los Angeles ve İstanbul İçin Bir Uyarı mı?
Sagaing Fayı ve San Andreas: Kardeş Faylar
Myanmar’daki Sagaing Fayı, Kaliforniya’nın meşhur San Andreas Fayı ile çarpıcı benzerlikler taşıyor. Her ikisi de doğrultu atımlı faylar – yani plakalar birbirine sürtünerek yatay bir kayma yaratıyor. Sagaing’deki bu son deprem, 400 kilometrelik bir kırılma hattı boyunca gerçekleşti; San Andreas ise 1.200 kilometrelik uzunluğuyla her an benzer bir felakete gebe (Wax, 2025). Bilim insanları, Myanmar’daki depremin sığ derinliği (10 kilometre) ve yüksek enerji salınımının, Los Angeles’ı vuran bir "Büyük Deprem" senaryosuna ne kadar benzediğini vurguluyor (USGS, 2025a). Kaliforniya’da böyle bir olay, otoyolları çökertebilir, gaz hatlarını patlatabilir ve milyonları kaosa sürükleyebilir.
İstanbul’un Gölgesindeki Tehlike
Türkiye’nin Yakın Hatırası: 6 Şubat 2023
Myanmar depremi, Türkiye’deki 6 Şubat 2023 felaketini de akıllara getiriyor. Doğu Anadolu Fay Zonu’nda art arda gelen 7.8 ve 7.5 büyüklüğündeki depremler, 50.000’den fazla can aldı. Sagaing ile Doğu Anadolu fayları, hareket mekanizmaları açısından benzer: ikisi de sığ, ikisi de doğrultu atımlı (IRIS, 2025). Ancak Türkiye’deki yıkım, Myanmar’dan çok daha büyüktü – yoğun nüfus ve zayıf yapı stoku bu farkı yarattı. Myanmar’da ise iç savaş ve siyasi kaos, kurtarma çabalarını baltalıyor. Her iki olay da bize şunu soruyor: Hazırlık ne kadar yeterli?
Los Angeles ve İstanbul’a Dersler
Myanmar’daki deprem, Los Angeles ve İstanbul için bir ayna gibi. San Andreas Fayı’nda biriken gerilim, her geçen gün "Büyük Olan"ı bekleyen Kaliforniyalılar için tanıdık bir tehdit. İstanbul’da ise Kuzey Anadolu Fayı’nın Marmara segmenti, sessizce saatini kuruyor – uzmanlar, 30 yıl içinde 7.0 üzeri bir deprem olasılığını %60’tan fazla görüyor (EarthScope, 2025). Her iki şehir de modern dünyanın kırılganlığını taşıyor: altyapı, nüfus yoğunluğu ve doğanın öngörülemezliği. Myanmar bize şunu öğretiyor: fay hatları uyarı vermez, sadece kırılır.
Hazırlık Zamanı
Bilim, bu depremlerin kaçınılmaz olduğunu söylüyor, ama yıkımın ölçeği bizim elimizde. Los Angeles’ta güçlendirilmiş binalar ve acil durum planları, İstanbul’da ise depreme dayanıklı yapılar ve bilinçlendirme kampanyaları hayat kurtarabilir. Myanmar’daki artçı sarsıntılar devam ederken, bu felaketin yankıları küresel bir uyarıya dönüşüyor: bir sonraki büyük deprem nerede olacak, ve biz buna ne kadar hazırız?
