Can anybody guess or explain how and why such things happen?

i have received both mail from USGS EXACTLY 1 hR AND 01 MINUTES APART

QUESTIONS ARE 
1)HOW AND WHY SUCH ERRORS OCCUR?
2)WHY DOES IT TAKES ONE HOUR TO RECOGNIZE THE ERROR?
3)FIRST THINK,HOW SUCH A BIG QUAKE OF 5.5+ CAN BE MISJUDGED?
4) IT IT IS A COMPUTER OR SOFTWARE ERROR ,HOW WE CAN TRUST SUCH SOFTWARE?
5)LAST BUT NOT LEAST
HOW CAN SEISMOLOGISTS IN GENERAL AND USGS IN PARTICULAR DEMANDS FROM
THOSE(LIKE ME )WORKING IN THE FIELD OF PREDICTION TO PREDICT EXACT MAGNITUDE(+ OR -0.3),THAT TOO BEFORE IT HAS OCCURRED?

I WOULD LIKE USGS AND /OR SEISMOLOGIST TO ANSWER THESE QUESTIONS
