- Dr Ursula Cochran is an earthquake geologist from GNS Science. In this AF8 Science series, she explains the evidence for past large earthquakes on the Alpine Fault.
Well done Ursula, I'm surprised how few people have viewed this video, and how few have given it a thumbs up. Keep up the good work. I flew commercial aircraft into Milford from Wanaka for 6 years and would do a small 90 deg turn over lake McKerrow to show the line of the fault. Its magnificent country.
Thank you for keeping us informed about the earthquake history and details in the Alpine Fault. Your work is much appreciated.
Thanks so much for such a great presentation.👍👍👍
Well presented. Really interesting. Thanks.
Excellent video, thank you for sharing and making us aware of these faults, I will add it to the others around the world that have the potential to rupture in my life time. I like geologists they are always polite and say it's my fault.
Thanks👍

We need a small fleet of airships as all roads will be out for months
put two poles apart the fault line with a very strong and tight rope of steel with scale so every moments are visible in millimetres scale
When will the data on the northern lake sediment records be published?
Has anyone else noted that the patterns of quakes moved northward, now some strong close tight clusters in various places White Island and now near Haast. Does anyone have a theory on the causes of the tight clusters.
After the 2016 Kaikoura earthquake the Clarence river was dammed. Is it still dammed?
No. It broke through or found a way around without a dam burst within hours.
i will give an idea so we know next date of earthquake before the time so we got more time to escaped
What is the speed at which the fault ruptures? I have seen estimates of 3 to 4 km per second. Would this not make a 7m horizontal and a 1m vertical movement virtually instantaneous?
That is how fast a tear forms and moves along a line then the plates jostle past each other. 7 meters and 1 meter is the total after the shaking stops. Other quake are plates pushing straight on and those ones are all sudden spring back uplift with no side movement. California/Oregon Cascade Fault is expected to maybe an uplift of as high as 100 feet for 100s on miles.
@@MrBonners Thank you.
all your knowledge is limited without knowing about distance wise correlation between mahakala mandir of ujjain in India
this fact will gives whole universe a new kind of insight
if you know a decade ago that earthquake occurred then will you leaves the places
