On Wednesday morning at a quarter past five came the earthquake. A moment later, the disaster was a fact. South of Market Street, in the working-class neighbourhoods and in the factories, fires started. Within an hour of the first quake, the smoke could be seen 100 miles away. The sun was red in the dark sky. There was no stopping the fires. The firefighters to whom the task was given did their best but there was no way to organise or communicate. The railway tracks were now useless and there was no water in water pipes. All of the ways man had made to keep the city safe were gone in the 30 seconds the earth moved.
Main idea:
The earthquake happened on Wednesday morning and within an hour fires statrted. Firfighters did their best, but in vain.
