how do scientist predict events?

Question

like how predict earthquakes, tsunami ,tornadoes, and etc

Answer 1

They can only predict where earthquakes are likely to occur, and the tsunami after the quake that cause it has happened. For tornadoes, they only know what weather condition give rise to them and send out warnings. They do better with large storms and have computer codes that can predict the path for days, but with decreasing accuracy as the prediction period increases. They are very good at eclipses. It depends on how simple the physical laws that govern the event are and how well they can be described by equations.

Answer 2

Actually, they can't. The new ice age didn't happen in the '70s. Mt. St. Helens didn't blow up until it wanted to. Tornados form very fast from not much. The earthquake causing the Tsunami was a surprise. Global warming is a chicken little paranoid fantasy.

Answer 3

By observing events that have already occurred and developing theories to explain these occurrences. The theories typically provide a calculation method which applies to similar events. Example: calculations about the activity of neutrons in uranium 235 indicated that if a large enough piece of it were assembled, it would explode. The theory was tested over Hiroshima at the end of World War II, and was found to be correct.

Answer 4

Process of deduction based up either trial and error or past events.
