In the United States alone, nearly part of the population lives in quake-damaging tremor-prone spaces, according to the United States Geological Survey (USGS). Globally, populations in seismic risk zones have increased exponentially in recent decades. For others to have time for themselves of seismic events, some countries have built complex earthquake early warning (EEW) systems.
Once that network detects an earthquake and sends an alert, giving other people time to move to a safer location. However, the formula structure (EEW) is an expensive company. The structure of Japan’s early precautionary formula charges about $1 billion. Building such a formula for the west coast of the United States would cost about $40 million, with maintenance prices and consistent with a total of more than $16 million consistent with the year, compared to others.
A new open source seismology mapping known as OpenEEW is bringing a cutting-edge technique to classic seismic tracking and caution systems. With IBM, the Linux Foundation, and others, OpenEEW aims to create a network of sensors to help with an immediate and affordable earthquake reaction around the world.
Since the beginning of 2018, software and hardware company Grillo has been its EEW formula in Chile and Mexico to monitor seismic activity and transmit alerts. With Grillo sensors, cloud-based algorithms are fed through the knowledge of the uncooked accelerometer to monitor seismic activity. If an earthquake is detected, an alert is sent via Twitter and the Grillo app.
Recent advances in IoT technologies, cloud solutions, etc. have enabled Grillo to cost-effectively implement opportunities in popular EEW technologies. As a result, Grillo can benefit from more cost-effective seismic sensors than researchers implement for earthquake monitoring.
“In the case of the West Coast of the United States they use lab seismometers that charge $20,000 or more, and that’s because they are seismologists who also use them for research. In our case, we don’t care. Magnitude two earthquakes, we only need five, six and seven, so we have much more stupid sensors and yet they do the task very well,” said Grillo founder Andrés Meira.

Earthquake tracking is about filtering through a wealth of knowledge and environmental noise to identify seismic activity. Instead of activating those sensors in more rural spaces around cities to make certain blank readings, Grillo has placed those parts in buildings through urban environments, leveraging algorithmic systems in the cloud to clear the city’s rumble.
“We have very intelligent algorithms that eliminate noise, so other people pass, the doors close, the cars pass. We know that these are not earthquakes in our software, and this is a big challenge because the other examples in the world seem to be for those blank sites where there is no ambient noise. We don’t care much about that, ” said Meira.
Once a station confirms a possible earthquake amid the noise of an urban environment, the formula expects other formulas to validate the earthquake, cutting off the threat of false positives according to Meira. However, Meira also discussed the use of device learning to allow earthquake confirmation based on site readings to await confirmation from nearby sensors.
Even multi-million dollar seismic follow-up occasions can be designed with their own inherent flaws and potential blind spots. A national formula is based on the economic, political and social points of a specific government; as Meira noted, “earthquakes respect borders, political boundaries.”
“In the case of Mexico, earthquakes in Guatemala Chiapas in southern Mexico. Again, in northern Mexico, earthquakes in California Mexico and earthquakes in Mexico California,” Meira said.
Unlike a national seismic platform, the team’s EEW open source mapping is designed to create a global component rather than a nationalized network, allowing others around the world to deploy those systems in their communities as a component of a broader humanitarian mosaic of sensors.
“The challenge here is that no national system, administered by a government, will not be able to help others. Therefore, you are blind [to] some of the occasions that are [a] threat to you. So the concept of Open EEW is to allow systems to be built on a citizen-based basis where other people can simply implement their own networks and everyone is helping each other here,” Meira said.
IBM deployed two sensors in Puerto Rico, one in the northeast of the island and the other in the southwest corner, according to Krook. On Thursday, August 6, the day before our interview, Daniel Krook, technical director of IBM’s Call For Code program, said the seismic formula detected tremors when an earthquake hit the island, and the alert was transmitted to Twitter.
“We can compare the two positions to see how the tremors move and we can also see this tracked. Last night in Puerto Rico, there was a magnitude 4.8 earthquake and to see that it was already working through generation and sensors. Deployed in partnership with Grillo is exciting,” Krook said.

OpenEEW follows PAST IBM “technology for good” mappings, such as the Global Challenge Code Call. In 2018, the OWL assignment won the Call to Code Challenge. The cloud-based tool is designed to facilitate communication and logistics in crisis scenarios.
The OWL mapping uses “DuckLinks” (a mesh network of IoT parts of the Internet of Things) to improve communication between others and the first to respond to disasters. Interestingly, there may be a possible overlap between the OWL and OpenEEW mapping.
“What Project Owl has done that can be complementary with Open EEW is that currently, the EEW Open requires an Ethernet or WiFi cable. Then Project Owl solved those problems with batteries, solar power and long-range radius, LoRa. So there are forward-looking tactics for any of the projects to collaborate on an unusual platform, which is exciting,” Krook said.
