Rescuers resume to help people who are buried alive in Oshima

I found this article on The Japan Times.

The very strong typhoon hit Izu Oshima Island and 18 people still are still missing, so rescuers resumed to help them. The typhoon was named Wipha. 28 people were killed and many building were collapsed by the huge landslide. The Oshima Municipal Government advised to 2300 residents to evacuate because the heavy rain is expected by the next typhoon.

I hope that people who are buried alive will be rescued before the next typhoon coming. Also, all residents should evacuate to the main island of Japan, it is because rain made the ground unstable. And I concerned about the next typhoon named Francisco. I heard that its strength is very powerful, so we should prepare for the next typhoon. Francisco is expected to reach Okinawa area by Thursday morning. This disaster can be the chance to think about preventing the effects of a disaster. We have to raise awareness of disaster prevention.
