Two bombs exploded in the crowded streets near the finish line of the 117th Boston Marathon on Monday, April 15, 2013.

At least three people were killed and more than 140 people were injured.

It is a tragedy and I am very sad and sorry for the victims, their families and friend.

Hungary Sludge Reservoir Could Collapse

I hope that this disaster will not happen again.

But the cracking wall of the alumina plant reservoir could collapse at any moment.

And the whole wall may collapse.

Hungarian Prime Minister Viktor Orban told reporters that a crack in the concrete wall widened by 2.76 inches (7 centimeters) overnight.

Officials have started to build dams to the north so that it won’t hit too many people.

Kolontar has been evacuated.

And they may evacuate the next town of Devecser.

Both were hit by the red toxic flood on Monday.

If the wall collapse, it will be a great tragedy for Hungary.

Rescuing Victims Of China’s Latests Disaster-Mudslides

Terrible mudslides, land slides and flash floods hit northwest China on Sunday.

In China’s Gansu province, entire villages were buried in water, mud, and rocks.

At least 127 people were killed and at least 1300 were missing.

About 45,000 people have been evacuated.

Reports said that 88 people were injured.

Rescuing victims in the hardest-hit Zhouqu county was really hard.

Streets were covered with mud as thick as two metres (yards) in some spots.

Cars and homes were buried in mud and debris while roads and bridges were destroyed.

The landslides swept mud, houses, cars and other debris into a river running through Zhouqu.

The Bailong River was blocked and the overflowed water flooded the valley.

The town was covered with mud and water.

Demolitions experts set off three sets of charges to clear debris that blocked the river.

Rescuers searched Monday for an estimated 1,300 people left missing after rubble-strewn floodwaters tore through a remote corner of northwestern China, just one of a series of flood disasters across Asia that have plunged millions into misery.

This is China’s latest disaster in 2010.

China was also hit by the worst flooding in a decade.

This tragedy happened just a few days after terrible flash floods and mudslides hit Kashmir.
