History of Earthquake in Timeline

An earthquake is the shaking of the Earth's surface caused by a sudden release of energy in the lithosphere, generating seismic waves. These events vary in intensity, from imperceptible tremors to catastrophic upheavals capable of causing widespread damage and displacement. Seismic activity measures the frequency, type, and magnitude of earthquakes in a given area over time, while seismicity quantifies the rate of seismic energy release per unit volume at a specific location.

In 1988 Saguenay earthquake and the 1946 Vancouver Island earthquake, Canada had the second highest area affected by landslides with 66,000 km.

1995: Kobe earthquake

The memory of the great city of Kobe laid waste in 1995 shapes the portrayal of earthquakes in modern popular culture.

Aftershock: Earthquake in New York, released in 1999, is a story about earthquakes that generally begin with the disaster and focus on its immediate aftermath.

2001: 2001 Kunlun earthquake

The unusually wide zone of damage caused by the 2001 Kunlun earthquake has been attributed to the effects of the sonic boom developed in supershear earthquakes.
