Earthquake Monitoring

Posted by Sam Churchill on


Astrobiology reports a rumbling South American volcano has gone wireless: Computer scientists at Harvard University and seismologists at the University of New Hampshire and University of North Carolina are monitoring volcanos using a wireless array.

The sensors at the Ecuadorian peak should help researchers, officials, and local residents understand and plan for eruptions of Mount Tungarahua, one of Ecuador’s most active volcanoes in recent years.

The researchers installed the wireless network on Tungarahua and captured 54 hours of data during a recent trip to the 5,016-meter mountain. The wireless system could eventually replace the wired sensors now used on Tungarahua and many other volcanoes.

An interdisciplinary team of the University of Southampton, GlacsWeb, has deployed a network of wireless sensors inside a Norwegian glacier to record its behavior. The sensor probes, housed in ‘electronic pebbles,’ are buried 60 meters under the surface of the glacier. They transmit wirelessly their observations about temperature, pressure or ice movement to a base station located on the surface.

Mt Saint Helens (WikiPedia), in Washington State, has recently produced thousands of small tremors (seismometer), recorded at the Cascades Volcano Observatory.

A 6.0 earthquake struck Central California on Tuesday that was felt from San Francisco to the Los Angeles area. There were no immediate reports of injuries.

The quake, which struck at 10:15 a.m. PDT, had a preliminary magnitude of 6.0 and was centered 7 miles southeast of Parkfield, the town known as California’s earthquake capital, according to the U.S. Geological Survey.
