Lol I don't know WHAT happened in the previous question. Everyone except got it wrong -- the answer is B since it is a complex list. And everyone was so confident in it being D, kinda crazy lol.
Anyway, new:
A) the Cascadia Subduction Zone increased from 2019 and, in 2020, recorded more microearthquakes per month than the New Madrid Seismic Zone but fewer than the San Andreas Fault.
B) the San Andreas Fault decreased from 2019 and, in 2020, recorded fewer microearthquakes per month than the Cascadia Subduction Zone but more than the New Madrid Seismic Zone.
C) the New Madrid Seismic Zone decreased from 2019 and, in 2020, recorded more microearthquakes per month than in 2018 but fewer than in 2019.
D) the Cascadia Subduction Zone decreased from 2019 and, in 2020, recorded more microearthquakes per month than the New Madrid Seismic Zone but fewer than the San Andreas Fault.
