Multi-planar structures in the aftershock distribution of the Mid Niigata prefecture Earthquake in 2004
A shallow destructive inland earthquake of M6.8 occurred on Oct. 23, 2004 (JST) in the middle part of Niigata prefecture, Japan. The aftershock activity was high as compared to those of the other shallow inland earthquakes in Japan. We relocated the sources of the main shock and aftershock activity by adopting the double-difference earthquake location algorithm. The precisely relocated hypocent...
متن کاملQuantifying early aftershock activity of the 2004 mid-Niigata Prefecture earthquake (Mw6.6)
[1] We analyze the early aftershock activity of the 2004 mid-Niigata earthquake, using both earthquake catalog data and continuous waveform recordings. The frequencymagnitude distribution analysis of the Japan Meteorological Agency (JMA) catalog shows that the magnitude of completeness of the aftershocks changes from values around 5.0, immediately after the main shock, to about 1.8, 12 hours la...
متن کاملEffect of the 2004 Mid Niigata Prefecture earthquake on glycemic control in type 1 diabetic patients.
At 5:56 p.m. on October 23, 2004, a major earthquake of magnitude 6.8 on the Richter scale struck the Chuetsu district of Niigata Prefecture, Japan, a rural area with mountain villages. Strong aftershocks of grade 5-6 on the Japanese Intensity Scale continued for 2 months. We investigated changes in the HbA1c levels of 65 type 1 diabetic patients with insulin therapy before and throughout the 1...
متن کاملEffect of the 2004 mid niigata prefecture earthquake on patients with endocrine disorders.
A major earthquake (Richter scale magnitude 6.8) struck the Chuetsu district of Niigata Prefecture, Japan, a rural area with mountain villages, on October 23, 2004. Strong aftershocks (Grade 5-6 on the Japanese intensity scale, JIS) continued for 2 months. We analyzed the earthquake's impact on 229 patients with various endocrine disorders [6 central diabetes insipidus (CDI), 16 adrenal insuffi...
متن کاملObservation of Earth's free oscillation by dense GPS array: After the 2011 Tohoku megathrust earthquake
Day-scale Earth's free oscillation after large earthquakes has been detected by underground instruments such as strainmeters, gravimeters and seismometers, to investigate Earth's internal structure, geodynamics, and source properties of earthquakes. Here we show that Global Positioning System (GPS) can also detect the signals of the Earth's free oscillation. A dense GPS array in Japan (GEONET) ...
