Banks Peninsula is a complex of extinct shield volcanoes resulting from intraplate or "hotspot" volcanism 8-11 million years ago, built mainly from alkali-basalt lavas. In some shield volcano eruptions, basaltic lava pours out of a long fissure instead of a central vent. This appears to have occured in the case of the craters that eventually eroded to form the Lyttleton and Akaroa Harbours. The Lyttleton volcano formed first (11-10 million years ago) and the Akaroa volcano later (9-8 million years ago). The Banks Peninsula complex formed at the margin of the area affected by compressional tectonics on the Pacific/Australian Plate boundary. Eruptions on the Peninsula continued until about 6 million years ago, which coincides roughly with the epoch at which compressional tectonics became established in the Canterbury and Otago regions. Geologists therefore speculate that the onset of compressional tectonics (of the sort dramatically witnessed in Canterbury in 2010/2011) turned off the alkaline intraplate volcanism of southern New Zealand; i.e., it is the reason that these volcanos have been extinct for millions of years.

In seed banks which came first seed banks under mountains or seed banks in giant freezers?
Seed banks in giant freezers came first. The first seed banks were established in the 20th century to preserve plant genetic diversity. The concept of seed banks under mountains, like the Svalbard Global Seed Vault, came later as a backup measure to protect seeds from natural disasters and global crises.

What type of volcano is Christchurch?
Christchurch is not located on a volcano; it is situated in the Canterbury region of New Zealand, which is primarily characterized by sedimentary rock and not volcanic activity. However, the broader region of Canterbury has volcanic features, such as the nearby Banks Peninsula, which was formed by volcanic activity millions of years ago. The area around Christchurch is more known for its plains and river systems rather than active volcanism.
