Good morning geo friends! The U.S. Geological Survey (USGS) has recently updated their U.S. National Seismic Hazard Maps, which reflect the best and most current understanding of where future earthquakes will occur, how often they will occur, and how hard the ground will likely shake. While earthquakes remain hard to predict, the USGS hopes to understand how

The Alpine Fault forms the plate boundary in New Zealand's South Island, and is a very significant fault on a global scale. It last ruptured in 1717 AD and appears to produce large earthquakes on average every 330 years. Its next rupture has a high probability (28%)  of occurring in the next 50 years.Each time the Alpine Fault ruptures, there is roughly 8 metres of sideways movement and about 1 to 2 metres of vertical uplift on the eastern side. These magnitude 8 (M8) earthquakes can [...]

Lots of earthquakes recently and several more today. I'm disappointed that the recent M4.3 does not have a fault-plane solution.  Judging from the weak ground motions, I think this is another one of those tension 'back-slip' earthquakes, responding to the main mechanism.  Overall, the main mechanism responds to the high horizontal stress by contracting, and this allows the back-slip.
