 Earthquake K-12 Experiments & Background Information
Earthquakes occurring at boundaries of tectonic plates are called interplate earthquakes, while the less frequent events that occur in the interior of the lithospheric plates are called intraplate earthquakes.
Some earthquakes are the result of a number of anthropogenic sources, such as extraction of minerals and fossil fuel from the Earth's crust, the removal or injection of fluids into the crust, reservoir-induced seismicity, massive explosions, and collapse of large buildings.
Earthquakes have also been known to be caused by the removal of natural gas from subsurface deposits, for instance in the northern Netherlands.

 earthquake
Earthquakes occur every day on Earth, but the vast majority of them are minor and cause no damage.
Earthquakes, especially those that occur beneath sea- or ocean-covered areas, can give rise to tsunamis, either as a direct result of the deformation of the sea bed due to the earthquake, or as a result of submarine landslips or "slides" indirectly triggered by it.
Some earthquakes are caused by the movement of magma in volcanoes, and such quakes can be an early warning of volcanic eruptions.

Earthquakes occur where the stress resulting from the differential motion of these plates exceeds the strength of the crust.
Most earthquakes are tectonic, but they also occur in volcanic regions and as the result of a number of anthropogenic sources, such as reservoir induced seismicity, mining and the removal or injection of fluids into the crust.
Deep focus earthquakes, at depths of hundreds of kilometres, are possibly generated as subducted lithospheric material catastrophically undergoes a phase transition since at the pressures and temperatures present at such depth elastic strain cannot be supported.

 Great Chilean Earthquake - Wikipedia, the free encyclopedia
The Great Chilean Earthquake or Valdivia Earthquake (Terremoto de Valdivia in Spanish) of May 22, 1960 is the largest magnitude earthquake recorded since seismographic monitoring began.
The total number of fatalities from the earthquake and tsunami was estimated to be 6,000.
Despite the record strength of the earthquake, more people were killed by tsunamis than by the earthquake.

 Earthquake
Most large earthquakes are accompanied by other, smaller ones, known as foreshocks when they occur before the principal or mainshock and aftershocks when they occur following it.
The source of an earthquake is distributed over a significant area -- in the case of the very largest earthquakes, in excess of a thousand kilometres -- but it is usually possible to identify a point from which the earthquake waves appear to emanate.
A rare few earthquakes have been associated with the build-up of large masses of water behind dams, such as the Kariba Dam in Zambia, Africa, and with the injection or extraction of fluids into the Earth's crust (e.g, at certain geothermal power plants and at the Rocky Mountain Arsenal).

 Important.ca. Asia Earthquake, Tsunami Information Resource
Since 1900, the only earthquakes recorded with a greater magnitude were the 1960 Great Chilean Earthquake (magnitude 9.5), the 1964 Good Friday Earthquake in Prince William Sound (9.2), and the March 9, 1957 earthquake in the Andreanof Islands (9.1).
The earthquake itself (apart from the tsunamis) was felt as far away as Bangladesh, India, Malaysia, Myanmar, Thailand, Singapore and the Maldives.
The shaking of the seabed by the earthquake displaced massive volumes of water, resulting in tsunamis that struck the coasts of the Indian Ocean; the deadliest tsunamis by far in all of recorded history.

 Greatest Earthquake
The honor of greatest earthquake of all time goes to the 1960 Chile earthquake because scientists were able to catch this one on tape.
The instruments that seismologists use to measure earthquake magnitudes are designed to detect the amount of energy released by the movement of the ground during a quake.
In the case of the Chile earthquake, the amount of energy released during the quake, not the number of human deaths and damage to structures, earned it the title of greatest.

The 2004 Indian Ocean Earthquake was an undersea megathrust earthquake of moment magnitude 9.0 that struck the Indian Ocean off the western coast of northern Sumatra, Indonesia on December 26, 2004 at 00:58:53 UTC (07:58:53 local time in Jakarta and Bangkok).
It was the largest earthquake on Earth since the 9.2-magnitude Good Friday Earthquake which struck Alaska on March 27, 1964, and the fourth largest since 1900 (tied with a 1952 earthquake of 9.0 magnitude in Kamchatka).

There is some intriguing research about whether large earthquakes are associated with ionospheric changes caused by electromagnetic signals released by the crushing of rock crystalline structures.
Best approach might be to pick a recent earthquake then check the SID data from stations around the world to see if any changes were noticed at, before, or after, that time.
