spreading as much as wide. Both scenarios are significant threats to life, property and infrastructure. Monitoring The United Nations has a series of monitoring efforts to help prevent death and destruction in regions that are likely to experience these events. The importance of this situation has magnified over the past century due to increased populations, and the increasing number of glacial lakes that have developed due to glacier retreat. While all countries with glaciers are susceptible to this problem, central Asia, the Andes regions of South America and those countries in Europe that have glaciers in the Alps, have been identified as the regions at greatest risk. There are a number of imminent deadly GLOFs situations that have been identified worldwide. The Tsho Rolpa glacier lake is located in the Rolwaling Valley, about northeast of Kathmandu, Nepal, at an altitude of . The lake is dammed by a high unconsolidated terminal moraine dam. The lake is growing larger every year due to the melting and retreat of the Trakarding Glacier, and has become the largest and most dangerous glacier lake in Nepal, with approximately 90 to 100 million m3 (117 to 130 million yd3) of water stored. Examples Asia India In June 2013 , Kedarnath in Uttarakhand witnessed flash floods along with a GLOF caused by Chorabari Tal, killing thousands of pilgrims, tourists and residents who came to visit the place. Pakistan Pakistan has more than 7000 glaciers, which is more than anywhere else in the world, except for the polar regions. As of 2018, more than 3,000 glacial lakes had formed in Gilgit-Baltistan, with 30 identified by the UNDP as posing an imminent threat of glacial lake outburst flooding. In 2017, a "Scaling up of Glacial Lake Outburst Flood Risk Reduction in Northern Pakistan Project" was continued. In 1929, a GLOF from the Chong Khumdan Glacier in the Karakoram caused flooding on the Indus River 1,200 km downstream (a maximum flood rise of 8.1 m at Attock). Bhutan GLOFs occur with regularity in the valleys and low lying river plains of Bhutan. In the recent past, flash floods have occurred in the Thimphu, Paro and Punankha-Wangdue valleys. Of the 2674 glacial lakes in Bhutan, 24 have been identified by a recent study as candidates for GLOFs in the near future. In October 1994, a GLOF upstream from Punakha Dzong caused massive flooding on the Pho Chhu River, damaging the
