ShakeNZ Examples

The images below show actual seismic events in New Zealand as they would have appeared in ShakeNZ.

• A magnitude 5.5, 30 km deep near Wellington.
• A magnitude 5.9, 100 km deep near Murchison.
• A magnitude 4.5, 15 km deep near Auckland.
• Non-Earthquake Cases.

Magnitude 5.5, 30 km deep near Wellington

Moderate, shallow earthquake - felt regionally, with minor contents damage possible near the epicentre:

Magnitude 5.9, 100 km deep near Murchison

Moderate, deep earthquake - felt over a wider area than above but not as strongly. No damage expected:

Magnitude 4.5, 15 km deep near Auckland

Light, shallow earthquake - felt only locally, but in this case by many people. No damage expected:

Non-Earthquake Cases

Examples:

• A data outage in the lower North Island.
• A false strong motion trigger near Christchurch. (Seismic events normally trigger several detectors at once, whereas objects dropped on or near them will cause only that one detector to transmit data).
• Seismic noise on White Island.
