GPS監測點,the Nicoya Peninsula

受驚了!抱歉我不是地震專業的,而且沒去中南美工作過,所以不太清楚你那裏的地質條件。但我知道有專門機構負責。我相信你那裏的火山地震監測和災害預警要比國內要好得多。看孩子在學校也有演習。

這段時間要經常聽新聞了解情況。

這裏有信息鏈接,有時間可以看看:

Costa Rica Earthquake Informationhttp://earthquake.usgs.gov/regional/world/?regionID=39

Observatorio Vulcanológico y Sismológico de Costa Rica:http://www.ovsicori.una.ac.cr/

Earthquakes and Geology in Costa Rica:http://www.costarica-homeschool.com/cw/earth.html

其中的重要預測:
"the Nicoya gap has the potential to generate an earthquake with moment magnitude above 7.5".

The “Nicoya seismic gap” is bounded by the rupture areas of two large earthquakes that occurred at both sides of this peninsula; MW 7.0 in 1990 to the southeast and the 1992 MW 7.6 off Nicaragua to the northwest. A strong coupling of the two plates is manifested in this seismic gap by low background seismicity, the sharp edge to the aftershock zone of the 1990 and 1992 earthquakes , and the northeastward movement of the Nicoya peninsula recorded with GPS observations. Protti et al. estimated that a MW=7.5 earthquake is likely to occur in the Nicoya seismic gap.

預警係統:
An Early Warning System:radio transmissions can give San Jose about 30 seconds of warning before the earthquake waves demolish the city.

On the Nicoya Peninsula, however, there will be no prior warning.

建議你們自己或通過老公工作的公司了解必要的信息和安全防範。

比如:

火山的活動性監測和預報發布(及時性)

火山與你家距離(估計風險)

你家附近是否有活動性斷層(active fault)?

有的話什麽類型?多遠?(房屋破壞風險)

萬一地震,你家附近是否有山體滑坡或崩塌的可能性?(房屋和人身安全)

你家與海灘距離?(海浪破壞風險)

房屋抗震能力?(人身安全)

主導風向 (避開毒氣)

應急避難地點和撤離路線(安全、高效)

有沒有社區行動和政府組織的應急措施?

還有,防止地震造成的火災 (電、煤氣、天然氣?)

萬一發生停水、停電、生病、外傷的應急

即食高能食物(壓縮餅幹、巧克力等)

想想還有什麽?

看看鄰居有什麽好經驗?

總之,預防為主。有準備就行。

我幫你盯著一點。
