6.3 Magnitude

The Christchurch earthquake that occurred in 2011 had a magnitude of 6.3. It caused widespread damage to buildings, infrastructure, and resulted in numerous casualties. The overall impact was significant due to the shallow depth of the quake and its proximity to urban areas.
The depth of focus of an earthquake with a magnitude of 7.2 can range from 10 to 700 kilometers below the surface of the Earth. At this depth, the earthquake originates within the crust or upper mantle, releasing energy that can cause significant shaking and damage near the surface.
No, the depth of focus of an earthquake does not directly determine its intensity. The intensity of an earthquake is primarily influenced by the earthquake's magnitude and the distance between the epicenter and populated areas. The depth of focus mainly affects the distribution of seismic waves and can influence the shaking intensity experienced at the surface.

Deep focus earthquakes can occur at depths ranging from 300 to 700 kilometers below the Earth's surface, with some reaching depths of up to 700 kilometers.
A tsunami did occur after the Christchurch earthquake, but it was relatively small and localized. The earthquake did not generate a large enough displacement of water to create a significant tsunami. Additionally, the orientation of the fault line and the shallow depth of the earthquake further limited the potential for a widespread tsunami.
The Christchurch earthquake happened on February 22, 2011. It was a devastating earthquake that caused significant damage and loss of life in the city of Christchurch, New Zealand.
The earthquake in Christchurch, NZ on the 22nd of February, 2011 was located just 4 or 5km underground. To put this in perspective, the quake in September, located near Christchurch was twice the depth, 10km below ground. So although the quake may have been 6.3 on the Richter Scale, it was a lot shallower than the one in September (7.3 on the Richter Scale), did a lot more damage and took many, many more lives. Hope this helps.
