1) "Pheriche was destroyed before our eyes"

Non EBC-trek area:

4) "Langtang appears to have been very badly affected - including the road to get there."

"The whole of Langtang village was cleared, nothing remains there. No more guest houses, everything was wiped out by the avalanche"

"The entire village (Langtang), which includes 55 guesthouses for trekkers, was wiped out by the avalanche, officials said."

"The village of Langtang was completely buried by an avalanche that came from thousands of feet above on the southern slopes of Langtang Lirung and Langtang II. Smaller settlements on the outskirts of Langtang, such as Chyamki, Thangsyap, and Mundu were also buried."

5) "It’s difficult to assess the extent of the damage in the Khumbu. In Thame, which appears to be one of the worst hit villages, estimated that nearly 100 percent of the structures were destroyed. Looking out, metal roofs are still up, but all interior walls are out"

6) Other Khumbu villages reportedly hit hard include Khumjung, one of the traditional homes of Everest Sherpas.
