The lower Mekong River flooded from July to December in 2000. Especially, Cambodia and Vietnam were serious on inundation. The numbers of victims were 347 in Cambodia and 448 in Vietnam. The amounts of damage were 80 million and 350 million US dollars in Cambodia and in Vietnam, respectively. Water level reached to a record-breaking height at PhnonPenh. The main reasons of this flood were that heavy rainfall began earlier and two tropical cyclones approached to the catchment area. Other reasons were that some portions of dikes were changed to bridge to protect roads, Colmatage worked as intake from the main river and sedimentation deposited in channels and canals. Governments and international organizations are designing and planning some projects for flood control.

A major earthquake (M 6.8, 37.289 N, 138.870E, Depth 13km) occurred on October 23, 2004, at 5 : 56PM (local time) near Ojiya City, Niigata Prefecture, Japan. The JMA seismic intensity of 7 was recorded in Kawaguchi-machi for the first time after seismic intensity meters were installed. Aftershocks with the JMA seismic intensity scale of more than 5 minus had been measured for more than two weeks in the affected area. Forty people were killed, more than 4,500 were injured and more than 100,000 were evacuated for days. The number of totally collapsed houses exceeded 2,800. Strong shaking triggered more than 1,600 landslides, and some of them blocked up river channels in mountain area. The earthquake also caused major damage on civil structures. The Joetsu Shinkansen bullet train was derailed for the first time in its history of 40 years. The number of passengers was 151 and miraculously no one was injured.
