Some places in Japan have a comprehensive earthquake response system in place. After a quake, citizens each make their own way to a pre-arranged school, while teachers drilled in earthquake preparedness man cellular or satellite phones. People from other areas can then call in to check that friends and relatives living in the quake zone are okay.
在日本一些地區，本身擁有健全的社區防災體系，震災發生後，居民都會疏散到事先指定的學校，訓練有素的老師則立刻啟用無線電或衛星電話通信網，外地親友要找人就打電話到此詢問，只要知道親友在安置名單上即可。
