is receiving up to date real-time data with accuracy, localized information on air and surface
temperatures, to help in the gritter area decision taking.
This exciting innovative project enables the Hampshire County Council to conserve their
natural resources. It could also change our view of focusing on the issue of when to grit the
road. This project is not only a great money saver but also reduces the carbon footprint of the
local authority.
The formation of the volcanoes is the result of natural phenomenon. A volcano takes place when the
hot molten rocks and gases trapped under Earths’ mantle slices its path through the crust. There are
di erent kinds of volcanoes across the planet. Some are explosive in nature, while some stay non-
explosive. Often the volcanic eruption can take place suddenly, it is very hard to predict about their
eruption in advance. Many scientists around the world are trying to study volcanoes in order to predict
future eruption to save countless lives. A volcanic eruption could destroy entire human and animal
settlements with hot lava fl ows. This could endanger the environment and human health, the gas
emanations and ash falls have catastrophic e ects on our environment.
Experts are also considering to work with the latest technology to monitor the volcanoes in
real-time to learn what is exactly happening inside and outside the craters of the volcanoes. This
might greatly help them to predict the eruptions. Qwake is a global brand that is emerging with its
astonishing scientifi c researches along with state-of-the-art technology to bring positive change.
They have been using a smart platform to establish a wireless sensor network. This project took place
in the Masaya volcano in Nicaragua.
Masaya is known as one of the most active Latin American Volcanoes. The volcano threw ash
and steam rising to a height of 2.1 kilometers in 2008. During this eruption, a lava lake was created in
one of the craters with the huge size of 600 m
2
. This gave a view of the dramatic behavior of magma.
Real-time Monitoring at Masaya Volcano with 80 Sensors
The Qwake team along with Sam Cossman a fi lmmaker and explorer had worked together in this
project to make it the world’s fi rst online volcano. Their mission took place in July and August 2016.
The Qwake team was determined to fi nd a wireless monitoring platform, which is capable of collect-
ing, transmitting, and storing data in real-time. For this reason, they chose a smart sensor platform
for the project. David Gascon a member of the expedition and also the fi rst person to experience the
impressive landscape around the Masaya volcano. He said that they are glad to help in a project that
could potentially save a million lives not just in Nicaragua but also in other worldwide projects to
monitor other volcanoes.
To reach the Santiago Centre and the open-air lava lake safely, their team built a zip line system
that would allow the personnel descend e ciently with gear. They had installed the smart sensors just
next to the crater to obtain information in some of the most challenging and extreme environments.
