When someone write status updates from social media has indirectly been communicating not only what happened to him but sometimes also on what is happening. If the post contains things that are not so important or mundane limited his daily activities are not so influential. but how if it happened at a crucial time, as when a natural disaster, riot or other extraordinary events which greatly affect the activity of the entire society .Thus proving the importance of such interactions.
From tornadoes to terrorist attacks, when an emergency strikes, the people in the affected areas started posting about it in social media, especially from their phones.
Increasingly, emergency response officials monitor these posts to improve their understanding of the situation takes place - and this information can prove very useful when deciding where to deploy response or relief efforts.
At a recent conference, Russ Johnson, director of public safety and homeland security for the ESRI (a leading vendor of geographic information systems, or GIS), describes how the mobile social media is changing the way emergency response and recovery work.
For example, after the earthquake, "there are usually people in the affected areas, including the general public, tweeting or posting to other services," Johnson said. "And for a huge emergency that lasted for a while, often someone makes a crowdsourced map with Ushahidi."
"The field commander may see that the real-time information and realize that they model the situation is turned off so they may decide: .. Let's turn the team into this location here"
The beauty of social media, Johnson said, is that "multiplies your ability to have sensors on the ground to gather information."
However, in an emergency, not all are equally useful tweets. One difficulty with placing social media posts from the public for use in emergencies is that this information is free form and is often incomplete. For example, someone might tweet, "Power lines down," but neglect to specify the location.
Communities can use social media to help emergency response. "If they can provide real information, not just an interesting communication, which is most helpful."
Electrical and data connections will often come down during emergencies, and voice calls (including 911 calls) are not likely to get through, but often the cell network can still bring some traffic SMS text messages.
If you use Twitter, you can set your phone to tweet via SMS. Then - if you can do so without endangering themselves or others - you can try to post useful information about what is happening around you in the back of an emergency.
Do not try to capture every detail - that runs on your cell phone battery, and there may be more important things to do than stand around tweeting. But for critical intelligence, a tweet some keys can alert the authorities and may call for help.
What should tweet immediately after an emergency?
Storing your messages short, clear and specific. Use the keywords you think will look for emergency responders. Location information (city and street names in particular or intersection) is very useful.
If you know the ID Twitter local emergency response agencies, news outlets, or other relevant person or organization, including them as an "@ reply" in your tweets to get their attention. They may tweet or convey your message to the officials.
Johnson suggested mentioning the types of information:
- Power outages: No power environmental Prescott Oakland @ pge4me
- Injuries: Collapsed Greenville apt bldg 40 & Simpson. 2 trapped, injured
- Supplies needed: water, food urgently needed shelter Basic MLK Atlanta @ femaregion4
- Extensive Damage: 600 block of 14 Berkeley St 10 + homes destroyed @ insidebayarea
- Incident status: now the fire within 100 feet of homes end E Jay Rd Boulder
"With the Japanese earthquake and tsunami, mostly out of communication, but it's mostly text messages still get through," Johnson said. "We can learn from the reference in which the primary power outage Then we use GIS technology to transform information into 'hot spots' for emergency response .."
Emergency response community is developing tools to better filter out social media during emergencies. "It's a real challenge, try to take unauthoritative information and make it trustworthy, reliable, and actionable," said Johnson.
Mobile technology also help emergency responders communicate better among themselves.
After the disaster, one of the biggest job is damage assessment. Usually this is done with paper forms filled out in the field, or perhaps on the basis of a tablet or PDA. That takes time to get the information back where it's needed.
But, Johnson said, "Imagine you're walking through town the day after the tornado hit big, and road signs and landmarks are all gone You do not know where you are. But your smartphone has GPS, can tell you the address where you are then a application forms can appear, and the location is filled There is a select list that you can quickly choose from -.. said, to describe the damage as destroyed, moderate, or mild damage. You can take pictures and you can send information back soon .. And 50 others do the same. Anybody can do it, you can easily train volunteers to do that. "
And if there is no access to wireless networks, phones or tablet will store and transmit data when the connection is restored.
Using the same tools, the respondent and workers can also report back problems have been fixed - such as downed power lines removed, the fire extinguished, supplies delivered, or the people rescued.
This type of tool has changed the "latency map" that interfere with recovery efforts. "This standard has been that the incident command post that you update your operating map about every 12 hours with the type tool, you update your map of every hour .. It can make a huge difference, saving many lives, and help keep people out of danger."
Of course, not every emergency is a big disaster. Every day in every community a smaller emergency occurs: house fires, car accidents, heart attacks and more. Police, fire, and ambulance personnel can also use the information more when they raced out to where - information that local governments and agencies often already have, but can not be easily shared.
For example, Johnson observed that many firefighters get injured or killed by falling through the floor. "Just being able to quickly scan the floor plans and see a basement that could change the way you enter a burning building," he said.
"The agency has been collecting data, but it's one-way street, and generally do not come out for first responders include such things as inspection reports of facilities, location of hazardous materials and utility boxes -.. And where people are generally Right now, if the first responders have access to information at all, usually back at the station or in a three-ring binder thick and fast this should be easy to access .. "
In some big cities like Phoenix and Los Angeles, local governments are taking the lead to get this kind of information to first responders in a meaningful manner. "So far the technology is not perfect, but you should have any kind of data flow when you have a large number of critical infrastructure and the built environment is complex."
For many city governments and emergency response agencies, the main challenges to effective information sharing in the field is culture, not technology. And often the responders who rejected.
"They do not want to be bothered by or overloaded with information they simply want to focus on saving people and putting out fires .. So, you have to really be careful about what information you are serving them, and how they interact with it," said Johnson. "But once they see what this information could be done, they usually want it."

Survivor: Gunman screams 'we all shall die' during shooting spree
July 23, 2011 5:13 a.m. EDT
How important is Social Media through smartphone or else for Emergency from individual, society and even more global
Oslo, Norway (CNN) - A young man who survived a two-hour rampage of armed men in Norway Utoya Island said he was still alive because he played dead, grabbed the body around it, the account came as authorities raised the death toll on Saturday from the previous day to 84 attacks .
Adrian Pracon account provided the most obvious detail to date of the shooting attack Friday at the youth camp of the ruling Labour Party who police said killed at least 84 people were killed. The attack came shortly after an explosion in the capital, Olso Norway that killed seven people, increasing the number of deaths in the two attacks combined for 91.
"I and the other two bodies lay, and survived because we survive and pretend that we die," said Pracon CNN Saturday morning by phone from the hospital.
"I could feel his breath," said 21-year-Pracon. "I could hear his boots."
Norwegian television and newspaper reports have identified a suspect in the attack as 32-year-Anders Breivik Behring.
Police have not released the identity of the man, told reporters on Saturday they arrested a man 32 years old Norwegian who was questioned in the second bombing and shooting attack in Olso youth camp on Utoya Island, about 20 miles from the Norwegian capital. Police spokesman told CNN Is Frykholm Saturday that the government is investigating further, based on information supplied by the person in custody.
Campers were shot on the island described the rower Utoya Utoya rescue survivors: "I'm glad I'm alive 'Norway Norway FM shock at the attack
"The question the official start now. He will be charged for both bombings and killings," said Roger Andresen, a police official, a journalist during a press conference. The suspect with the police, making it clear that he wants to explain himself, says Andresen.
A victim who was shot during the attack on the island told CNN Saturday that he had seen pictures Breivik taken from what is believed to be her Facebook page and displayed on a television station NRK and TV2. The victim said he recognized him from news reports the gunmen.
Prime Minister Jens Stoltenberg does not exclude the possibility that there is more than one person involved in bombings and shootings that killed at least 87 people were killed.
"They have so far arrested one person," said Stoltenberg reporters Saturday. "They have not concluded whether there are one or more than one person behind the attacks."
That attack and big explosions that targeted government buildings in the heart of Oslo related, police said.
Seven were killed in the blast, said Frykholm. Overall, 90 people were hospitalized as a result of the explosion, said Erik Hansen, a spokesman for Oslo Mayor Fabian Stang.
It was while the authorities were looking for survivors of the bombing of the mid-afternoon in Oslo that a man wearing a police uniform and identifying themselves as officers arrived by boat on the island Utoya, where the word spread among the campers about the explosion in the capital, Pracon said.
The 700 adolescents and young adults attending the camp gathered in the large conference room where the organizers of the camp to share information about the bombings in Olso when police asked if he could address the group, Pracon said.
"We, of course, allows him to come" and address of the group, Pracon said.
At that time, Pracon said, the man started shooting.
What followed, Pracon say, panic and chaos as some campgrounds run from the shooter, while others go towards that person because they believe it is a drill or test.
Many who escaped ran to the beach, jump into the water to try to swim three-quarters of a mile of water between the island and the mainland.
Pracon among those who tried to swim, but was forced to return.
"I felt I could not breathe I've swallowed too much water .. I have also jumped because I was the last person to walk to the beach of this person. So I do not have time to take my clothes off. As I'm swimming, I find it interesting clothing I lost because of their heavy boots, clothes, "he said.
"... I'm not sure if I'll succeed because I was tired."

Labour Party member Bjorn Jarle Roberg-Larsen told CNN that the man said he was camping there to carry out security checks.
"After just a few minutes, he took the gun and started shooting people," said Roberg-Larsen. "A panic broke out, people try to hide, some jumped into the water and tried to swim ashore."
Others took refuge in caves or bushes, or climbing trees. "And he went after them," said party member. "Unfortunately, many people are injured and also a lot of people who die."
Pracon said the gunman chased someone into the beach, shouting at them when he opened fire on them.
Pracon lying on the beach when gunmen opened fire on them in water and on shore.
"I was maybe 5, maybe 7 feet away from him because he yelled he would kill you all and we're all going to die He pointed his gun at me. But he did not pull the trigger," said Pracon.
"He left and came back maybe an hour later ... he shoots almost everybody I and two other lay and survived because our bodies can survive and pretend that we are dead .."
Authorities are looking for Saturday waters around the island, looking for camping body that may have drowned trying to swim to safety, police said.
Frykholm, a police spokesman, said that the man was arrested on the island seems to fit the description of someone seen near the government building shortly before the bomb exploded.
The man, whose identity has not been released by authorities, it does not work for policemen, Frykholm said.
The prime minister, whose office was badly damaged in the explosion of Oslo, Norway led the Labour Party, which runs youth camps, where about 700 people attended on Friday.
Acting national police chief, Sveinung Sponheim, told reporters in Oslo that the guns are automatic weapons and explosives found undetonated on the island after the attack.
Most of the Labour Party youth movement participants aged between 16 and 22, though some were as young as 13 and as old as their early 30s, Roberg-Larsen said. They had planned to attend training classes and participate in the activities of political groups during the day and sleeping in tents at night, he said.
Citing the Norwegian broadcasting, he said that the man was stopped by Norwegian police.
Roberg-Larsen said the nearest hospital to ask donors to give blood type O, the most common type.
"It's a bad day for Norway," he said. "We never had a terrorist attack on Norwegian soil before Today, we have two. So people are really surprised."
Foreign Minister Jonas Gahr Store, a member of the Labour Party, said he visited the camp on Thursday. "There is a political discussion, there is joy, there is everything to do with political youth camp."
He said that the fact that the suspect is a blond Norwegian man should underscore the importance of allowing the police to do their work before drawing conclusions.
"We have seen in Europe in recent years that politicians have jumped to conclusions about the suspect before the investigation has been done, and we will not make that mistake," he said.
Stoltenberg, prime minister, was not in office when the blast and was unharmed, officials said.
Stoltenberg, who has been prime minister since October 2005, the head of a coalition government consisting of the Labour Party, Socialist Left Party and Center Party.
After that, he had a message to anyone who may have been responsible: "You will not destroy us," he said. "You will not destroy our democracy We are a small but proud nation .. No one can bomb us to dwell. No one can scare us from Norway. This evening and tonight, we'll take care of each other. That what we do best when under attack. "
Nick Soubiea, an American-Swedish tourist in Oslo, said he was less than 100 meters from the blast, described as deafening. "It was almost in slow motion, like a big wave that almost knocked us out of our chairs," he told CNN. "It's very scary."
Several buildings in Oslo on fire, smoke rising from them, he said.
The blast also damaged the Ministry of Oil, which burned.
In brief remarks to reporters from the Oval Office, President Barack Obama extended his condolences to the victims of violence in Norway, said the incident was "a reminder that the entire international community has a stake in preventing this kind of terror from occurring."
British Foreign Secretary William Hague also condemned the attack.
"We condemn all acts of terrorism," he said. "The UK stands shoulder to shoulder with Norway and all of our international allies in the face of such atrocities."
