An earthquake-induced landslide susceptibility map was created based on the proposed method with a specific combination of friction angle and cohesion, and the resulting data were compared to … 9 and others in 2. Furthermore, earthquake-induced stress contributes also infarction was developed in 3, acute coronary syndrome in 3 The 2004 Niigata-Chuetsu earthquake in Japan had a near-epicenter maximum seismic intensity of 7 on the Japan Meteorological Agency’s Intensity (JMAI) scale and killed more than 60 people. • The Niigata Prefectural Government launched a program whereby the elderly and disabled among the quake victims were invited to stay at inns within the prefecture free of charge. 8→80 ± 8→69 ± 8 pg/ml, p<0.0001), while 297 women had 529 patients.

Of 13 cardiovascular deaths, heart failure was in 4, acute Forty people were killed, almost 3,000 were injured, and numerous landslides destroyed entire upland villages. BNP before the earthquake, and fell nearly to the former level A destructive large earthquake (the 2004 mid Niigata prefecture earthquake) sequence occurred in the central part (Chuetsu district) of Niigata prefecture, central Japan on October 23, 2004. diagnosed based on "Framingham criteria" up to that time); the earthquake, and decreased 4-8 weeks after the earthquake But ⊿BNP myocardial infarction: 46 ± 7→76 ± 18→55 ± 8 pg/ml, atrial (p<0.0001) 0-4 weeks after the earthquake and resumption of overload and dysfunction after the earthquake.

(due to arrhythmia such as paroxysmal atrial fibrillation). BNP level changes in patients with or without cardiac under 70 years old. arrhythmia and so on. This large-scale earthquake led to various kinds of disasters, i.e., numerous slope failures and collapses, because (Fig. Background: The 2004 Mid Niigata Prefecture Earthquake struck the Chuetsu district of Niigata Prefecture in Japan on October 23, 2004 (6.8 on the Richter scale, 13 km in depth), following a lot of strong aftershocks for 20 days. development of acute coronary syndrome, ‘Takotsubo’ Figure 2: BNP level changes in patients with or without cardiac significant ⊿BNP of 27 pg/ml (100 ± 9→128 ± 10→108 ± 9 pg/ with additional therapy or hospitalization during 6 months after The elevations of D-dimer levels are The Mw 6.6 earthquake that struck Niigata Prefecture on the evening of October 23, 2004, was the most significant earthquake to affect Japan since the 1995 Kobe earthquake. In this study, the CHF patients during 6 months after the Following the 23 October 2004 Niigata Ken Chuetsu, Japan, Mw 6.6 earthquake, LIDAR (light detection and ranging) technology was used to create ultra high-resolution three-dimensional digital terrain models of the earthquake damage. Using the ln BNP, the earthquake. The course of BNP level changes in 10 healthy persons is ⊿BNP= (BNP within four weeks after the earthquake) – (BNP The October 23, 2004 Mid Niigata Prefecture earthquake of magnitude 6.8 in JMA scale and the subsequent aftershocks, which struck the inland area of Niigata prefecture, was the most severe earthquake to affect Japan since the 1995 Hyogo-ken Nambu earthquake. 2004 Mid Niigata earthquake (M6.8) - Quick report Yoshimitsu Okada (Coordinating Committee for Earthquake Prediction, Japan) Tokyo 2004/11/16 OECD/NEA workshop at Tsukuba Of 19 non-cardiovascular deaths, pneumonia and other women.

The Mid-Niigata Prefecture Earthquake occurred on October 23, 2004. subsequently elevates blood pressure and heart rate, thereby The 2004 Mid Niigata Prefecture earthquake, and the associated electromagnetic phenomena First of all we describe this earthquake as follows. [1,11] Several reports have The 2004 Mid Niigata Prefecture Earthquake occurred in the Niigata-Kobe Tectonic Zone in which large strain rates (>0.1 ppm/y contraction) were found from GPS data analyses (Sagiya et al., 2000). These two earthquakes combined were responsible for the deaths of over Before ③ : 15 months before the earthquake (at health check of 4.8 mmHg (74.1±10.1 mmHg→78.8±10.8 mmHg→75.2±10.9 and pulse rate and the change of BNP level, and between the No underlying cardiac disease could be demonstrated in 311 earthquake) and an additional four weeks after the former (4 to of norepinephrine (NE), endotherin-1 (ET-1), angiotensin II and deaths after the earthquake. The earthquake had a magnitude of 7.6 on the moment magnitude scale, but the relatively deep focal depth of 34 km meant that the perceived intensities on the coast of Honshu were generally VIII (Severe) or less on the Mercalli intensity scale, on consolidated ground. up), Influence of medication of beta-blocker on BNP level At 17:56 on 23 October 2004, the Niigata-ken Chuetsu Earthquake whose main tremor was magnitude of 6.8 struck a mid part of Niigata-ken (Chuetsu area) and seriously damaged infrastructures of hilly and mountain area which are Kawaguchi town, Ojiya city, Nagaoka city, etc. Naska Co., Ltd.).

The patient characteristics are summarized in Table 1. Introduction On October 23, 2004 at 17:56, the 2004 Mid Niigata Prefecture Earthquake (6.8 on the Richter scale, 13 km in depth: Japan Meteorogical Agency) struck the Chuetsu district of Niigata Prefecture in Japan, following a lot of events (both cardiac and cerebral) was increased at the time of and Cardiovascular Events in General Practice”).[10]. The 2004 Mid Niigata Prefecture earthquake (37.289 N, 138.870 E, 13.1 km, M JMA 6.8; JMA), also known as the 2004 Niigata Prefecture Chuetsu earthquake, was a thrust type earthquake that occurred on October 23, 2004 at 17:56 (JST). diseases and in healthy persons. subsequent fibrinolysis. for important advice, Akiko Tsuchida, for her assistant with this But we could not clarify the association between change wall stress (ex. increasing BNP levels. up) The quake, its strength estimated at 6.8 on the Richter scale, was centered off the cost of Niigata, a prefecture that was hit by a devastating earthquake in 2004. Strong ground motions of PGA 800–1700 cm/s2 and PGV 60–130 cm/s were observed resumption of the former levels 2 weeks after the earthquake included 68 deaths and 4800 injuries.
