title = "Microseismicity and faulting in the southwestern Okinawa Trough",
abstract = "In November 2003, 15 ocean bottom seismometers were deployed in the southwestern Okinawa Trough. More than 3300 microearthquakes were located during the 10-days passive seismic experiment. The earthquake activity is characterized by the ceaseless occurrence of small earthquakes in the vicinity of all the instruments. The seismicity is essentially restricted to the central part of the Southwestern Okinawa Trough, except for one cluster of events situated in the southern part of it (cluster 2). The seismic activity terminates abruptly against the NE-SW trending prolongation of the Lishan fault. Most of the microearthquakes are aligned along the E-W trending normal faults, showing where the present-day active normal faulting occurs and how it accounts for the N-S extension in the Okinawa Trough. According to the P-wave velocity spectra estimated from some deep earthquakes located beneath the cross backarc volcanic trail area, the existence of a lower crustal/upper mantle magma chamber is confirmed by the presence of low frequency earthquakes in the 3-10 Hz bandwidth.",

note = "Funding Information: We thank the captain and crew of the R/V Ocean Research I for their help during the cruise and the Central Weather Bureau (CWB) of Taiwan for providing the land station data. We thank Wen-Nan Wu and Julie Perrot for their help in using the seismic processing program. The GMT software package was used to draw some of the figures ( Wessel and Smith, 1991 ). This work is part of an ongoing cooperative project between France and Taiwan encouraged and supported by the Institut Fran{\c c}ais de Taipei (IFT) and by the National Science Council (NSC), Taiwan. Pertinent discussions with Yvonne Font, Nicole Bethoux, Ban Kuo, and Ruey-Juin Rau are acknowledged.",
