Final answer:
The Great Alaska Earthquake of 1964 was a massive 9.2 magnitude earthquake, while the frequent seismic events experienced by Tom Gilson in Alaska are typically of much lower magnitude due to active plate tectonics in the region.
Step-by-step explanation:
To compare the earthquakes Tom Gilson experienced with the Great Alaska Earthquake of 1964, we must consider the scale, impact, and geological significance of each event. The Great Alaska Earthquake, also known as the Good Friday Earthquake, was a megathrust earthquake that occurred on March 27, 1964, with a magnitude of 9.2, making it the second most powerful earthquake ever recorded.
Seismic activity in the region, such as that experienced by Tom Gilson, might refer to the frequent earthquakes in Alaska due to its position along the plate boundaries, particularly in areas such as Mt. Denali which experiences around 600 seismic events per year.
However, most of these events are likely to be of much lower magnitude compared to the 1964 earthquake. The devastating effects of the Great Alaska Earthquake included ground shaking, tsunamis, and landslides, causing significant loss of life and damage to property.
