Hello.
On November 1 after 6 years in Big Sur, I decided to pack up and moved to Alaska with my 2 kids and dog. I chose Russia as my country  because of their history with Alaska. Our boarders are closer than the distance to California.
Define the difference between hazards, disasters and catastrophes:
Hazards are things that take place in nature that cause harm such as earthquakes, hurricanes, sinkholes, hail storms, wildfires, and  threats to human life and property.  Keep in mind that one natural hazard can lead to another. For example, an earthquake can cause a tsunami.
Natural disasters are slightly different. They are the effects of natural hazards on humanity which occur over a specific time and defined area. Criteria  to be considered a natural disaster are :  10 or more people are killed; 100 or more people are affected; State of emergency is declared and international assistance is requested. Only 1 of these need to apply.
A catastrophe is a massive disaster and takes years of recovery efforts. A great example is hurricane Katrina.
The following are great videos of  different disasters
