The devastating 2023 earthquake sequence in southern and central Turkey near the Syrian border had a profound impact. The sequence consisted of two major earthquakes, resulting in widespread damage, tens of thousands of fatalities, and significant economic losses. The unexpectedly large size of the mainshock challenged existing understanding of fault systems, with findings suggesting unique rupture propagation mechanisms. The earthquakes also exhibited high ground acceleration values and exposed construction malpractice. The sequence's implications for seismic risk assessment in California are discussed, emphasizing the need for improved understanding, realistic simulations, and resilient infrastructure.
