Turkish President Recep Tayyip Erdogan on Tuesday declared a disaster zone in the 10 southeastern provinces affected by the devastating earthquakes, imposing a state of emergency in the region for at least three months.

Erdogan said 70 countries have offered to help with the search and rescue operations in Turkey and that his government plans to open up hotels in the southwestern resort city of Antalya to temporarily house people impacted by the disaster.

More than 8,000 people have been rescued in southeastern Turkey since a powerful earthquake and aftershocks struck the region, Turkish Vice President Fuat Oktay said at a press conference on Tuesday.

Some 24,000 first responders are on the ground, including more than 3,200 first responders from 14 other countries who traveled to Turkey to assist with the massive search and rescue effort following Monday’s quake. They are carefully combing through the wreckage and looking for survivors amid the 6,000 buildings that have been either damaged or destroyed, according to Oktay.

Monday’s massive earthquake and powerful aftershocks have killed at least 3,419 people and injured another 20,534 in southeastern Turkey, Turkish Vice President Fuat Oktay announced during a press conference on Tuesday.

Meanwhile, at least 1,603 were killed and 3,649 injured in both government- and rebel-controlled areas of northwestern Syria, according to combined figures from the Syrian Ministry of Health and the Syrian civil defense and medical group that operates in opposition-held areas, known as the White Helmets.

More than 24 hours after devastating earthquakes, ABC News reporters on the ground are witnessing the fevered effort to rescue survivors at a collapsed apartment building in southeastern Turkish city of Diyarbakir.

ABC News learned that crews had recently rescued a woman from what used to be an eight-story apartment building, where the top half now rests on three flattened floors below. The front wall had fallen away, exposing what used to be homes with furniture, pillows and air conditioning units.

In and around the collapsed building, there was a flurry of activity -- but then a moment when it all came to a grinding halt. Generators were turned off, everyone stopped talking and the block went silent. Search and rescue teams thought they may have found another survivor. It was quiet for several minutes, but then the urgent effort returns.

Rescuers continued working in the cold, wet weather while also facing the threat of aftershocks. None of that has deterred them. They know this is a race against time.

Stephen Allen, USAID's Disaster Assistance Response Team leader for the agency’s earthquake response, said his top priority is getting two American urban search and rescue teams to the region.

"Every hour does count in the first few days,” he said.

The responders are en route to Turkey, where they are expected to land at Incirlik Air Base in Adana Wednesday morning local time, Allen said. They’ll immediately start the long journey to Adıyaman, a city in southeastern Turkey that’s been heavily impacted by the quake, but has not had access to many search and rescue teams, Allen said.

The Americans are bringing about 170,000 pounds of specialized tools and equipment, including hydraulic concrete breaking gear, saws, torches, drills and advanced medical supplies to treat and triage the wounded, he said. They will also have about a dozen dogs who Allen said will play a “very key” role in looking for survivors strapped in the rubble.

Sending search and rescue teams to a disaster site so far away is “not something that we would normally do, frankly,” he said, however Turkey officials asked for assistance because its own considerable national search and rescue capabilities are outmatched by the “size and scale” of the devastation.

“I do need to emphasize the level of devastation, the level of damage, and the expected result in loss of life is massive. It’s massive,” he said.
