A few general observations-

Post-disasters:

In the immediate aftermath, information is a hot commodity. Generally, people want to know how "bad" and how extensive the damage is, how it is being covered in the news media, and what relief efforts are being undertaken. Specifically, people want to know where they can get help and what kinds of assistance are available, what stores, roads and government facilities are or will be re-opening and when, and they especially want to know the status and location of family, friends and pets. They also want to know the status of their own homes, neighborhoods and workplaces. Lastly, they want to let others know that they are okay.

So if you have internet access and/or a satellite phone, you, too, can be a hero! Radios with a speaker loud enough to be heard by a group, and outside newspapers are both informative and a useful diversion. Even personal digital photos taken on your cell phone or camera, if you've been able to get out and about more than others, will be of great interest to those who haven't been out.

Getting clean is always a morale boost. A hot shower and a change into a fresh uniform puts everybody in a better mood, as does any sort of decent, fresh, non-MRE meal. Our logistics people usually rig up a shower pretty quickly, and a washer and dryer somehow usually "magically" appears, or arrangements are made for laundry runs at some point, for us. Showers and laundry usually become available at shelters, too, although patience and organizational oversight is usually required if demand outpaces supply.

Clean and sanitary toilet facilities are also essential to make people feel more nearly normal. But these will quickly deteriorate if very frequent cleaning isn't done, because some people are always going to be disgusting pigs, regardless of the circumstances.

If you have or can arrange to provide these things, you'll go a long way toward improving people's morale.

Things people tend to want or run out of after a disaster:
CASH, more CASH
Tobacco and lighters
Plastic garbage bags
Paper towels, plates, etc.
Batteries
Cleaning supplies -mops, buckets, shovels, brooms, etc.
Cleaning agents - disinfectant sprays, bleach, soaps, cleaners, etc.
Personal hygiene items, feminine needs products, and baby supplies.
Work gloves, etc.
Basic demolition/mitigation supplies - tools, plywood, tarps, etc.

During a survival emergency:
A photo of family or loved ones has long been recognized as a morale booster and motivator, as has a Bible or other religious material for believers.

Having a plan that is well thought out, clearly communicated and credible, is a the first step to maintaining good morale.

Setting specific achievable tasks for all who are able, like gathering firewood or collecting water, keeps people busy and allows them to make a noticeable contribution to the group. Keeping some sort of regular schedule of activities and tasks, or duty roster, fights lapses into lethargy and despondency.

It may seem hokey, but group singing has scientifically documented benefits for morale and group cohesion. Group prayer and conversation are good, too. Only do not let anyone avoid or be excluded from these. Also, do not allow these to deteriorate into gripe sessions, finger pointing, recriminations, if-only or hopelessness.
