This study reports on tremor along the Dead Sea Transform (DST) and a microearthquake on the Carmel-Fari'a Fault (CFF), both remotely triggered by the 2023 Mw7.6 Kahramanmaraş earthquake. The triggered events' location coincides with maxima of long-period velocity gradients. The DST tremor is strong and deficient in high-frequency seismic energy. Analysis of triggered tremor episodes suggests that tremor spectral fall-off rates are not universal. Two models—one involving inertial vibrations of a frictionally-controlled oscillator and the other a swarm of Low-Frequency Earthquakes—are discussed to explain these observations.
