Long-term post-fire problems with debris flows and pollution...
If your immediate area or part of your water catchment has been burned over, please be on alert.
Debris flows from 'heat-sealed' or 'destabilised' slopes may be heading your way. Or may contaminate your water supply. Or rain / thaw simply runs off without recharging shallow aquifers such as river terrace gravels.....
Scary footage of 'local' debris flow:

On a bigger scale, when the mountainside comes calling...

Very relevant to US post-fire scenario...

A lot of advice common to snow avalanche strikes on buildings, but with a hard edge. Note how occupants may be trapped by security grilles. Even Alpine 'chevron' fencing / guard walls may not suffice...
And, if you or your access/egress routes are near a similar lake to this, use due care, please.

Remember Lituya Bay, https://en.wikipedia.org/wiki/1958_L...nd_megatsunami
also Vajont Dam https://en.wikipedia.org/wiki/Vajont_Dam
Australia studying toxins and pollutants leaching from burned areas several years along: their 'big burn' was ~2016, but they'll face problems for a decade or more.

Stay Safe, Stay Well, Don't Let The 'Second Wave' COVIDiots Win.
