GPS监测点,the Nicoya Peninsula

受惊了!抱歉我不是地震专业的,而且没去中南美工作过,所以不太清楚你那里的地质条件。但我知道有专门机构负责。我相信你那里的火山地震监测和灾害预警要比国内要好得多。看孩子在学校也有演习。

这段时间要经常听新闻了解情况。

这里有信息链接,有时间可以看看:

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

其中的重要预测:
"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.

the Nicoya gap 离你家多远?the Nicoya Peninsula, northwestern Costa Rica

预警系统:
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.

建议你们自己或通过老公工作的公司了解必要的信息和安全防范。

比如:

火山的活动性监测和预报发布(及时性)

火山与你家距离(估计风险)

你家附近是否有活动性断层(active fault)?

有的话什么类型?多远?(房屋破坏风险)

万一地震,你家附近是否有山体滑坡或崩塌的可能性?(房屋和人身安全)

你家与海滩距离?(海浪破坏风险)

房屋抗震能力?(人身安全)

主导风向 (避开毒气)

应急避难地点和撤离路线(安全、高效)

有没有社区行动和政府组织的应急措施?

还有,防止地震造成的火灾 (电、煤气、天然气?)

万一发生停水、停电、生病、外伤的应急

即食高能食物(压缩饼干、巧克力等)

想想还有什么?

看看邻居有什么好经验?

总之,预防为主。有准备就行。

我帮你盯着一点。
