Global variations of Earth's 520- and 560-km discontinuities
  1. We perform a global survey of the 520- and 560-km mantle discontinuity by analyzing SS precursors.
  2. Our observations confirm the global existence of the 520-km discontinuity.
  3. Depth variations of the 520-km discontinuity correlate with the mid-MTZ temperature.
  4. Compositional heterogeneity also contributes to the 520-km discontinuity topography.
  5. A 560-km discontinuity is sporadically detected in subduction zones and mantle upwells.
  6. The existence of the 560-km discontinuity may imply localized Ca-enrichment in the mid-MTZ possibly related to the recycling of oceanic crust.

Collapse and earthquake swarm after North Korea's 3 September 2017 nuclear test
  1. We present high-precision locations and detailed source information of four small seismic events following North Korea’s 2017 nuclear test.
  2. The first event is an on-site collapse 440 m northwest of the test site and best explained by a near vertical single force.
  3. The later events are an earthquake swarm located 8.4 km north of the test site with a focal depth of at least 2.4 km.
