Predicting eruptions in the Masaya Volcano with wireless sensors

Volcanoes are one of the most unpredictable and impressive natural phenomenons. Worldwide researchers and scientists have always been trying to discover what happen inside volcanoes to predict future eruptions that will save lives. Their activity has provoked along years great disasters destroying entire settlements with lava flows and also endangering the environment or human health due to gas emanations or ash falls.

Some vulcanologists are currently focused on working with the latest technology to monitor in real-time everything that happens inside and outside the crater to predict eruptions. Qwake, a global brand that merges ground-breaking scientific expeditions with cutting edge technology to drive positive change, has trusted in Libelium technology to develop a wireless sensor network in the Mouth of Hell, Masaya volcano in Nicaragua.

Masaya is one of Latin American most active volcanoes. In fact, in 2008 during September, November and December the caldera threw ash and steam rising a height of 2.1 kilometers. At this time, there is a lava lake in one of the craters with 600 m2dimension that offers an unprecedented glimpse into the dynamic behavior of magma plumbing system including cascading as explosions, emission of lava jets, etc.

Qwake team, with explorer and filmmaker Sam Cossman, Nicaragua government, Libelium and General Electric (GE) have worked in this project to bring the first volcano online. The expedition took place along July and August 2016. The team was looking for a wireless monitoring system able to collect, transmit and store data in real-time. For this reason, they chose Libelium to get information directly from the crater.

In order to access safely to Santiago Crater, the open air lava lake, Sam Cossman and his expedition team developed a zip line system to solve some previous challenges and efficiently descend personnel and gear there. It allowed to install the Waspmote Sensor Platforms next to the crater to get data in one the most extreme and challenging environments.

The Sensor Platforms deployed in Masaya volcano were Waspmote Plug & Sense! Smart Environment PRO and Waspmote Plug&Sense! Ambient Control as data repeaters. Sensors connected to Waspmote Plug & Sense! Smart Environment were more than 80 and measured CO2, H2S, temperature, humidity and atmospheric pressure.

The encapsuled sensor platforms were vacuum-sealed to be protect against the heat inside the crater and also in areas next to the volcano. There were around 150 degrees Farenheit (about 65 Celsius degrees) where most of the sensors will be placed, although parts of the active volcano reach 800 to 1,000 degrees Farenheit (between 426 and 537 Celsius degrees).

Waspmote Plug & Sense! Smart Environment PRO sent information directly to Meshlium Gateway and in some cases to Waspmote Plug&Sense! Ambient Control when there was low signal acting as repeater stations. This data was sent through XBee900HP. The IoT Gateway collected data and sent the information through 3G to GE database were after was visualized in Predix, a cloud-based software platform GE developed for the Industrial Internet.

One of the explorers from Qwake, Hugo Nordell, explained the benefits of using Libelium technology in Masaya volcano project: “Our team was able to quickly setup and ensure that data was captured correctly. This allowed us to focus on solving actual problems related to deploying the sensors inside the crater and bringing the Masaya volcano online, rather than having to deal with connectivity and underlying data transfer”.

Public service by saving lives and opening data

The main aim of the project has been building a digital early warning system to predict volcano eruptions. This information will be used by researchers and data scientists to build a family of “digital twins” to simulate digitally what is happening inside the cater.

The vulcanologist who has participated in Qwake project, Guillermo Caravantes, has been widely researching about Masaya. He has explained that it represents “a real danger” for inhabitants from villages next to the volcano. “We could potentially have millions of lives at risk. It could happen at any time and the problem is that we are not able to predict when this could happen or what sorts of signs from the volcano”, asserted Guillermo Caravantes, vulcanologist from Qwake.

The ultimate goal of the project is providing a public service by giving access to the general population and decision makers enabling them to experience an active volcano in real-time. The predictive analytic tools built on the cloud-based platform uses a combination of data gathered over more than 20 years of fieldwork at Masaya and also information gathered by the sensors connected to Waspmote Plug & Sense! Sensor Platforms installed in this project. All this data will help to anticipate volcanic crisis, and act as a pioneering, first-of-its-kind Early Warning System. After this project, the expedition believes that there is potential for huge applications in worldwide volcanoes.

Controlling shipping traffic in the Dutch canals with wireless sensors

dsc01528

In t the Netherlands there are many waterways, small inland harbors and canals that are used by citizens in their daily routines. Each city has a water infrastructure with high-density shipping traffic. For municipalities, provinces and other potential canal authorities such us Ministry of Infraestructure, it is essential to provide a system able to control the amount of boats that sails in an area an also automate the opening and closing systems of the bridges.

 

Vicrea is a dutch company specialized in Smart Integrated Information and Geographic Systems and Smart City solutions. The company has developed a wireless sensor network with Libelium technology to manage canals traffic in the Netherlands by controlling the flow of boats.

Innovative laser solution to detect ships

This solution arises with the objective to know the amount of ships that sails in the canals and also their direction to plan the water infrastructure. It has been already deployed in some of the most touristic and well-known cities from the Netherlands: Delft, The Hague, Leiden, Alphen aan den Rijn and Gouda.

There is a wide range of boats that sails on the canals: cargoboats, commercial passenger ships and recreational ones. Although it was known by public authorities and citizens that in specific times there was heavy traffic, there was not any knowledge and neither control to solve this problem. “Libelium helped us in an innovative and professional way to help our project to become a success”, affirms Erkan Efek, Business consultant & Architect GIS of Vicrea.

Vicrea and Libelium have worked in developing a new and innovative laser solution that is able to monitor direction, distance and speed. This sensor allows to detect any ship that is crossing by a concrete point and also to know the direction towards the ship is sailing.

The shipping traffic data monitored by the sensors added to Waspmote Sensor Platformsis sent out through Zigbee to Meshlium. 868 Mhz wireless technology is used to connect the gateway with Vicrea Cloud Platform based on Microsoft Azure SQL Database. From there, data can be further distributed to a live monitor or can be stored for later analysis and prediction.

 

The solution developed between Libelium and Vicrea will help public institutions to manage the water infrastructure and also control other issues. With this deployment, there will be possible to know if the maintenance level of canals is at par with traffic density in a canal. Bridge opening and closing will be automated to improve cars and ships experiences and also to reduce waiting times. The platform will control if a boat is entering in a private or prohibit area.

This monitoring system will be working 24 hours a day, 7 days a week, to give public authorities a holistic view about what is happening in their water infrastructures. Erkan Efek, Business consultant & Architect GIS of Vicrea, has highlighted that “the solution incorporates cost-effective elements and eco-friendly parts. We use solar panels for our power supply and send data wirelessly”.

Sensors can be placed anywhere so each government can choose depending on the needs and the urban planning of each city. Knowing in real-time information about traffic congestion or predicting maintenance for bridges are just some of the improvements that councils can apply in their strategies for water infrastructures management.

The deployment has reached the goals that the companies settled since the beginning. Data related with passing ships and also frequency will be monitored with high accuracy, costs will be drastically reduced, about 80.000 euros each year per bridge, and the system will be working with no interruption.
