The event was widely reported in the European press, albeit with some exaggeration and recorded by near-contemporary writers […] It was written of the town of Izmit that 'four-fifths was demolished and as many as 4 000 people, it was verified, were killed under the ruins. Six mosques collapsed, and 600 were killed inside. Aqueducts built by the infidels which bring water to the city collapsed, and a 25-metre long branch "migrated'' 10 paces, I heard fro1n someone who witnessed it' […] Sapanca town ‘was demolished, and most people killed’. […] Four or five villages in the region of Sevenit or Senentir (Sapanca?) were also destroyed, and 1000 people were killed or injured […] Dlizce town 'was demolished and most people were killed'. The town of Kazikli about 15 km east of Karamursel on the lzmit Gulf 'fell to the ground'. Karamursel was completely ruined, 'the courthouse was destroyed and the deputy judge died under the ruins', while prayers could not be conducted in the Karabali mosque owing to earthquake damage. Also half of the town of Yalova collapsed (reference 9116)
