Earthquake Prediction Technology

Geologists from all over the world trying to find the right technology to predict earthquakes. From geologist at the National Taiwan University claims that they have discovered an earthquake detector. This device is claimed only takes about 30 seconds to analyze the disaster that will happen.

It also claimed to be able to analyze the size of the earthquake strength and estimate the time of the earthquake happen. By detecting the signs of an earthquake. According to one researcher, Yih-Min Wu, the price of these devices is only 302USD.

This earthquake device used to measure changes in gravity and have not been used operationally to predict earthquakes. So it still have to go through the final stages of testing, ie, connecting to the computer system. These discoveries were also still doubt the experts, because not a single human-made tools that can predict an earthquake.

Earthquake-prone countries have at least four related seismic sensors, such as:

• tsunami early warning system sensors
• seismometer sensor to determine the depth and magnitude quake quake
• GPS sensors to monitor changes in the elastic earth by a seismic event of disruption
• marine tidal sensors

With those four powerful devices, geologist are still difficult to predict the occurrence of earthquakes. This is due to the characteristics and structure of different rocks.

In addition, those devices are also used to monitor the behavior of the earth's crust that is affected the earth constellation of other planets that play a role in triggering earthquakes. Although not yet able to detect when and calculate the power of the earthquake, the data obtained from the devices is expected to be used to calculate the likelihood of an earthquake.

Disaster Management in Indonesia

Tsunami strikes again in Japan on March 11, 2011. After a deadly 8.9 earthquake, one of the largest earthquakes in the history of Japan, a massive tsunami hit the north east coast of Japan.

Indonesia is one of the world's most disaster-prone countries. Now is the time for Indonesia to priorite management disaster.

To get everything that essential about:

• Understand what is a disaster, the loss from it, prevention act, what should we do in a disaster, and also survival act after it.  
• Reduce fatality and loss from a disaster.
• Detection of disaster, avoid its potential threats, prevent its effect in every aspects.
• Better in get over a disaster and helping victims.
• Restore places to normal better and faster.
• More efficient and effective in resources.

Potential Hazards

• Geologically prone to earthquake, tsunami, volcano eruption and landslides.
• Hydrometeorology (flood, flash-flood, typhoon and drought).
• Biology (epidemics, diseases and pest).
• Environment degradation (deforestation, forest fire, haze, water and air pollution).
• Technological failure (transportation and industrial accidents).
• Social Conflict (civil unrest and terrorism).

Policies 

• Strengthen national capability in disaster management, especially in prevention, mitigation and preparedness.
• Manage and mobilize all potential resources (infrastructure and manpower) in disaster preparedness, responds and recovery.
• Empower local authorities in anticipating and responding disaster in their regions.
• Coordinate all stakeholders and activities in disaster management.
• Incorporate disaster risk reduction in the framework of national development plan.

Strategies

• Disseminate disaster risk reduction and strengthen capacity through training and education.
• Prepare disaster legislation, regulations and standard operating procedures.
• Set up disaster management information systems.
• Disseminate hazard mapping and risk assessment.
• Set up disaster management plan in all levels.
• Strengthen National/Provincial/District Emergency Operation Center and Rapid Response Team.
• Strengthen local capacity in disaster recovery. 

Conclusions

Indonesia is disaster prone country, both natural and human induce disaster. Disaster management in Indonesia needs support from space technology in terms of hazard and risk mapping, early warning, damage assessment and rehabilitation. The Asia-Pacific Regional Space Agency Forum or APRSAF play an important role to assist Indonesia in the disaster management.

Japan Earthquake 8.9 magnitude triggering Tsunami

An 8.9-magnitude earthquake hit northern Japan on Friday, triggering tsunamis and sending a massive wave filled with debris that included boats and houses inching toward land.
The number of fatalities was unclear, but Japan's Kyodo news reported at least 10 killed and numerous injured.

The quake prompted at least 19 countries and numerous Pacific islands to issue tsunami warnings. It was followed by powerful aftershocks that were felt in capital of Tokyo.

The quake's epicenter was 373 kilometers (231 miles) away from Tokyo, the United States Geological Survey said. But residents there continued to feel aftershocks long after the quake.

At Tokyo Station, one of Japan's busiest subway stations, people grabbed each other to steady themselves. Children cried. An announcement over the station loudspeaker warned commuters to remain underground.
