Could Earthquakes Have Early Warning Time Found To Save More Lives?

A team of geologists has discovered probable early evidence of massive earthquakes. The current study recommends that the revealing seismic pattern displays a range between 10 Seconds and 15 Seconds of tremor during the seismic event. The researchers have found this sign as a warning indicator after investigating the GPS records of the highest ground displacement taking place at the time of dozens of earthquakes. The complete examination of many of the GPS databases showed that there is a point of time when the start of a particular earthquake takes the shift into a slip pulse, which is the mechanical operations that scale with the magnitude.

The journal Science Advances has the current study published with all the details that help differentiate between small plus medium-sized earthquakes and large or extra-large quakes. The pattern was found to be consistent. According to Professor Diego Melgar at the University of Oregon, the databases were created diversely; hence studying the patterns was quite interesting. The researchers have found the displacement acceleration to be somewhere between 10 Seconds to 20 Seconds at the start of 12 major earthquakes that will be occurring from 2003 to 2016. Thus, even though the GPS devices are not preferred in case of the earthquake warning systems they have many applications in the land-based faults around the world. Many of the fault lines across the world have the GPS instruments installed and connected to the huge Cascadia subduction zone located in the Pacific Northwest.

There are GPS stations on land located on the coasts of Washington and Oregon; however, they give delayed information. The time the earthquake begins to move, the GPS shows a delay in passing on the motion information onto the coastal stations. This delay does have an impact on the warning signal and the coastal people have no warning as they are in the blind zone. The researchers Melgar and other geologists from the US and Japan are working on innovations that can monitor faults on the seabed. Melgar’s previous research had determined that the data obtained could help add more 20 Minutes of warning period during the tsunami.
