prevention of higher fatalities in the event of a tsunami using technology 

# data[].attributes.body
in Japan, the government installed satellite-controlled gates at the mouth of rivers which face the open sea so that in the event of a tsunami, the gates can be closed against the waves without risking human lives (in the 2011 tsunami in Japan, the firefighters who tried to close the gates manually were swept away by the strong waves and lost their lives.)

- To monitor earthquakes, scientists use seismographs to detect ground shaking.
- drones and robots are used to locate survivors or people stuck under debris caused by natural disasters. These robots and drones will send information to emergency teams to save them.
- Using news services to warn other people from places nearby affected areas
- observation and information technologies improve prediction of severe weather, floods and other natural disasters

1. SERVAL project

Developed in response to the Haiti earthquake. The technology allows mobile phones to communicate directly with each other even when there is no network coverage. TERA (Trilogy Emergency Relief Application) is an SMS text system designed for two way communication between aid agencies and people affected by natural disasters. The technology has been in use since the 2010 Haiti earthquake.

1. NASA Finder

Developed in response to the 2015 Nepal earthquake. This is a suitcase-size device which can detect human heartbeats under 20 ft of solid concrete and 30 ft of rubble.

1. ALIRT (Airborne Ladar Imaging Research Testbed)

Technology that can produce high-resolution 3D renderings of terrain and infrastructure. Thus, it can help identify population changes at displaced persons camps, helicopter landing zones and road travel conditions. This information can help aid agencies to effectively dispatch vital resources, such as tents, blankets, water, food and medical supplies.

1. Radar Sensors

Land-based sensors, including radar sensors, collect similar data along the coastline. This system, called the Web-enabled Awareness Research Network, can help save lives and limit the impacts of natural disasters.

1. Orange Saver

The Orange Saver could help save many lives during a natural disaster. This invention is meant to protect a family during a tsunami. It is large enough to hold four adults and each person can be strapped into bucket seats with five-point safety harnesses.

Detection
- data is collected through underwater sensors which measure a variety of physical and chemical properties including water pressure, movement and temperature

- land based sensors including radar sensors collect similar data along the coastline
- this data helps to detect tsunamis early
- weather data such as air pressure, wind speed, and temperature can be used to make predictions about weather systems

After the event
- robots and drones can help locate and transmit information about survivors to emergency personnel, as well as to transport humanitarian aid

Smart home sensors could possibly detect fires and activate sprinklers in order to put out wildfires and prevent the loss of any buildings, agriculture or other parts of nature that could be affected. For example, a smart irrigation system could detect rising temperatures or smoke and activate sprinklers before a fire can break out.

Helps combine information on natural disasters with information on human activity to determine vulnerability to natural disasters.

- Land-based sensors, including radar sensors
- seismographs to detect shaking and can use a Gutenberg-Richter diagram (seismic sensors)
-Weather satellites can track storm movements to predict hurricane landfall and monitor conditions that would promote wildfires.
- deep ocean tsunami detection buoys
-hazard zones to detect incoming disasters
- wildfires monitored using the emitted radiation in the Thermal infrared part of the Spectrum

In recent times, technology has been employed to fast track disaster relief efforts. For instance, drones and robots have been used to locate survivors and transmit information to emergency teams. They have also been used to drop humanitarian aid.
