Settlement Survival/Random events

Look at the timeline at the top right of the screen to see when events will happen.

Random Events come at random times. Most are problematic, but some are beneficial.

The requirements to having such a random event occur are based on time (beyond a certain year), and being larger than a certain population size.

Different events have different requirements for spawning, and are listed below:

Year	Settlement must be past this year number for the disaster to appear.
Population	Settlement must have more than this number of citizens for the disaster to appear.
Appears On	Some disasters only appear in certain seasons.
Length	How long the disaster lasts.
Spawn rate	A numerical value in the game files indicating the likelihood of the disaster occuring.

There are also smaller random events that occur throughout the year. A few require players to click on notable items, such as boxes floating down the river, or a particularly large tree, in order to trigger the event.

Tornado

Year	10+
Population	100+
Appears On	At any time
Duration	Unknown
Spawn rate	15

Tornadoes can happen in any day or month of the game. The most that they can spawn is once every 3 years and only have 1 at a time. You are given an alert in the news feed when one begins, your game speed will also be slowed to 1x at this time.

The tornado always spawn on the edge of the map and has a slow movement speed. The angle will not change much and you should be able to predict what is in its path. Any building in the path, that doesn't have the proper upgrade, will be destroyed, losing all of its contents, and upgrades. Any citizens under the twister will also be killed. Depending on the path, you may want to quickly upgrade some key buildings to prevent them from being destroyed. Also calling for everyone to run to the mountain side shelter could save some lives.

Snowstorm

Year	5+
Population	50+
Appears On	Winter
Duration	90 days
Spawn rate	20

Blizzards can happen once every 3 years and only starts between day 211 and 360. Another requirement for the event to trigger, is your settlement must have at least 50 citizens. When the blizzard starts, you will be alerted in the news feed, the game speed will go to 1x and audio will change to be that of a blizzard.

During the blizzard the temp drops to -70f and all crops quit proving yields. Workers also take a work speed debuff. The temperature drops to -70F and all crops quit producing yields. During this time citizens lose their warmth extremely quickly. Those without clothes will even freeze faster. When a citizen is cold they will attempt to warm up at a Boiler building, their house, or another citizen's house. All three of these require a fuel source for the citizen to warm up properly. The main cause of death during blizzards will be freezing, starvation, and dehydration, so be sure to have plenty of fuel, food, water and clothing stored up.

Fire

Year	3+
Population	20+
Appears On	At any time
Duration	30-45 days
Spawn rate	20

For a period of days, fires can randomly break out throughout your village. The fire will spread from building to building and can quickly destroy your village if you don't have Big Wells near by. Up to 50 citizens will assist in putting out the fires but your fire count can spread way behind that. The best protection against fires is to have some Big Wells spread throughout your village.

During a Plague many citizens will hit with the Plague. Just like any other disease they will spread it to other citizens. They will attempt to get treated in Clinics and Hospitals but while heading to the buildings they pass it along to others. Unknown protection at this time.

Plague2

Year	6+
Population	Any
Appears On	Summer
Duration	120 days
Spawn rate	20

It is hot outside. The rivers dry up, which means no river based workplaces will work. Farms also have reduced output and other debuffs may be present. Best way to prepare is by having a good store of food and some non-water based production buildings.

Sandstorm

File:SetSur Sandstorm.jpg
Year	3+
Population	100+
Appears On	Any time
Duration	120 days
Spawn rate	15

Sandstorms operate similarly to tornadoes, but are far less destructive. After spawning, it will move across the map, damaging trees, buildings, and people that are in its path. Having nearby trees will help reduce the effects of a sandstorm, so keep some greenery nearby as a shield.

Spawn rate	20

Also referred to as Worms, animal plagues wreak utter havoc in your pastures, causing animals to die - directly affecting meat and animal byproduct production.

Immigrants

Appears On
Duration
Spawn rate

These immigrants will request permission to settle in your town. Early game, this will be a good way to grow your town's population.

Ensure you have enough food, water, spirits, and other resources in order to support your new burgeoning population.

As the number of immigrants is usually around eight, having a boarding house constructed is an important buffer to allow immigrants to stay at, and give your other citizens the chance to build proper housing. Once proper housing is constructed, the immigrants will move to the new houses on their own.
