A strong earthquake has hit the town of Galta 200 kilometres north of Madras. The earthquake hit the town at 7:15 yesterday evening. The earthquake measured(量出) 7.2 on the Richter scale(里克特震级), the strongest for five years.

The earthquake happened as most people were having their evening meal at home. There were very few people outside in the streets. Buildings fell down and many fires started. The electricity and water were cut off.

As it was dark, the emergency services had a lot of problems. There was no electricity for lights, and there was no water to put out the fires. Early this morning, planes flew over the town to see the damage.

The emergency services are now trying to reach the town. The nearest airport is at Bandel, about 100 kilometers away. The railway station at Galta is closed, because four bridges fell down in the earth. The nearest train station is 32 kilometres away at Solan. We shall have more reports for you during the day.
