AT 5.12AM ON the morning of 18 April 1906, an earthquake struck the northern Californian coast along the San Andreas fault, devastating the city of San Francisco.
According to the US Geological Survey, the powerful quake lasted about one minute with an epicentre near the city. It was felt as far as Oregon to the north and Los Angeles to the south.
Around 3,000 people are estimated to have died, the majority of whom perished in the city itself and thousands more were left homeless. San Francisco was engulfed in flames as a result of damage caused by the earthquake.
To mark the anniversary, TheJournal.ie has compiled a series of photographs taken in the immediate aftermath of the disaster as residents surveyed the damage to their homes and businesses:
