CNN News:菲律宾火山喷发 学校停课航班取消

Which of these nations is located on the eastern side of the South China Sea? Vietnam, Indonesia, Philippines, or Malaysia.
Tough question but it's the Philippines who's capital is Manila that's located east of the South China Sea.

A state of emergency's been declared near that capital because of a recent eruption at the Taal Volcano. It's not the most active one in the Philippines, but volcanologists say Taal is very dangerous because it's erupted in the past and because it's located near populated areas. The United Nations estimates that more than 450,000 people live in the volcano's danger zone. The state of emergency means schools are closed, so they along with local convents can be used as shelters. Government offices are also closed and flights have been cancelled because volcanic ash can melt inside jet engines and badly damage them.
