Maps of Japan’s earthquake

[Please see links to various other resources in the comments section below]

Lots of amazing data out there about the earthquake in Japan and loads of beautiful maps!

Here are some:

Above is an “energy map” provided by the US National Oceanic and Atmospheric Administration (NOAA), which shows the intensity of the tsunami caused by the earthquake which struck Japan.

Another:

Source: NOAA Center for Tsunami Research, Pacific Marine Environmental Laboratory.

Note how close Indonesia is to Japan, especially compared to the U.S.  The Pacific east of Japan is enormous!

Below is the live USGS map showing Japan, with recent earthquakes in red. The larger the square, the stronger the earthquake.

 

Post links to more if you come across any.

    The actual warning issued. Relevant agencies use this to active response and evacuation plans

    WEPA40 PHEB 111938
    TSUPAC

    TSUNAMI BULLETIN NUMBER 016
    PACIFIC TSUNAMI WARNING CENTER/NOAA/NWS
    ISSUED AT 1938Z 11 MAR 2011

    THIS BULLETIN APPLIES TO AREAS WITHIN AND BORDERING THE PACIFIC
    OCEAN AND ADJACENT SEAS…EXCEPT ALASKA…BRITISH COLUMBIA…
    WASHINGTON…OREGON AND CALIFORNIA.

    … A WIDESPREAD TSUNAMI WARNING IS IN EFFECT …

    A TSUNAMI WARNING IS IN EFFECT FOR

    JAPAN / RUSSIA / INDONESIA / PAPUA NEW GUINEA /
    VANUATU / NIUE / TONGA / MEXICO /
    FR. POLYNESIA / PITCAIRN /GUATEMALA / EL SALVADOR /
    COSTA RICA / NICARAGUA / ANTARCTICA /
    PANAMA / HONDURAS / CHILE / ECUADOR / COLOMBIA / PERU

    THIS BULLETIN IS ISSUED AS ADVICE TO GOVERNMENT AGENCIES. ONLY
    NATIONAL AND LOCAL GOVERNMENT AGENCIES HAVE THE AUTHORITY TO MAKE
    DECISIONS REGARDING THE OFFICIAL STATE OF ALERT IN THEIR AREA AND
    ANY ACTIONS TO BE TAKEN IN RESPONSE.

    AN EARTHQUAKE HAS OCCURRED WITH THESE PRELIMINARY PARAMETERS

    ORIGIN TIME – 0546Z 11 MAR 2011
    COORDINATES – 38.3 NORTH 142.4 EAST
    DEPTH – 24 KM
    LOCATION – NEAR EAST COAST OF HONSHU JAPAN
    MAGNITUDE – 8.9

    LAT – LATITUDE (N-NORTH, S-SOUTH)
    LON – LONGITUDE (E-EAST, W-WEST)
    TIME – TIME OF THE MEASUREMENT (Z IS UTC IS GREENWICH TIME)
    AMPL – TSUNAMI AMPLITUDE MEASURED RELATIVE TO NORMAL SEA LEVEL.
    IT IS …NOT… CREST-TO-TROUGH WAVE HEIGHT.
    VALUES ARE GIVEN IN BOTH METERS(M) AND FEET(FT).
    PER – PERIOD OF TIME IN MINUTES(MIN) FROM ONE WAVE TO THE NEXT.

    NOTE – DART MEASUREMENTS ARE FROM THE DEEP OCEAN AND THEY
    ARE GENERALLY MUCH SMALLER THAN WOULD BE COASTAL
    MEASUREMENTS AT SIMILAR LOCATIONS.

    EVALUATION

    SEA LEVEL READINGS CONFIRM THAT A TSUNAMI HAS BEEN GENERATED
    WHICH COULD CAUSE WIDESPREAD DAMAGE. AUTHORITIES SHOULD TAKE
    APPROPRIATE ACTION IN RESPONSE TO THIS THREAT. THIS CENTER WILL
    CONTINUE TO MONITOR SEA LEVEL DATA TO DETERMINE THE EXTENT AND
    SEVERITY OF THE THREAT.

    A TSUNAMI IS A SERIES OF WAVES AND THE FIRST WAVE MAY NOT BE THE
    LARGEST. TSUNAMI WAVE HEIGHTS CANNOT BE PREDICTED AND CAN VARY
    SIGNIFICANTLY ALONG A COAST DUE TO LOCAL EFFECTS. THE TIME FROM
    ONE TSUNAMI WAVE TO THE NEXT CAN BE FIVE MINUTES TO AN HOUR, AND
    THE THREAT CAN CONTINUE FOR MANY HOURS AS MULTIPLE WAVES ARRIVE.

    FOR ALL AREAS – WHEN NO MAJOR WAVES ARE OBSERVED FOR TWO HOURS
    AFTER THE ESTIMATED TIME OF ARRIVAL OR DAMAGING WAVES HAVE NOT
    OCCURRED FOR AT LEAST TWO HOURS THEN LOCAL AUTHORITIES CAN ASSUME
    THE THREAT IS PASSED. DANGER TO BOATS AND COASTAL STRUCTURES CAN
    CONTINUE FOR SEVERAL HOURS DUE TO RAPID CURRENTS. AS LOCAL
    CONDITIONS CAN CAUSE A WIDE VARIATION IN TSUNAMI WAVE ACTION THE
    ALL CLEAR DETERMINATION MUST BE MADE BY LOCAL AUTHORITIES.

    BULLETINS WILL BE ISSUED HOURLY OR SOONER IF CONDITIONS WARRANT.
    THE TSUNAMI WARNING WILL REMAIN IN EFFECT UNTIL FURTHER NOTICE.

    THE JAPAN METEOROLOGICAL AGENCY MAY ALSO ISSUE TSUNAMI MESSAGES
    FOR THIS EVENT TO COUNTRIES IN THE NORTHWEST PACIFIC AND SOUTH
    CHINA SEA REGION. IN CASE OF CONFLICTING INFORMATION… THE
    MORE CONSERVATIVE INFORMATION SHOULD BE USED FOR SAFETY.

    THE WEST COAST/ALASKA TSUNAMI WARNING CENTER WILL ISSUE PRODUCTS
    FOR ALASKA…BRITISH COLUMBIA…WASHINGTON…OREGON…CALIFORNIA.
