Well the 1946 earthquake to my knowledge was 8.0 in magnitude but the 20010 was was only 7.0 so in fact the 1946 earthquake was stronger, but the media coverage may not have been as large which is why people may be under the illusion that the 2010 earthquake was stronger, it is one of the positive consequences of the internet transmitting information that we can learn about these disasters quicker to send help especially to less economically developed countries.
My understanding of the magnitudes of earthquakes is that each decimal point is equal to a magnitude of strength 10x more than the previous number. Example would be that a 4.2 earthquake is 10x stronger than a 4.1 earthquake. Therefore, a magnitude 8.5 EQ is 100x stronger than a 7.5 EQ.

According to the US Agency for International Development (USAID) the US has so far (as of the 18th of Jan 2010) pledged $114,482,301 to the aid effort in Haiti. Please see the related links for details on a breakdown of this spending and updated information.
The Chile earthquake at 8.8 was about 100 times stronger than the Haiti earthquake at 6.8. The Richter scale is logarithmic. The difference between the earthquakes is 2.0, which is the logarithm of 100.
If you mean how stronger a 7.9 earthquake is then a 4.6 earthquake, then a 7.9 earthquake is way stronger. It can take down buildings but then again so can a 4.6, still you've sorter got you're answer. But the 7 in 7.9 means 700 and the 0.9 is 90 so baisically your question is: How stronger is a 790 earthquake from a 460 earthquake?
A magnitude 8 earthquake is 1,000 times stronger than a magnitude 6 earthquake in terms of energy released. It can cause significantly more damage and have a larger impact on structures and the environment.
A LOT stronger. The force of an earthquake is expressed using a log 10 scale of energy. A 5.0 earthquake is 10 times stronger than a 4.0, a 6.0 is 10 times stronger than a 5.0, and so on. 9 is the highest number on the scale, and would be a "Great" earthquake, as opposed to minor, moderate, strong or major. Total destruction of man-made structures, etc.
An 8.3 earthquake is significantly stronger than a 6.6 earthquake. Each whole number increase on the Richter scale represents a tenfold increase in the amplitude of seismic waves, meaning an 8.3 earthquake releases exponentially more energy than a 6.6 earthquake.
Because of the Richter Scale's logarithmic properties, a number 5 earthquake is 100 times more severe than a number 3 earthquake.
The cost to fix the damage from Haiti's earthquake in 2010 was estimated to be around $7.8 billion.
An 8.8 earthquake is approximately 63 times stronger than a 7.0 earthquake in terms of energy release. The Richter scale is logarithmic, so each whole number increase represents a tenfold increase in amplitude and a 31.6 times increase in energy release.
because of earthquake in 2010 - in pounds 45 billion and in 2011- 78 billion but still repairing
An 8.0 magnitude earthquake is significantly stronger than a 4.0 magnitude earthquake, approximately 10,000 times more powerful in terms of energy release. The Richter scale is logarithmic, meaning each whole number increase represents a tenfold increase in measured amplitude and about 31.6 times more energy release. Thus, an 8.0 earthquake can cause much more severe damage than a 4.0.
A 7.1 earthquake is approximately 10 times stronger in terms of energy release compared to a 7.0 earthquake. The Richter scale is logarithmic, meaning each whole number increase represents a tenfold increase in amplitude and roughly 31.6 times more energy released.
The magnitude of an earthquake is measured on a logarithmic scale, so a magnitude 7.0 earthquake is 10 times stronger than a magnitude 6.0 earthquake in terms of the energy released. This means that the amplitude of ground shaking in a magnitude 7.0 earthquake would be significantly greater than in a magnitude 6.0 earthquake.
