As the seconds (secondary) ticked by while she stood on the beach after the earthquake, she thought she would be ok – but there was a large after-effect coming.
The main secondary effects of an earthquake are:
- Fires, often involving ruptured gas lines
- Tidal waves, which can cross entire oceans before engulfing land thousands of miles away.
- Landslides, which cause huge amounts of material to move very quickly
- Diseases, such as typhoid and cholera, which can spread in the unsanitary conditions often left behind by a major earthquake
