No Need to Panic. No Tsunami, Even If it comes, wil be only 0.5 Meters High..
Earthquake overview : A very strong but probably harmless earthquake/aftershock occurred approx. 60 km out of the Japanese Eastern Honshu coast. JMA
Japan had a tsunami advisory in place for 37 minutes.
the tsunami advisory has been lifted for this earthquake
Screenshot from the JMA intensity map (courtesy JMA Japan) - the orange color is the 5- intensity zone
07:00 UTC : TEPCO, the owner of the Fukushima Nuclear plant has reported that NO additional damage was inflicted to his facilities.
06:46 UTC : JMA has released the sequence of events as reported by their services :
15:15 JST 19 Aug 2011 Fukushima-ken Oki M6.8 Cancel of Tsunami Warnings/Advisories
14:39 JST 19 Aug 2011 Fukushima-ken Oki M6.8 High Tide Time and Estimated Tsunami Arrival Time at each place
14:39 JST 19 Aug 2011 Fukushima-ken Oki M6.8 Estimated Tsunami arrival time and Height
14:38 JST 19 Aug 2011 Fukushima-ken Oki M6.8 Tsunami Advisories
Based on their report, the tsunami advisory has lasted 37 minutes. One of the JMA concerns was also the high tide which increases the tsunami danger
06:42 UTC : Those among you who want to see a very detailed tsunami map from this earthquake should click on this link. The map loads slowly, but
gives a very good impression of the vularable areas on the the eastern Honshu coast (at least for this earthquake)
06:30 UTC : I Have Felt It reports
Chiba : light shaking indicated (MMI IV)
06:30 UTC : the tsunami advisory has been lifted for this earthquake (tsunami advisory was lifted at 06:15 UTC). The tsunami advisory was called for
the following prefectures : Miyagi and Fukushima
06:24 UTC : People who are concerned with the nuclear power plants in the area (as they were again hit bu this earthquake), should be told that the
risk for the nuclear plants comes from high wave tsunamis only. A 0.5 meter tsunami is not a real treat for the plants + the shaking should be at
least 5+ or 6 JMA to be problematic.
06:23 UTC : 5- intensity has been reported for the following areas : Miyagi Misato-machi Kimatsuka*, Zao-machi Enda*, Ishinomaki-shi Monoucho*
06:21 UTC : GDACS has not released a tsunami report which is a good sign as they are very specialized in tsunami prediction (GDACS is mostly
calculating the theoretical values based on the USGS data)
06:14 UTC : NOAA reports that :
…A STRONG EARTHQUAKE HAS OCCURRED BUT A TSUNAMI IS NOT
EXPECTED ALONG THE CALIFORNIA/ OREGON/ WASHINGTON/
BRITISH COLUMBIA OR ALASKA COASTS…
06:12 UTC : Japan JMA seismological agency is reporting a magnitude of 6.8 at a depth of 20 km.
06:10 UTC : The expected tsunami arrival times are :
MIYAGI PREF. (*1)
Ishinomaki-shi Ayukawa 15:00 JST 19 Aug
Sendai-ko 5:30 JST 19 Aug
FUKUSHIMA PREF. 14:50 JST 19 Aug
Iwaki-shi Onahama 15:20 JST 19 Aug
Soma 15:20 JST 19 Aug
06:09 UTC : WAPMERR, the theoretical Earthquake Loss Estimate engine confirms our own opinion that there will be no injured or deaths based on this
06:09 UTC :2,832,000 people will have felt a moderate shaking, 6,0067,000 will experience a light shaking and nearly 40 million people a weak
06:07 UTC : The earthquake will certainly be well felt in Tokyo
06:07 UTC : Although a tsunami advisory is in place, the shaking of this earthquake will be strong but probably not damaging as the epicenter is at 60
km from the coast.
06:04 UTC : The earthquake region (strongest felt is) : FUKUSHIMA-KEN OKI
06:02 UTC : A Tsunami advisory in in place for the IWAKI coast : The max. expected wave height is 0.5 meter
06:01 UTC : Although this is an extremely strong earthquake, the JMA intensity data is revealing (only) a -5 result, which means probably NOT
