Recently, a strong outbreak occurred on the Noto Peninsula in Ishikawa Prefecture, Japan, resulting in serious loss of life and property. So far, 128 people have been killed and 222 people are missing. This timeIt is Kumamoto since 2016since,Japan**For the first time, the death toll exceeded 100. At the same time, the economic losses are also very large, with preliminary estimates of direct economic losses exceeding 800 billion yen.
Why this timeWhat about such heavy losses?ExceptIn addition to factors such as the huge energy, shallow epicenter, and strong vibration, there are other reasons that led to this timeof serious destructive power.
First, road disruptions led to delays in rescue efforts. In the aftermath of the incident, there was a widespread disruption of roads in the affected area. SomeHighwaysEven the national highways in Ishikawa Prefecture are impassable. The runway at Noto Airport was also closed due to cracks. This makes it impossible for relief materials and machinery to reach the disaster area, making relief efforts more difficult.
Secondly, the local housesEarthquake resistantInsufficient performance. According to reports, some of the houses in the hardest-hit areas do not conform to the Japanese stateEarthquake resistantstandard, only half meet the requirements. This means that these houses are inIt cannot withstand too much vibration and is easy to collapse or be damaged. Moreover, the aging of the Noto Peninsula is also exacerbating the destructive force. For example, in Zhuzhou City, the elderly over 65 years old account for 51 of the total population7%, which makes itwithSecondary disastersThe harm to the elderly is even more severe.
In addition, it is worth mentioning that this timeIt is a swarm type, without significant mainshocks. Through multiple sub-levelsThe main energy is gradually released, which leads to:Expansion of scale. The epicenter area stretches from the Noto Peninsula to the vicinity of Sado Island in Niigata Prefecture and may be up to 150 kilometers long. Such a wide range of fault rupture makesThe scale has become enormous.
Anyway, this timeThe reason for the heavy loss of people and property is because:The scale of itself is huge, and the disruption of roads delays rescue efforts to local housesEarthquake resistantInsufficient performance and aging problems are caused by a combination of factors.
In the face of such a natural disaster, the importance of rescue work cannot be overstated. Local** and relevant agencies should strengthen the housingEarthquake resistantPerformance review and evaluation to ensure the safety of the building. At the same time, it is necessary to strengthen publicity and education before the disaster to raise the residents' awareness of disaster prevention, and to strengthen planning and management of post-disaster reconstruction work to ensure that the lives of the victims can be restored smoothly.
In short,is a devastating natural disaster, although we cannot ** or prevent itbut we can reduce the damage by stepping up preventive measures and emergency relief efforts. Only a scientific and rational responsein order to better protect the safety of people's lives and property.
