alpine fault earthquake

Although the Alpine Fault accommodates a substantial amount of interplate slip, a significant proportion is distributed to the east within and east of the Southern Alps. Geologists and authorities are racing to quantify what might happen, and how they might respond in the event of the next one, likely to occur some time in the next 50 years. This fault has ruptured four times in the past 900 years, each time producing an earthquake of about magnitude 8. "However, the plates are locked and when they overcome these barriers, they produce large but infrequent earthquakes. Ms Goyal continued: "Through road shows in the Southern Alps and teaching modules on physical geography for middle and high school students, AF8 aims to increase public awareness of natural hazard risk so that communities might develop a resilience and adaptation plan down the road.
