Researchers from the University of Michigan and the Scripps Oceanography Institute in San Diego have teamed up to form the project.
DETROIT (AP) – Michigan seismologists examine a meteor that exploded in January in the atmosphere over the state with the help of scientists at the Scripps Institution for Oceanography in San Diego
The seismologists of the University of Michigan and the California scientists are publish their combined data on Michigan's celestial events in a research paper. The findings could help researchers understand how often Boliden, the name for meteors that explode in the atmosphere, occurs outside the eyes of witnesses.

Witnesses watched the spectacular meteor flicker across southern Michigan sky. People in Illinois, Indiana, Pennsylvania, Ohio, Missouri and Ontario, Canada also reported seeing the meteor.
It is rare for such large meteor occurrences to occur in a densely populated area within the capacity of several scientific instruments  "This event fell into our lap and we studied something else," said Michael Hedlin, head of the Laboratory for atmospheric acoustics at Scripps.
Hedlin's team studied atmospheric gravitational waves with the help of infrasonic sensors in the eastern and central US countries, which are constantly recording low-frequency sound. 19659003] When the Meteor spread its sonic boom, Hedlin knew he had a lot of infrasound data on it.
Seismologist Jeroen Ritsema from the Department of Earth and Environmental Sciences at the University of Michigan also did not expect to study the event. But he knew he could constantly review recorded seismic data from the region to find the meteor's outburst. Seismometers are sensitive and detect the smallest ground movements, said Ritsema. He was able to track the meteor's explosion record at seven seismometer stations in Michigan, Ohio and Ontario.
Hedlin contacted Ritsema to combine her separate disciplines into a research project.
"We could localize it (seismic) right where the infrasound placed it," Ritsema said.
The two research teams jointly confirmed the location of the car's launch over Michigan and the time of the explosion.
Buried in the collected data "I have more new knowledge about bolide meteorite events," said Hedlin.
"You probably have a lot of secrets that we have not found yet," he said. "I want to find out."
