Baluchistan provincial government spokesman Jan Mohammad Bulaidi said the death toll had climbed to 348 and another 552 people had been injured.
Doctors in the village treated some of the injured, but because of a scarcity of medicine and staff, they were mostly seen comforting residents.
The remoteness of the area and the lack of infrastructure hampered relief efforts. Awaran district is one of the poorest in the country's most impoverished province.
Just getting to victims was challenging in a region with almost no roads where many people use 4WD vehicles and camels to traverse the rough terrain.
"We need more tents, more medicine and more food," said Bulaidi.
Images from the village of Kaich showed the devastation. Houses made mostly of mud and handmade bricks had collapsed. Walls and roofs caved in, and people's possessions were scattered on the ground. A few goats roamed through the ruins.
The Pakistani military said it had rushed almost 1000 troops to the area overnight and was sending helicopters as well. A convoy of 60 Pakistani army trucks left Karachi early Wednesday with supplies.
Pakistani forces have evacuated more than 170 people from various villages around Awaran to the district hospital, the military said. Others were evacuated to Karachi.
Local officials said they were sending doctors, food and 1000 tents for people who had nowhere to sleep. The efforts were complicated by strong aftershocks.
Baluchistan is Pakistan's largest province but also the least populated. Medical facilities are few and often poorly stocked with supplies and qualified personnel. Awaran district has about 300,000 residents spread out over 29,000sq km.
The local economy consists mostly of smuggling fuel from Iran or harvesting dates.
It's also prone to earthquakes. A magnitude 7.8 quake centred just across the border in Iran killed at least 35 people in Pakistan last April.
Wednesday's shaking was so violent it drove up mud and earth from the seafloor to create an island off the Pakistani coast.
Pakistani Navy geologist Mohammed Danish told the country's Geo Television that the mass was a little wider than a tennis court and slightly shorter than a football field.
The director of the National Seismic Monitoring Centre confirmed that the mass was created by the quake and said scientists were trying to determine how it happened.
Zahid Rafi said such masses are sometimes created by the movement of gases locked in the earth that push mud to the surface.
"That big shock beneath the earth causes a lot of disturbance," he said.
He said these types of islands can remain for a long time or eventually subside back into the ocean, depending on their makeup.
