2. – Fires can be caused when earthquakes damage electrical power stations or gas lines. These fires can be impossible to stop sometimes. In 1906 in San Francisco, fire caused by an earthquake killed more people than the earthquake itself.

Natural disasters
The definition of natural disasters is any catastrophic event that is caused by nature or the natural processes of the earth. The severity of a disaster is measured in lives lost, economic loss, and the ability of the population to rebuild. Events that occur in unpopulated areas are not considered disasters. So a flood on an uninhabited island would not count as a disaster, but a flood in a populated area is called a natural disaster.
All natural disasters cause loss in some way. Depending on the severity, lives can be lost in any number of disasters. Falling buildings or trees, freezing to death, being washed away, or heat stroke are just some of the deadly effects. Some disasters cause more loss of life than others, and population density affects the death count as well.
Scientists, geologists, and storm watchers work hard to predict major disasters and avert as much damage as possible. With all the technology available, it's become easier to predict major storms, blizzards, cyclones, and other weather related natural disasters. But there are still natural disasters that come up rather unexpectedly, such as earthquakes, wildfires, landslides, or even volcanic eruptions. Sometimes, a time of warning is there, but it's often very short with catastrophic results. Areas that are not used to disasters affected by flash floods or sudden hail storms can be affected in an extreme way.
Read the text and decide if each statement is true (T) or false (F).
