Responsibility for affiliations ultimately rests with the author, although Lithosphere may request changes be made to countries listed in affiliations to ensure consistency across published output (for indexing and discovery reasons). Earthquake early warning (EEW) systems are crucial for mitigating seismic hazards. Current EEW algorithms predominantly rely on seismic data (Allen and Melgar, 2019) and can be classified into three main categories: point‐source, finite‐fault, and ground‐motion‐model based.Multiple algorithms and various data types are often integrated into one system to enhance accuracy.

Based on the abundance of pyroxenites in the melting region of subduction zones as well as the lower solidi temperatures and higher melt productivities of these lithologies compared to peridotite ( Lambart et al., 2013 ), preferential melting of pyroxenite may supply disproportionate volumes of magma to the arc budget, especially at thick ...Geology has been the Web of Science's #1 ranked "geology" journal for 15 years in a row.
