The Tintina Falls fault line stretches for about 600 miles, stretching from northeastern British Columbia to Alaska. It was previously thought that the fault line last moved 40 million years ago, but a new study has shown signs of activity in its more recent past. According to the study, published in Geophysical Research Letters, new topographic information obtained from satellites, aircraft and drones has shown that in a section of the fault, which is about 80 miles long, layers of rocks between 2.6 million and 132 thousand years old have been found in the Earth’s layers that stretch between the fault line. According to the study, the fault line last ruptured more than 12,000 years ago, but it is still possible to have earthquakes. According to experts, this fault line is at least prone to an earthquake of magnitude 7.5, which could cause a major natural disaster.
According to Michigan Tech, earthquakes of magnitude 7 to 7.9 are considered severe and can cause widespread damage. Such earthquakes occur 10 to 15 times a year. If the magnitude is 8 or higher, it can cause devastation in the entire region, and such an earthquake occurs every year or every other year. This new study by scientists is another reminder that we are not completely safe from natural disasters, and new evidence of seismic activity in this region has increased concern among local officials and residents. Will the regions of Canada and Alaska be safe from earthquake disasters? This question has now become a major challenge for scientists.
