Safety in Taiwan:Taiwan is generally a super safe country. You will see that there are cameras everywhere, and that deters a lot from breaking the rules. In addition, it is a country in which domestic employment is highly protected, which is why it has super low unemployment rates. If you leave something on the subway or in a taxi, it will most likely be returned and put in a safe place.
The only precautions you should take are with cars. Here pedestrians have no priority, and unless there is a red light for them, they will not stop to let you pass even in a crosswalk.
And then there are earthquakes and typhoons (hurricanes). The former can occur at any time, although they are more frequent and stronger on the east coast of the country. If you notice one, make sure there is nothing around you that could fall on you, and protect your head and neck, which are the biggest cause of earthquake injuries in Taiwan (buildings are prepared not to fall, find a clear room or get in under a table). If you are on the street, go to an open park where there are no trees or anything that can fall on you.
In the case of typhoons, the season in which they usually occur is from July to September. If you have bought a local SIM card when you arrive in the country, you will receive government alerts in case one is approaching. In this case, follow the instructions of the authorities and do not leave the house during the day / days that the typhoon lasts.
