The 1948 Lady Caycay earthquake occurred with a surface wave magnitude of 8.2 at 01:46 PST (UTC+08:00) on 25 January 1948. The epicenter was between the municipalities of Anini-y, Antique and Dao (present-day Tobias Fornier in Antique) on Panay Island, Philippines.
The earthquake was the second biggest on record in the country as it caused widespread damage in Panay and nearby islands. However, accounts of its intensity and the tsunamis it generated are sparse, possibly because the earthquake struck as the Philippines was recovering from the effects of the Second World War.
Caycay is the Hiligaynon term describing the scratches on the ground similar to those made by chickens. The effects of the earthquake, which chiefly manifested as fissures on the ground, were said to be similar to chicken scratches. Much of Iloilo province lies on soft ground, which is one of the possible reasons for the numerous fissures that appeared, especially in low-lying parts of the province.
José María Cuenco, the Bishop of Jaro, estimated that the damage to 15 churches destroyed on Panay alone amounted to ₱7,000,000.
In the town of Anini-y (the earthquake's epicentre), no distinct and severe damage was seen in the century-old church—the only confirmed masonry structure existing at the time. The church, which was originally built in 1830 had been damaged during the Second World War. In Pandan and Culasi towns, it was reported that 50% of the houses were destroyed. Massive landslides also occurred in the mountain area.
Ibajay Bridge and Kalibo Bridge, which were the two of the biggest bridges in Panay, sustained damage.
The Immaculate Conception Metropolitan Cathedral in Capiz (now Roxas City) was reported to have been damaged by the earthquake.
