Consider the following statements regarding Glacial Lake Outburst Floods (GLOFs) in the Hindu Kush Himalaya (HKH) region:

Statements

1. Moraine-dammed glacial lakes are particularly susceptible to outburst events because moraines are unconsolidated glacial debris that can be breached by triggers such as ice avalanches or intense rainfall.
2. Ice avalanches are a less significant trigger of GLOFs compared to intense rainfall, which accounts for the majority of such events in the HKH region.
3. The concentration of GLOF events during summer monsoon months reflects a compounding of thermal and precipitation drivers — higher temperatures accelerate ice melt and destabilise ice masses, while heavy rainfall saturates moraine structures.
