Earthquakes Vs. Hurricanes


Typhoon
Earthquake

Predictability
Depend on determining the position and strength of high- and low-pressure areas, and predicting how those areas will change during the life of a tropical system. The deep layer mean flow, or average wind
Changes in seismic pressure and shear waves passing through rock
Frequency
The strongest earthquakes (8.0 magnitude) happen once a year while the weakest ones (2.1 magnitude) happen 1.3 million times a year.
About 79 typhoons form globally
Duration

An 8.0 magnitude earthquake can be felt for 30-40 minutes from hundreds of miles away
Typhoon Yolanda, one of the strongest typhoons to make landfall, lasted for 9 days.

According to this map Hurricanes can be found on and near the equator. There are hurricane zones in the Pacific Ocean. There are also hurricane zones around the Caribbean, Central America, and the eastern coast of America.

Earthquakes usually occur on fault lines. These earthquakes happen where the tectonic plates meet and converge into each other.

Both earthquakes and hurricanes affect shore lines. Both are common in South East Asia. Both occur due to pressure changes. Earthquakes are cause by changes in pressure between plates. Hurricanes are caused by changes in air pressure.


Earthquakes

Hurricanes
Significant terrain alterations
Haphazard destruction of human settlements
Unstable land collapses
Almost everything destroyed by wind and water
Can damage electric lines causing fire
Social order deterioration regarding Katrina

Enables people to be forewarned more easily
