What measurements is used to determine the strength of an earthquake?
There are 2 ways.Richter scale. This is an objective method, and is a scale of 1-10, each 0.1 increase in size is a 10 fold increase in power. (it is only possible, even with a mega-thrust quake to reach 9 on the Richter scale). This is the most accurate and commonly used scaleMercalli Scale. This is a subjective scale, and the reading is based on the damage done by the earthquake. It is a scale of roman numerals between 1-14.
How does an earthquake impact the natural environment?
In an earthquake the plates on the earth move and if they scrape past each other then a shock wave will be generated. If the crash into each other then they can sometimes form mountains and also let out a shock wave also one plate is forced under the other and that rock is melted down. If they pull apart then that also creates a shock wave and the gap left is filled with magma and forms a new part of the plate. Also it depends on the damage done to the things around it as to what is done to the environment.Well usually the normal happens, but if the earthquake is REALLY strong, it may start squirting out lava.

How big does the rictor scale reach?
The Richter scale does not have a maximum limit. It is a logarithmic scale that measures the magnitude of earthquakes, with each whole number increase representing a tenfold increase in measured amplitude. The largest recorded earthquake measured a magnitude of 9.5.

How long did it take 1960 Chile tsunami to reach Hawaii?
Ten Minutes in whole- which is pretty long for an earthquake as the one in 1989 lasted only fifteen seconds- and that was on the Richter scale about 7.1. The aftermath lasted a lot longer than ten minutes though, Valdivia still hasn't fully recovered from its "earthquake" shock.
Is Chile's earthquake bigger than Haiti's?
Yes and No. The Feb 27 Chile quake released much more energy( 8.8 on the moment magnitude scale) while the Jan 12 2010 Haiti quake released 7.0 but the Haiti quake killed over 210 000 people while the Chile quake death toll will perhaps reach 1000.

What is known as a seismic sea wave?
A seismic sea wave is commonly known as a tsunami. It is a series of ocean waves generated by a sudden displacement of the ocean floor, typically caused by an underwater earthquake, volcanic eruption, or landslide. Tsunamis can travel long distances across the ocean and cause widespread destruction when they reach land.
