Introduction

The story that comes to my mind is, naturally, the things we are facing right now: the earthquake, tsunami and their consequences, including but not limited to the nuclear power station failure. This report tracks the role of the internet and other communications services during the disaster. 

Earthquake, tsunami and nuclear power station damage

On 11 March 2011 at 14:46 p.m., an unprecedented earthquake hit the eastern half of Japan. In less than ten minutes, the first waves of a tsunami arrived on a scale that no one in Japan ever dreamed of. The magnitude of the earthquake was first said to be 8.4 and then changed into 9.0 on the Richter scale, the largest in the recorded history of Japan and the fourth highest in the world. 

The maximum reach of the tsunami was more than 40 metres above sea level – at least three to four times higher than most experts had anticipated. Successive waves of seawater washed away almost everything within one to six kilometres from the coastline, affecting over 30 cities and towns in six prefectures, spanning more than 500 kilometres along the coastline. As of 5 August, the death toll had reached 16,050-plus, and the number of missing more than 7,780. A total of more than 23,800 people were killed in the end, the highest loss from any disaster since World War II in Japan.

The tsunami also hit the Fukushima Daiichi nuclear power station and destroyed the regular and emergency cooling systems. On 12 and 13 March, explosions occurred at three of the four units due to the high temperature of the reactor’s core, and a huge amount of nuclear contaminants were released into the air. More than 200,000 citizens inside a 30-kilometre radius from the nuclear station evacuated with bare minimum belongings, hoping to return within a few days. They were still in shelters and temporary houses or staying with friends and relatives after four months.

Preparation was less than needed

Japan is well known as the land of natural disasters, not only for earthquakes and tsunamis, but also typhoons, landslides and volcanic eruptions. All these happen frequently in any part of the archipelago. The central and local governments have disaster management divisions, armed with heavy equipment and conducting regular exercises. We thought we were prepared. Unfortunately, that was not the case this time.

To be fair, almost no one expected that an earthquake of this scale and magnitude would occur. There were predictions and warnings of a large earthquake within the next 30 years, but most expected less than 8.0 on the Richter scale. The Kobe earthquake in 1995, which killed more than 6,400 citizens, had a magnitude of 7.3. Simply put, the preparation was far less than needed.

The role of the internet and ICTs for disaster relief

Information plays a critical role in organising rescue, relief and reconstruction work for all social disasters. The so-called Great East Japan Earthquake was no exception. Yet the very information badly needed by the citizens in devastated areas was not available in the aftermath. 

It is perhaps one of the first massive disasters that hit a well-developed country equipped with broadband and 3G mobile networks and other information and communications technology (ICT) infrastructure and services. Many citizens were using the internet and smartphones in addition to the conventional mass media such as TV and radio broadcasting to find information or call for rescue. However, most telephone lines where inaccessible. Given the massive call demand from people immediately after the quake, telephone operators blocked 90% of calls in the most devastated areas – a standard practice to ensure that critical connections, such as those used by emergency services, could be made. However, this also meant that many citizens could not talk to their families and friends for hours, and even days in some areas. 

In coastal areas, the tsunami waves destroyed most physical infrastructure – roads and railways, telephone and power lines and radio towers. These areas became “information black holes” and that continued for a week to a month or even longer. 

The government rescue team had 1,500 radio and satellite mobile phones and other communication devices. But these did not meet the demand for communication, and many could not be delivered to local governments, whose city halls and buildings had been severely damaged or lost. Many people tried to use Twitter, email via mobile phones, social networks such as Facebook or Mixi (a popular service in Japan) to ask to be rescued, for food, medicines or blankets – and some of these messages reached people outside the affected areas who managed to provide the relief needed in time. 

Yet the actual usage of internet and ICTs in the devastated areas was very low. The reconstruction work on communications infrastructure started immediately after the disaster, but the sheer amount of damage placed a heavy burden on the infrastructure providers. The pace of reconstruction was slow compared to the massive demand. There had been little policy coordination framework among ICT players for disaster management despite Japan’s frequent exposure to natural disasters.

Many actors started voluntary information-sharing services through the internet. Using Google, Yahoo and Mixi, lists of shelters and missing people, services that matched demand, and data on roads that were passable were set up. Teams went to the affected sites and started to help set up access facilities in shelters or local government offices and schools. Most of this work was ad hoc. 

A number of concerned ICT professionals started a voluntary and pro bono information support platform called iSPP, drawing on industry, government and civil society. This multi-stakeholder platform coordinated and complemented official relief work. We asked ourselves, “What can the internet and ICTs do for the victims there?” It was late, but we thought it was never too late. 

In early April, a number of iSPP members organised a site visit to three prefectures to find out what kind of information and services were really in need. We spoke with local citizens, government officials and ICT professionals who were all seriously affected by the disaster.

The stories we heard were horrible, to put it lightly, especially in coastal cities. When we arrived there, we lost our voices. We just could not imagine what to say. Then, one finds oneself challenged. You must say something. You must act.

Homes that were washed away and ended up at the foot of a hill where we stayed at my friend's house. No search and rescue operation had been performed there yet after three weeks, on 3 April 2011.

A large ship landed 700 metres away from the pier (picture taken 3 April 2011). You can see the same ship from a Google Earth photo: 38°54'56.99"N, 141°34'51.10"E

After the visits, we identified several areas to organise projects around: 

• Provide ICT solutions to recovery works – computers, communication devices and people. 

• Build common application programming interfaces (APIs) for informational support. 

Coordinate NGOs.    


 

• Facilitate information matching for relief work (goods and people).

• Support local government – coordinate with prefectural and central governments to restore their ICT services for victims and citizens. 

•         

Conduct a survey of people’s informational behaviour (how they use and disseminate information). 



To be frank, it was not easy to organise all of this work with limited resources. However, iSPP managed to develop some of the projects. 

How did people use ICT services during the severe disaster? 

There were mixed reports about the actual use of and demand from people for the internet, mobile phones, Twitter and other social network services. In metropolitan Tokyo and the surroundings, where the earthquake also hit, shutting down most trains in the afternoon and evening, many people used mobile phones and the internet: email, Twitter, Ustream, YouTube, Google and Facebook. These were, we thought, mostly used in the Tokyo area, but not in the heavily damaged and devastated areas of the Tohoku region.

Later, in early April, when we organised a field visit to the Tohoku region, including the cities of Iwaki, Sendai, Natori and Kesen’numa, to see what exactly happened, many people we met told us stories that were different to those we had heard in Tokyo, confirming our expectations. These were some of their comments: 

“None of the digital or analogue media worked at all.” 

“Mobile phones were just useless. I tried to call my family members to find out if they were okay. But it didn’t connect. When we got through, busy signals were the answers.” 

“Eventually we lost battery power. Since the main power lines were totally down for days, we could not recharge the power, and so within a few hours, we lost it.” 

“TVs? Come on! When there is no electricity, how can you get to see the TV programmes?” 

“Twitter? Facebook? You are kidding! We were simply not in that mode. Just stunned by the horrible situation; watching the tsunami waves, could not do anything.”

To be fair, all the stories, both about what happened in Tokyo and what happened in Tohoku, were largely true. But they were just many tips of a large iceberg, we felt. 

A survey on people’s information behaviour 

Because of this, a survey on people’s informational behaviour was carried out by iSPP in July. It was a combination of a web-based online questionnaire, which received 2,815 responses, and personal interviews with 186 interviewees, both conducted with respondents in the devastated areas. The questions were as follows:

• Which tools and media were useful? Which were not?

• Which information resources did affected people rely on?

• Were there any differences given the different locations of the disaster?

• Was internet or Twitter really useful?

• What kind of lessons can we draw from this?

The respondents were residents of three prefectures in the Tohoku region: Iwate, Miyagi and Fukushima. All have coastal areas where the tsunami hit heavily and inland areas where the earthquake hit badly, and people in Iwate especially were also exposed to the danger of the nuclear contamination. There were 5.7 million residents in these three prefectures. 

To our knowledge, this was the first attempt at a sizable survey conducted inside the devastated areas in terms of finding out people’s informational behaviour.

At the time of writing, we are still processing the data and writing the full report, but some of the early findings from the online survey have been released already. Here is the summary.

Information devices available to affected people

First, we asked which devices were actually available to affected people. According to the 2,815 people who responded to the online survey, a sharp drop is seen in the usage of most communication devices right after the quake: only 37.5% said they could use mobile phones, from 63.6% usage before the earthquake/tsunami hit them. Similarly, 33.4% could watch TV compared to 87.2% before the disaster, and 19.5% could use the internet compared to 81.3% before the event. The only exception was radio – 67.5% of respondents used a radio within a few hours after the quake, an increase of 20 percentage points over regular use. 

Up to one week after the earthquake, radio (75.0%) still remained the most available medium, while TVs (71.2%), mobile phones (54.7%) and internet (52.8%) showed good recovery, even though they did not reach the level of availability before the quake. 

It is said that up to 72 hours is the most critical period to save the lives of people affected by disasters. Yet as the survey shows, most information channels were not functioning sufficiently during this time. It was extremely difficult to determine the exact degree of damage in the coastal areas, which span 600 kilometres. The police, army and fire and rescue departments all dispatched the first emergency teams, but we knew that the communication lines became more dysfunctional as you approached the affected areas.

It was only in late April, after more than a month, when most major telecommunication operators announced that the repair work on their trunk lines and telephone services was almost done.

The results of this survey corresponded with that: the use of most communication tools and services was recovered between one to three months after the quake. 

Useful information sources

Next, we asked which information sources people actually recognised as useful. By information sources, we meant not only TV, radio, internet and telephones, but also newspapers, email and SMS, word of mouth, community notice boards, amateur CB radios, etc. We meant all forms of information sources.

Here again we found that 67.4% of the people in the devastated areas responded that radio was most useful within a period of several hours after the quake. This was followed by TV (32.1%) for those who still had a power supply, and then “one-segment” digital broadcast TV (a TV service that can be received from a mobile phone or car navigation devices using butteries). This is a reflection of the fact that electricity was not available to many. Word of mouth was ranked seventh, after newspapers. 

Internet services, newspapers, email, mobile phones and fixed-line phones were all under the level of usefulness before the quake.

After a week, TV returned to first place followed by radio, the internet and newspapers. 

Action steps

Many people we interviewed emphasised the importance of power supply in an emergency situation. As we have entered the digital age, almost all devices and services are designed to use electric power. But that could become the major source of vulnerability once a large-scale natural disaster hits a technologically advanced society. ICTs can only work when a sufficient supply of electricity is guaranteed.

Of course, super-large-scale natural disasters such as the 9.0 earthquake or a massive tsunami could destroy almost all manmade infrastructure and devices/equipment once it hits land. However, there are always areas outside the devastated areas where people could start to do rescue and relief work. They can bring in resources needed. This time, what we found was a lack of preparedness for organising the rescue work using ICTs. 

Though we have benefited much from the use of the latest technologies and services such as Twitter, Facebook, YouTube, to name a few, no well-structured information-sharing mechanisms were ready. At best, it was ad hoc. 

Japan is well known for the heavy concentration of all kinds of natural disasters. As I said, it was predicted that at least a 7.5 to 8.0 level earthquake would hit the Tohoku region with 99% probability within 30 years since around 2003. The western and southwest parts of Japan also received a formal alert for an earthquake and tsunami. The Great Kanto Earthquake that hit Tokyo and killed more than 100,000 people, mostly by fire, occurred only 70 years ago. Preparation is the responsibility of policy makers and practitioners using ICTs. And Japan is not the only country subject to such large-scale disasters.

In this regard, we foresee a need for building an international alliance of disaster relief teams. We were told that several international activities were already in place and learned that ICT services for emergency rescue were organised in Thailand and Indonesia in 2004, in Haiti in 2009, and for the recent earthquake in Christchurch, New Zealand this year. We have not teamed up with these efforts in Japan, and because of this we had fallen behind, despite the experiences from the Kobe earthquake and several other disasters in Japan. 

Things are never too late. We should start now.
