Dua Quake-Catcher peserta Jaringan dirasakan dan mencatat besarnya kemarin 4.0 gempa di Yorba Linda, California (selatan Cal, tenggara dari Los Angeles). You can view some of the data at this link. Mereka hanya sekitar 4 km / 2.4 mil dari pusat gempa, so it was a good test of QCN and the JoyWarrior USB sensors! Happily everyone is OK with just a few plates shaken up etc.
