Can yelling start an avalanche?
Abstract: It remains a popular myth that avalanches can be triggered by noise. The pressure amplitudes caused by shouting or loud noise are at least about two orders of magnitude smaller (a few Pascal) than known efficient triggers. Triggering by sound can therefore be ruled out as a triggering option.
What country has the most avalanches?

What is a human triggered avalanche?
A disturbance that initiates fracture within the weak layer causing an avalanche. These are “human triggered” avalanches. In other words, weather adds stress to the snowpack until it nearly equals the strength of the snowpack.
Where was the largest avalanche in modern history?
Utah avalanche was largest in modern history. SALT LAKE CITY — The avalanche near Salt Lake City last year that carried enough rock, dirt and debris to bury New York’s Central Park under 66 feet of rubble was North America’s largest such disaster in modern history, according to University of Utah scientists.
What was the worst avalanche in Peruvian history?
However, this was just the beginning. Within the next few weeks, many other avalanches struck the area, with disturbingly high frequencies of snowfalls claiming several more thousands of lives. The worst natural disaster in the history of Peru occurred on May 31, 1970, and is known as the Ancash Earthquake, or the Great Peruvian Earthquake.
