(CNA, Tokyo, 18th, Comprehensive Foreign Report) A series of earthquakes occurred earlier today in Nagano Prefecture, Japan, with a maximum seismic intensity of 5 Upper observed in Omachi City. The Japan Meteorological Agency (JMA) pointed out that "there is an active fault zone near the epicenter. If a major earthquake occurs, tremors of intensity 6 Upper or higher could appear," urging the public to stay alert.
According to reports from Japan's TBS and NHK, an earthquake with an estimated magnitude of 5.0 occurred in northern Nagano Prefecture at around 1:20 PM today (12:20 PM Taipei time), with Omachi City observing a maximum intensity of 5 Upper. Surrounding areas also felt tremors ranging from intensity 1 to 3.
After a detailed analysis of observation data, the JMA updated the depth of this earthquake from 10 kilometers to 8 kilometers.
About an hour and a half later, at around 2:54 PM (1:54 PM Taipei time), another earthquake struck northern Nagano, with Nagano City and Omachi City recording a maximum intensity of 5 Lower. According to JMA observations, the estimated magnitude was 5.1 with a depth of about 10 kilometers.
At around 5:47 PM (4:47 PM Taipei time), yet another earthquake occurred in northern Nagano, with an estimated magnitude of 3.0 and a depth of about 10 kilometers. A maximum intensity of 3 was felt in Omachi City.
Fortunately, none of these earthquakes posed a tsunami threat.
The JMA held a press conference stating, "For about the next week, especially the next 2 to 3 days, we hope the public stays alert for earthquakes with a maximum intensity around 5 Upper," further noting that "earthquakes accompanied by even more severe shaking could also occur."
The JMA also stated, "In areas with strong shaking, the risk of rockfalls and landslides will increase," urging the public to pay close attention to subsequent seismic activities and rainfall conditions.
The JMA pointed out, "There are fault zones near the epicenters of these earthquakes, and this area has experienced consecutive earthquakes with strong shaking in the past."
JMA officials said, "We cannot rule out that surrounding active faults could trigger a major earthquake. If it happens, we expect shaking of intensity 6 Upper or higher."
