Sudden Alarm

Suddenly a lot of sharp alarms rang all over the class.

It was about 17:00, when I was taking British Culture class.

Those noisy sounds were given from students' mobile phones.

One of my friends, whose phone had also been ringing loudly, told me that a big earthquake happened at Fukushima and we should be ready for protecting ourselves from shaking.

As you know, the shake was not strong here.

but...

I was so surprised that the recent mobile phones have a service of ringing emergency alarm automatically.

Convenience must save our lives. (´∀｀）
