Iran's seismological centre in Bushehr province, linked to Tehran University, registered the quake at a magnitude of 6.1.
The Sun, another Hong Kong newspaper, accuses the State Seismological Bureau of failing to give advance warning of the earthquake.
The Iranian Seismological Center said the earthquake, which it put at magnitude 7.5, had struck Iran's Sistan and Baluchestan province.
Early reports from international seismological organisations calculated a magnitude of 7.8 for the event and timed its occurrence at 10:44 GMT.
Only 58 people have been rescued from demolished buildings across the quake area, China Seismological Bureau spokesman Zhang Hongwei told Xinhua.
China, a country with over 4500 years of recorded history, gave the world, gunpowder, paper, compasses, movable type, and even the seismological detector.

It is interesting to talk to Californians about their attitudes to this, because they live here in the clear knowledge that they are sitting on a seismological time bomb.
The quake measured by China's seismological bureau at magnitude-7 and the U.S. Geological Survey at 6.6 struck the steep hills of Lushan county shortly after 8 a.m. toppling buildings, many of them older brick structures.
He concluded that New York can expect a magnitude 5 quake once every century, a magnitude 6 quake every 670 years and a magnitude 7 quake every 3400 years ( Bulletin of the Seismological Society of America, vol 98, p 1696).
The technology processes remote-sensing data, including data from the LANDSAT and RADAR satellites, in combination with ground truth data provided by a ground penetrating radar and other information drawn from geological, hydrogeological, geographical, hydrological and climate data and, when dealing with deep aquifers, seismological data.
Dr Bilham and Vinod Gaur, from the Centre for Mathematical Modelling and Computer Simulation in Bangalore, writing late last year in Current Science, said that until recently Indian seismological research has neglected a technique known as geodesy, which measures the strains accumulating in, and distorting the surfaces of, plates.
