Tornadoes & Tsunamis

I chose the Tri-State Tornado that occurred on March 18th, 1925, in Missouri, Illinois, and Indiana. This tornado was the deadliest in US history causing 695 fatalities. I picked a tornado-related event because even though I grew up on the edge of tornado ally in Saint Paul, Minnesota, I don’t know the science behind what causes them.

  1. I want to learn more about tornado science, and what sets apart a regular storm and a storm that has tornadoes.
  2. I want to have a deeper understanding of the categorizing system and why some rankings are disputed after the event.
  3. I would like to learn more about detection and warning systems for tornadoes and how it has changed since the Tri-State Tornado of 1925.

My second topic is tsunamis and the 1958 Lituya Bay tsunami that occurred in Southeast Alaska on a narrow inlet. I chose this event because tsunamis have always interested me and I have a very limited knowledge of them.

  1. What is the difference between a tsunami and a megatsunami as the 1958 event has been categorized as?
  2. Are there areas prone to more destructive tsunamis than others, and are they mapped?
  3. What and why are there conflicting analysis for the cause of the tsunami.
