A new study has produced the first analysis of seismic echoes from hundreds of earthquakes at once, revealing widespread structures at the core-mantle boundary. Previous studies were limited to analysis of single earthquakes, providing only a narrow window into the structure deep inside the Earth. This study enables a much wider view than ever before, revealing new, unexpected features and expanding the size of a previously known feature beneath Hawaii.
