The Annapurna region sees the highest number of trekkers, followed by the Everest region.
The April 25 quake had its epicentre in Gorkha to the west of Kathmandu, but it shook mountains as far away as Everest to the east.
That quake ruinously rattled mountains mainly in the Langtang valley, where entire villages were buried under avalanches and landslides and debris killed nearly 200 people including foreign trekkers.
The main quake zone also shook many mountains in the Annapurna region, where landslides have continued and one of them even blocked a major river on Sunday.
The biggest aftershock - a 7.3 magnitude quake on 12 May - had its epicentre to the northeast of Kathmandu where there are popular trekking regions including the Rolwaling and Helambu.
Geologists say the quakes triggered more than 3,000 landslides in the affected areas and the upcoming monsoon could worsen conditions.
"The reason why the mountains remain unstable is that earthquakes cause intense shaking of the landscape, which damages the rock and soils on hillsides," says Prof Alex Densmore from the Institute of Hazard, Risk and Resilience at Durham University in the UK.
"This means that even hillsides that did not fail during the earthquake are more damaged, and thus more prone to failure, than they were before 25 April.
"In some cases this damage may be visible at the surface in the form of cracks or fractures in the ground, but this is not necessarily the cas
