🌟OPEN ACCESS🌟EQS-denoiser is a new deep-learning based model trained on earthquake and noise from Switzerland. Find out how it compares to other models in #BSSA. ⚒️

buff.ly/WZzNUHz

In a new #SRL paper, scientists explore the 2020 magnitude 5.1 Sparta, North Carolina earthquake sequence — an extremely shallow event. They found that the sequence originated from a shallow, weak layer containing a network of intersecting fractures. ⚒️
