Many survivors of Morocco's most powerful earthquake in more than a century are struggling in makeshift shelters after a fourth night outside, with rescuers yet to reach remote mountain villages that suffered some of the worst devastation.
The death toll from the 6.8 magnitude quake that struck in the High Atlas Mountains late on Friday stands at 2862, with 2562 people injured, but those figures look likely to rise.
Rescuers from Spain, Britain and Qatar are helping Morocco's search teams, while Italy, Belgium, France and Germany have all offered to send in specialists.
Hopes of finding survivors under the rubble are fading, not least because many of the traditional mud brick houses common in the mountain villages crumbled to earthen rubble without leaving air pockets.
Along the Tizi n’Test road that passes through some of the most remote areas, survivors were critical of the rescue efforts by the government, which they accused of failing the most devastated hamlets.
"The problem is that the authorities are focusing on the bigger communities and not the remote villages that are worst affected," said Hamid Ait Bouyali, 40, who had spent the night along the road on the outskirts of Rakte.
Some villages had yet to receive any help because roads were blocked by landfalls.
In Amizmiz, a large village at the foot of the mountains that has turned into an aid hub, some people made homeless by the quake had been provided with yellow tents by the authorities, but others were still sheltering under blankets.
"I am so scared. What will we do if it rains?" said Noureddine Bo Ikerouane, a carpenter, who was camping with his wife, mother-in-law and two sons, one of whom is autistic, in an improvised tent fashioned from blankets.
Omar Aneflous, a tailor, said even those whose homes were still standing were too scared to return because of the risk of collapse.
"Probably we will stay here for months or a year. People won't go home because their homes risk falling. God knows how long we will stay here," he said.
The International Federation of the Red Cross and Red Crescent Societies (IFRC) launched an emergency appeal on Tuesday to raise 100 million Swiss francs ($A174.8 million) to support victims.
"In this appeal, we are seeking 100 million CHF to be able to deliver on the most pressing needs at this time," including water, sanitation and shelter, Caroline Holt, global director for operations at IFRC, told reporters in Geneva.
"We need to make sure that we avoid a second wave of disaster."
The epicentre of the quake was about 72km southwest of Marrakech, where some historical buildings in the old city, a UNESCO World Heritage Site, were damaged. The quake also caused major damage to the historically significant 12th-century Tinmel Mosque.
More modern parts of Marrakech largely escaped unscathed, including a site near the airport earmarked for IMF and World Bank meetings, due to be held next month.
More than 10,000 people are expected at the meetings, which the government wants to go ahead, sources said.
Morocco has accepted offers of aid from Spain and Britain, which both sent search-and-rescue specialists with sniffer dogs, and from the United Arab Emirates and Qatar. Algeria said it had allocated three planes to transport rescue personnel and aid.
State TV said the Moroccan government might accept relief offers from other countries later.
Italy and Belgium joined France and Germany in saying they had offered to send in rescue teams but were still waiting for requests from Morocco.
Germany said it did not think the decision was political, but Italian Foreign Minister Antonio Taji told radio station Rtl that Morocco had chosen to receive aid only from countries with which it had close relations.
