There is no obvious similarity between the two earthquakes as they had differing causal mechanisms, occurred on differing types of tectonic plate boundaries between two different pairs of tectonic plates.
The two earthquakes occurred due to differing types of fault movement (thrust faulting in the Chilean quake vs strike slip faulting in the Haitian quake) and at two differing types of plate boundaries. In the case of the Chilean earthquake, this was at a convergent boundary where the Nazca oceanic plate is being subducted under the continental South American plate as opposed to the Haitian earthquake which occurred at a transform boundary between the Caribbean and North American plates which are both moving east but at differing speeds.
Also the earthquakes caused a significantly different number of casualties and fatalities (approx 230,000 dead in Haiti vs. approx 800 in Chile).
Please see the related links for more information about the two earthquakes.
It is impossible to determine how many earthquakes there have been in the past century. Earthquakes occur frequently all over the earth, including deep under the ground. Many of these may not be felt by people and barely register on seismic equipment, but they are still earthquakes.
No
A seismometer / seismograph.A seismograph measures and records the waves generated by earthquakes and similar seismic events.

long term earthquakes are earthquakes that are for a long period of time and short term earthquakes are when the earthquakes are for a short period of time
The two earthquakes occurred due to differing types of fault movement (thrust faulting in the Chilean quake vs strike slip faulting in the Haitian quake) and at two differing types of plate boundaries. In the case of the Chilean earthquake, this was at a convergent boundary where the Nazca oceanic plate is being subducted under the continental South American plate as opposed to the Haitian earthquake which occurred at a transform boundary between the Caribbean and North American plates which are both moving east but at differing speeds. The Haitian earthquake was also of lower magnitude (magnitude 7.0) than the Chilean earthquake (magnitude 8.8) however it caused more damage and led to a much larger number of injuries and fatalities due to the poor construction techniques used in Haiti. Please see the related questions for more information.
There have been a number of "famous" or perhaps "infamous" Chilean earthquakes, including the 1960 Valdivia Earthquake, which with a magnitude of 9.5 was the largest ever recorded by seismometer. Another was the earthquake that occured in February 2010 shortly after the devestating Haitian earthquake of January 2010. For more information, please see the related question and links.

One difference is: By the end of the year, 80% of the damage was either fixed or replaced, and Kobe did not take any donations that were offered to them. Haiti received £4.6 billion and still there is rubble taking up 40% of the country.
The Chilean earthquake was some 500 times bigger than the Haitian earthquake. The January 12th Haitian Earthquake was magnitude of 7.0 on the Richter Scale. The energy involved was equivalent to 32 million tons of TNT (about 2000 Hiroshima Bombs) The February 27th Chilean Earthquake was magnitude of 8.8 on the Richter Scale. The energy involved was equivalent to 15.8 billion tons of TNT. (about a million Hiroshima Atomic Bombs) Just a subnote one after shock of the Chilean earthquake at 08.01 GMT measured mag 6.9 on the Richter scale (26.8 milion tons of TNT or 1700 Hirsohima bombs)

They are both caused by earthquakes
They are similar because they both form volcanoes and earthquakes.
Both of these earthquakes occurred due to movement on a transform fault. In the San Francisco earthquakes, this movement occurred on the San Andereas fault and in Haiti this was caused by movement on the Enriquillo-Plantain Garden fault.
