Up to 30 buildings collapsed in Ercis, including a dormitory, and 10 buildings collapsed in Van, Deputy Prime Minister Besir Atalay said.
Rescuers in Ercis scrambled to find survivors in a flattened eight-story building that had shops on the ground floor, television footage showed. Residents sobbed outside the ruins, hoping that missing relatives would be rescued.
"My wife and child are inside! My 4-month-old baby is inside!" CNN-Turk television showed one young man crying.
Witnesses said eight people were rescued from the rubble, but frequent aftershocks were hampering search efforts, CNN-Turk reported.
"There are so many dead. Several buildings have collapsed. There is too much destruction," Zulfikar Arapoglu, the mayor of Ercis, told NTV television. "We need urgent aid. We need medics."
The quake's epicenter was in the village of Tabanli, 10 miles from Van.
Between the aftershocks and the number of people feared trapped in some of the collapsed buildings, the death toll is expected to rise. Authorities had no word on damages or casualties from the remote villages in the region, but local officials beginning to assess damage via helicopter.
Knee-high floods began to appear in some outer districts of the city, a day after authorities said they would take the risky move of releasing some waters that had been building up in recent days behind barricades fashioned along the city's northern outskirts. The idea is to let some waters run through the canals that crisscross Bangkok to escape to the sea, but it was unknown whether the operation could be executed without inundating large parts of the capital.
In Thailand, more than 200 major highways and roads are now impassable, while several key industrial estates have been inundated. Damages are expected to tally at least $6 billion and shave up to two percentage points off gross domestic product, according to economists' estimates. Humanitarian groups said parts of the affected provinces-- covering about a third of Thailand -- are inaccessible, with some towns under water more than six feet high.
There are several industrial parks around Bangkok that provide components for products from companies such as Toyota [NYSE: TM], Apple Computers [NASDAQ: AAPL] , Honda Motors [NYSE: HMC] and Sony [NYSE: SNE] that have halted production at their Thai facilities due to the ongoing flooding, further disrupting supply chains already in disarray from the March 2011 quake and tsunami that struck Japan.

Some of the expressways in and out of the capital had literally become parking lots as the high overpasses were the only high ground that the motorists were able to find. Thai Prime Minister Yingluck Shinawatra and over government officials have warned that the floodwaters could take as long as 6 weeks to fully receede. Earlier this month, the Kingdom's State Railway of Thailand shut down freight and passenger service to two northern cities while more recently it offered tourists refunds on tickets rendered unusable due to suspension of service because of the floods.
