Title Alternative Onset time and location of the main rupture of the 2018 Hokkaido Eastern Iburi, Japan, earthquake
FullText URL esr_029_049_063.pdf
Author KOWARI, Hirofumi| KOMATSU, Masanao| TAKENAKA, Hiroshi|
Abstract The rupture process at the beginning stage of the 2018 Hokkaido Eastern Iburi, Japan, earthquake (MJ 6.7) is investigated by analyzing P-wave records from local strong-motion stations. The records show about 3 s of small amplitude arrival (so-called "initial rupture phase") followed by the onset of the main energy release ("main rupture phase"). In this paper we address the issue: where the seismic energy release corresponding to the main rupture phase started at the primary stage of the main rupture, by locating the main rupture onset position. For this aim we applied the 2D and the 3D search methods to estimate the relative location of the onset of the main rupture with respect to the hypocenter, and the time difference between them. The 2D method assumes a plausible initial fault plane and locates the main rupture onset position on the initial fault plane, while the 3D method does not require such assumed fault planes. In the 2D method we employed each of the nodal planes of the first-motion focal mechanism as the initial rupture plane. The 3D method was able to give a better solution than the 2D one. It suggests that the main rupture initiation point might not be on the same fault plane as the hypocenter is. The solution shows that the main rupture onset point is 5.8 km southward and 2.5 km upward from the hypocenter, with the rupture time of 3.3 s from the origin time. It is consistent with the previous studies on the relationship between the magnitude and the initial rupture duration.

Prolonged Double-Low Time and the Incidence of Postoperative Delirium in Surgical ICU Patients

Author Yamanoi, Tomoko| Suzuki, Satoshi| Kaku, Ryuji| Morimatsu, Hiroshi|
Abstract An intraoperative double-low condition is defined as concurrent low values for bispectral index (BIS) and mean arterial pressure (MAP), and may predict perioperative outcomes. We hypothesized that prolonged double-low times might be associated with an increased incidence of postoperative delirium. We conducted a single-center retrospective observational study on patients who had been admitted to our hospital’s intensive care unit (ICU) after surgery and whose BIS and MAP data had been recorded during general anesthesia. The primary outcome was the incidence of postoperative delirium. A double-low condition was defined as BIS < 45 and MAP <75 mmHg. The total double-low time was calculated in 1-min increments and used to divide the patients into quintiles. Multiple logistic regression analyses were conducted. Among the 334 patients included in the study, the incidence of postoperative delirium was 15.6% (n=52). Multiple logistic regression analysis revealed that a prolonged double-low time, defined as a total double-low time of > 42 min (i.e., third, fourth, and fifth quintiles), was significantly associated with an increased incidence of postoperative delirium (adjusted odds ratio: 2.61, 95% confidence interval: 1.27-5.37, p=0.009). Prolonged double-low time during general anesthesia was independently associated with an increased incidence of postoperative delirium in surgical ICU patients.
