【巴西傳媒報導:美國加州將可能發生7.0級以上地震】
以下是一封於2016年9月26日寄出的信件
朱馬後炮果然就是天下文章一大抄。然後再把寄出信件的日期往前修改,弄得好像是真的他夢到的一樣。
從底下這些文章及關鍵字,包含機率、日期、震央深度、規模、地點等,就可發現他還真的厚臉皮完全照抄,果真是global search 世界新聞/網站,來發自己的白日夢

https://www.facebook.com/USGeologicalSur...?type=3&theaterEarthquake Swarm Activity Near Bombay Beach
An earthquake swarm near Bombay Beach, California, started on 2016 Sept. 26 at 4:03 am (PDT) in the Brawley Seismic Zone, which lies near the southern terminus of the San Andreas Fault.
The swarm includes 142 events so far (as of 26 Sep 2016, 11:31PM PDT) in the magnitude range M1.4 to M4.3. Relocations of these events show that they are occurring in the depth range 4 to 9 km.
The earthquakes are occurring near a set of north-northeast trending cross-faults in the Salton Sea. The cross-faults are part of a fault network that connect the southernmost end of the San Andreas fault with the Imperial fault. Some of the cross-faults are oriented such that they add stress to the San Andreas fault and the San Jacinto fault system when they rupture in small earthquakes like those in the ongoing swarm.
Earthquake Swarms & Probabilities
Swarm-like activity in this region has occurred in the past, so this week’s activity, in and of itself, is not necessarily cause for alarm.
Preliminary calculations indicate that, as of 10:00 am (PDT) Sept. 27, 2016, there is a 0.03%-1% chance (1 in 3000 to 1 in 100) of a magnitude 7 or greater earthquake being triggered on the Southern San Andreas fault within the next next seven days through October 4, with the likelihood decreasing over time. This probability range is estimated using several models developed in California to assess foreshock/aftershock probabilities.

一周震200次!美專家:恐喚醒百年加州大斷層
自上周一開始,南加州薩爾頓海(Salton Sea)持續發生不下200次小型地震。雖然強度只有4級,不過,因為這些地震發生於聖安德烈亞斯斷層末端以南地區,是加州最複雜地震帶之一。科學家擔心,有一天會喚醒一直沉睡的聖安德烈亞斯斷層,發生大地震。
「洛杉磯時報」(LA Times)引述美國地質調查所(US Geological Survey)說,頻密的群震約有3次超過規模4,其中兩次發生在26日晚間,超過規模3共有9次。報導說,多數的地震集中在薩爾頓海(Salton Sea)畔的孟買海灘(Bombay Beach),環繞薩爾頓海的區域也能感受到搖晃。這個地區常見類似小規模晃動的群震,2009年薩爾頓海也曾發生超過200次小規模群震的紀錄。
報導指出,由於北美與太平洋板塊相互擠壓,薩爾頓海位於地殼非常薄的頂端,以致不斷被拉扯,加上這個地區分布許多斷層帶,包括著名的聖安德里亞斯斷層(San Andreas Fault),以致地牛常翻身。科學家分析,群震次數頻繁主因是地層薄弱,溫度比較高的物質可能太靠近表層,導致有感震動。
聖安德烈亞斯斷層在加州最長,也是該州其中一個最危險的斷層。南加州地震中心主心喬丹說,該斷層自1857年起一直「太靜了」。自從1932年安裝地震傳感器以來,加州總共3次發生持續不斷的群震。最新的群震次數多過2001年和2009年,增強了專家對大地震即將發生的疑心。
至於這是否象徵將發生大地震的前兆,地震學家瓊斯(Lucy Jones)說,超過規模4的地震發生在聖安德里亞斯斷層附近,稍稍增加了大地震發生的機率,但這些群震沒有伴隨大規模的震度,很有可能什麼都不會發生。美國地質調查局在2008年警告說,7.8級的大地震可能釀成1800人死亡、5萬人受傷,並造成2000億美元的損失。
加州因位於環太平洋地震帶內,屬於好發地震。1994年1月17日洛杉磯大地震,造成62人死亡、9000多人受傷、2萬5000人無家可歸,財產損失超過300億美元。去年太空總署噴射推進實驗室(JPL)地震學家預測,南加州未來兩年半內,發生規模5以上地震的可能性高達99.9%。

【新聞】Earthquake advisory for parts of Southern Califonia,
Increased probability of moderate earthquake
http://www.keyt.com/.../earthquake-advisory-for.../100711323The California Office of Emergency Services has issued an earthquake advisory for Southern California. Alerting several counties that the probability of a major earthquake is more likely this week.
The earthquake advisory is in effect for the following counties: Ventura, San Diego, San Bernardino, Riverside, Orange, Los Angeles, Kern and Imperial.
The advisory was issued following a series of small magnitude earthquakes near Bombay Beach, Salton Sea.
The California Earthquake Prediction Evaluation Council believes that stresses associated with this earthquake swarm may increase the probability of a major earthquake on the San Andreas fault by up to 1% until October 4.
“The scientist rated that there was an increased probability of up to 1% so a slight increase. Really at the end of the day it is a great reminder to us that we live in earthquake country and that earthquakes can strike, suddenly, violently and with no warning so everyones best bet is to be prepared prior to,” said Kevin McGowan with the Ventura County Office of Emergency Services.
While the Operation of Emergency Services prepares there are also a few things you can do as well.
“Drop, cover, and hold when an earthquake occurs. Prior to, have a disaster kit. Definitely an important thing 3-days at a minimum worth of water and food, extra clothing is important. If you have prescription medicine, definitely have prescription medicine on hand,” said McGowan.
After the earthquake stops shaking, there is one more thing you need to remember if you live along the coast.
“If it was a significant earthquake you should take action yourself and immediately leave the tsunami inundation zone by leaving, and heading inland or to high ground,” said McGowan.
