Tsunami Warning Issued After Large Quake Strikes Off Northeastern Japan's Coast


DEVELOPING: TOKYO -- Japan was rattled by a strong aftershock and tsunami warning Thursday night nearly a month after a devastating earthquake and tsunami flattened the northeastern coast.
Announcers on Japan's public broadcaster NHK told coastal residents to run to higher ground and away from the shore.
The Japan meteorological agency issued a tsunami warning for a wave of up to 6 feet after the magnitude-7.1 aftershock. The warning was issued for a coastal area already torn apart by last month's tsunami, which is believed to have killed some 25,000 people and has sparked an ongoing crisis at a nuclear power plant.
Officials at the tsunami-ravaged Fukushima Dai-ichi nuclear plant said there's no immediate sign of new problems caused by the aftershock. Plant operator Tokyo Electric Power Co. said it evacuated two workers there and seven at a sister plant to the south that was not badly damaged.
Officials say Thursday's aftershock hit 16 miles under the water and off the coast of Miyagi prefecture. The quake that preceded last month's tsunami was a 9.0-magnitude.

Buildings as far away as Tokyo shook for about a minute.
In Ichinoseki, inland from Japan's eastern coast, buildings shook violently, knocking items from shelves and toppling furniture, but there was no heavy damage to the buildings themselves. Immediately after the quake, all power was cut. The city went dark, but cars drove around normally and people assembled in the streets despite the late hour.
Paul Caruso, a geophysicist at the U.S. Geological Survey in Golden, Colo., said Thursday's quake struck at about the same location and depth as the March 11 quake. It's the strongest of the more than 1,000 aftershocks that have been felt since, except for a 7.9 aftershock that day.
The USGS said the aftershock struck off the eastern coast 40 miles from Sendai and 70 miles from Fukushima. It was about 205 miles from Tokyo.
A Pacific Tsunami Warning Center evaluation of the quake said an oceanwide tsunami was not expected. However, it noted quakes of that strength can cause waves that are destructive locally.

Japan Nuke Plant Operator to Dump Radioactive Water Into Ocean


The operator of Japan's stricken Fukushima nuclear plant said Monday it planned to dump thousands of tons of radioactive water into the Pacific, as the government was accused of covering up the extent of radiation levels.
"We have no choice but to release water tainted with radioactive materials into the ocean as a safety measure," Yukio Edano, the government’s chief spokesman told a new conference.
The Jiji press agency reported that a TEPCO spokesman said the 11,500 tons of water were only weakly radioactive and that the release would take place "as soon as necessary preparations are made."
The broadcaster NHK reported Monday that the Japanese government withheld the release of data showing that radiation exceeded safe levels more than 18 miles from the plant, beyond the 12-mile evacuation zone.
Computer projections taken March 16 showed that people from as far away as 18 miles from the nuclear plant would be exposed to more than 100 millisieverts of radiation if they were outdoors for 24 hours between March 12 and 24.

Japan Earthquake: Before and After











Rolling Stones - As Tears Go By - Live '06 Tokyo


Aerial photos taken over Japan have revealed the scale of devastation across dozens of suburbs and tens of thousands of homes and businesses.


Japan earthquake: before and after


The magnitude 9.0 Tohoku earthquake on March 11, 2011, which occurred near the northeast coast of Honshu, Japan, resulted from thrust faulting on or near the subduction zone plate boundary between the Pacific and North America plates. At the latitude of this earthquake, the Pacific plate moves approximately westwards with respect to the North America plate at a rate of 83 mm/yr, and begins its westward descent beneath Japan at the Japan Trench. Note that some authors divide this region into several microplates that together define the relative motions between the larger Pacific, North America and Eurasia plates; these include the Okhotsk and Amur microplates that are respectively part of North America and Eurasia.


The March 11 earthquake was preceded by a series of large foreshocks over the previous two days, beginning on March 9th with a M 7.2 event approximately 40 km from the epicenter of the March 11 earthquake, and continuing with another three earthquakes greater than M 6 on the same day.


Japan earthquake: before and after


The Japan Trench subduction zone has hosted nine events of magnitude 7 or greater since 1973. The largest of these, a M 7.8 earthquake approximately 260 km to the north of the March 11 epicenter, caused 3 fatalities and almost 700 injuries in December 1994. In June of 1978, a M 7.7 earthquake 35 km to the southwest of the March 11 epicenter caused 22 fatalities and over 400 injuries. Large offshore earthquakes have occurred in the same subduction zone in 1611, 1896 and 1933 that each produced devastating tsunami waves on the Sanriku coast of Pacific NE Japan. That coastline is particularly vulnerable to tsunami waves because it has many deep coastal embayments that amplify tsunami waves and cause great wave inundations. The M 7.6 subduction earthquake of 1896 created tsunami waves as high 38 m and a reported death toll of 22,000. The M 8.6 earthquake of March 2, 1933 produced tsunami waves as high as 29 m on the Sanriku coast and caused more than 3000 fatalities.


The March 11, 2011 earthquake was an infrequent catastrophe. It far surpassed other earthquakes in the southern Japan Trench of the 20th century, none of which attained M8. A predecessor may have occurred on July 13, 869, when the Sendai area was swept by a large tsunami that Japanese scientists have identified from written records and a sand sheet.


Japan earthquake: before and after


Continuing readjustments of stress and associated aftershocks are expected in the region of this earthquake. The exact location and timing of future aftershocks cannot be specified. Numbers of aftershocks will continue to be highest on and near to fault-segments on which rupture occurred at the time of the main-shock. The frequency of aftershocks will tend to decrease with elapsed time from the time of the main shock, but the general decrease of activity may be punctuated by episodes of higher aftershock activity. Beyond the ongoing aftershock sequence, the USGS does not believe that the earthquakes in Japan have significantly raised the probability of future major earthquakes. While the probability of future large earthquakes far from northern Honshu has not increased, neither has it decreased and large earthquakes will continue to occur just as we have observed in the past.

Estimated Tsunami arrival times for locations along the North American Pacific coast





The following list gives estimated times of arrival for 
locations along the North American Pacific coast from a
tsunami generated at the given source location. The
list is ordered by arrival time starting with the earliest.
Since tsunami speed is directly related to
water depth, tsunami ETAs can be computed independent of
tsunami amplitude. THE LISTING OF A TSUNAMI ARRIVAL TIME
BELOW DOES NOT INDICATE A WAVE IS IMMINENT. The listed arrival
time is the initial wave arrival. Tsunamis can be dangerous
for many hours after arrival, and the initial wave is not
necessarily the largest.

Indonesia: New beginnings for young survivors

I spent last week in the Tsunami affected areas of Aceh, Indonesia, where the Red Cross is nearing the end of its Tsunami recovery operation. As I travel about inspecting the work we have done, I hear so many stories from Tsunami survivors. Here are a few of them.



Four years after the disaster, Masrizal and Bahtiar are looking to the future. Along with nearly 500 other young people, Bahtiar is participating in a vocational training programme provided by the American Red Cross and the Indonesian Red Cross

Masrizal is a sensitive and quiet young man. At age 27, he has a strong vision and a desire to enrich himself and help others. But beneath his stoic demeanor lies a moving story of tragic loss and new beginnings.When the December 2004 tsunami struck, Masrizal lost his entire family, his home and all of his earthly possessions in a matter of hours. His village of Lamlumpu, in Aceh Besar, was utterly destroyed and many of its residents killed.“My parents and siblings disappeared in the waves, together with most of the other people who lived in my village,” he says. “It left me all alone in the world.”

Compassionate and concerned

But Masrizal says the experience made him more compassionate and concerned about the well-being of those around him. He says he often thinks of his mother and tries to emulate her. He remembers her as a warm and lively woman who was at the centre of community life.“My mother was always involved in community events,” he says. “She was easy to talk to and I felt like I could tell her anything.”More than a year ago, he received a new house from an international organization near where most of Lampulu's surviving residents have settled. He has also found a job at a local blood testing laboratory, where he works part time.

Badly injured

Like Masrizal, 20-year-old Bahtiar also lost nearly everything to the tsunami. Caught up in the waves, he was badly injured but luckily managed to survive. Unfortunately, both of his parents and five of his siblings did not.“There was nothing left from our home - it disappeared completely,” Bahtiar, who was aged 16 at the time, recalls. “I felt sad and confused, but thankfully I had my relatives to care for me during that time.”His surviving family members helped nurse him back to health and supported him while he completed secondary school.

Sustainable income

Four years after the disaster, Masrizal and Bahtiar are looking to the future. Along with nearly 500 other young people, Masrizal is participating in a vocational training programme provided by the American Red Cross and the Indonesian Red Cross (PMI). The training, which is part of the psychosocial support programme, aims to help tsunami-affected youth like Masrizal to gain the skills they need to earn a sustainable income.“We are allowed to choose the type of training based on experience and interest,” Masrizal says. “Once I complete the course, I hope to earn more money and establish my own business.”Participants can choose from a range of courses, including carpentry and computer skills.

The training, which is part of the psychosocial support programme, aims to help tsunami-affected youth like Masrizal to gain the skills they need to earn a sustainable income.


Masrizal has chosen a course in electrical repair while Bahtiar has selected a mechanical repair course.“I want to continue my education and go to university,” Bahtiar says. “Hopefully the income I earn from being a mechanic will pay for my school fees.”

Incredible recovery

Though Aceh has seen incredible recovery and growth in the four years since the disaster, it remains one of the poorest provinces in Indonesia. Now that houses have been built and major infrastructure repaired, economic recovery assistance is one of the most pressing needs for survivors.With tsunami-related aid from the government and international organizations coming to an end, it is vital that young people have the skills that they need to continue on the path to recovery and self-sufficiency. The training is being implemented in partnership with local government agencies who help identify local experts to act as facilitators and provide professional certificates to participants successfully completing their course.On the last day of vocational training, Masrizal receives an “A” score for the course.“The more skills and knowledge that I have, the better my life will be and the more I can contribute to my community,” he says.

Bahtiar receives his training certificate.


Psychosocial Support Programme (PSP) in Aceh

The PSP programme is working in 160 villages and 139 schools in Aceh Besar, Banda Aceh and Aceh Jaya. After over two years of support in Aceh Besar and Banda Aceh, activities in these two districts are ending while activities in Aceh Jaya will continue through December 2009.To date, 388 community and school facilitators have been trained to design and implement psychosocial activities. 5,624 individuals have been trained in psychological first aid, equipping them with the skills to sensitively respond to the needs of those affected by crisis. It is hoped that these individuals will be able to continue to support their communities in times of need long after the programme ends.With Indonesian Red Cross (PMI) and the University of Indonesia, the American Red Cross is designing and supporting a Master’s degree course in disaster psychology. The first course will begin in February 2009 with 20 students from across the country. As PMI staff and volunteers, these students will trained and prepared to respond the psychological needs of disaster survivors nationwide.

Masrizal proudly display his training certificate.

Finale: I am off to New York tomorrow night, 22 April, to be there for the presentation of the Tsunami Global Lessons Learned Report to the SG of the UN and Bill Clinton who has been his special adviser. It will be great to see New York again. The last time I was in New York was 1986 after going to the North Pole with Will Steger, and I appeared on Good Morning America in Polar bear trousers, seal skin boots, Beaver mitts with a badly frostbitten face. Dan Rather was the host on the show. That night in 1986, after 4 months of isolation, I hit New York town and had quite a party.
