Deprem Oldu is a Türkiye-focused earthquake monitoring website that brings together recent seismic information from multiple national and international sources. It reports data attributed to AFAD, Kandilli Observatory, USGS, EMSC, GFZ and IRIS, helping visitors follow earthquakes across Türkiye and nearby regions in near real time. The site offers a feed of recent events with details such as magnitude, location, reported time, depth and data provider.

Visitors can explore earthquake information through dedicated sections for city-based listings, an interactive map, statistics and a blog. A separate view highlights earthquakes of magnitude 3 and above, making larger events easier to review alongside the broader activity feed. Listings include events in Turkish provinces as well as surrounding areas, with entries linked to further details.

By organizing information from several monitoring agencies in one place, Deprem Oldu provides a convenient reference for people seeking current earthquake reports, geographic context and updated summaries of seismic activity. Its service is informational, centered on accessing and browsing earthquake data rather than forecasting or issuing official alerts
