GRCC seismometer records last Friday’s Anchorage earthquake

December 3, 2018

At 8:29 a.m. this past Friday, November 30, a magnitude 7 earthquake sent Anchorage residents scurrying out of buildings and under desks. Six minutes later, GRCC’s seismometer picked up the primary waves that traveled from Alaska to Michigan at a speed of over 13,000 miles per hour. There are preliminary reports of damage in Alaska’s largest city and the surrounding communities. A Tsunami warning was issued and then canceled later in the day.

Calkins Science Center at GRCC hosts a seismometer (GRMI) that is part of the MIQuakes network, a group of high schools, community colleges and universities in Michigan that host seismometers designed to record earthquake activity both locally and worldwide. The stations are sponsored by IRIS – Incorporated Research Institutes in Seismology and MESTA – the Michigan Earth Science Teachers Association.

If you are interested in or other earthquakes recorded by the GRCC seismometer, you can find them on the MIQuakes website.

GRCC Science Talks to tackle the Sun, species conservation in new lecture series

August 24, 2018

A new series of presentations on a variety of scientific topics begins this academic year. This lecture series is called ‘GRCC Science Talks.’ These lectures are free and open to the public. There will also be light refreshments available. Here are the first two presentations that may be of interest to you and your students this fall 2018 semester:

Unlocking the Sun: Spectroscopy in the 1800s

  • Who: Dr. Lauren Woolsey
  • When: Monday, September 17, 2018, at 3:45 p.m.
  • Where: Calkins Science Center (CSC) Auditorium (Room 348)
  • Description: Have you ever wondered how we know what the Sun is made of, even though it is far too hot for humans to visit? The story of how we discovered the chemical makeup of our own star combines chemistry, physics, and astronomy in a tale of mystery, far-flung expeditions, and unexpected discoveries. After an overview of spectroscopy for general audiences, GRCC Assistant Professor, Dr. Lauren Woolsey will take us through the secrets of the Sun from this turning point in science history.

Species Conservation: How We Got Here and What Can Still Be Done

  • Who: Dr. Greg Forbes
  • When: Monday, November 5, 2018, at 3:45 p.m.
  • Where: Calkins Science Center (CSC) Auditorium (Room 348)
  • Description: An examination of the reasons that animal and plant species are endangered today, the current status of species worldwide, nationally and in Michigan as well as some possible strategies to save some of these species as well as humanity. Dr. Forbes is an evolutionary biologist and a certified wildlife biologist with research experience

We look forward to participating in these events with you and our students. Please email Tim Periard (timothyperiard@grcc.edu) with any questions.

GRCC seismometer picks up Alaska earthquake

January 24, 2018

GRCC’s seismic station (GRMI) in Calkins picked up the magnitude 7.9 earthquake in Alaska on Tuesday morning. The earthquake was located at a depth of 25 km below the sea floor, southeast of Kodiak Island in the Gulf of Alaska. A tsunamic warning was initiated for much of the west coasts of the U. S. and Canada but was cancelled a few hours later. The fault that generated the earthquake was not of the type that usually triggers a damaging tsunami. More information about the earthquake can be found on the U. S. Geological Survey’s website. The figures below show the dramatic trace of the earthquake on the GRMI record. The second image is the pulled record of the earthquake and clearly exhibits the P wave (a seismic body wave that moves through the Earth) and the L wave (a high amplitude wave that travels on the surface of the Earth). The waves arrived at the GRCC station about 7 and 23 minutes, respectively, after the earthquake in Alaska, a testament to the speed of seismic waves!

GRCC seismometer records deadly Mexico earthquake

September 8, 2017

It’s been a busy week for seismometers. This morning, at 12:49 a.m. Michigan time, GRCC’s seismic station (GRMI) recorded a magnitude 8.1 earthquake (see red arrow in image below) off the Pacific Coast of Mexico. See the United States Geological Survey’s shake map below for location of the main shock and shaking intensity. This was the largest earthquake ever recorded on our station. Preliminary reports are that there are casualties and building collapses in communities closer to the earthquake. Mexico City appears to have sustained little damage or injuries thanks to strong building codes (since the devastating 1985 earthquake) and an early warning system that gave residents about 40 seconds to move to a place of safety. See the New York Times article for updates on the impact and the USGS website for additional information about the earthquake and aftershocks.

GRCC seismometer records Idaho earthquake, North Korean explosion

September 5, 2017

This past weekend, the GRCC seismic station in Calkins, GRMI, recorded a flurry of events. Most prominent was a magnitude 5.3 earthquake in Soda Springs, Idaho, just before midnight on September 2. Small aftershocks and more events in Soda Springs were recorded in the following 24 hours. Another notable event is marked by the red arrow on the image below, this coincides well with the timing of an explosion in North Korea, recorded by seismometers around the world. For more information about this event and others, go to the USGS’s website.

A red arrow points out the moment an explosion in North Korea was recorded on GRCC's seismometer.

GRCC seismometer records Montana earthquake

July 21, 2017

On July 6, 2017 GRMI, the seismometer in the geology lab of Calkins, recorded a magnitude 5.8 earthquake near Helena in western Montana. Buried in the seismic trace of the larger earthquake were two aftershocks, one measuring 4.9 and the other 4.5 in magnitude. In the seismogram, we can see many aftershocks associated with the magnitude 5.8 earthquake. This swarm of earthquakes occurred as the result of strike-slip (horizontal) faulting along the Lewis and Clark line, a broad zone of faulting about 400 km in length, and up to 80 km wide that extends from Helena, Montana southwest into eastern Idaho. Other notable events from the Lewis and Clark line include the August 1959, magnitude 7.2 Hebgen Lake earthquake, the largest historic earthquake in this region. The Hebgen Lake earthquake triggered a massive landslide that resulted in more than 28 fatalities, mostly in campgrounds around the lake. Fortunately, this most recent quake caused only minor damage and no reported injuries. For more information about the earthquake visit the U.S. Geological Survey’s website.

Readings from GRCC's seismometer on July 6 show a lot of activity on the 40-minute mark.
