Seismograms: Illustrated Guide to Reading a Seismogram (USGS)- Incorporated Research Institutions for Seismology

iris.edu This USGS video provides a tutorial for anyone interested in interpreting the seismic records on public webicorder displays. Seismometers measure vibrations. More vibration… more wiggle. Some seismometers measure only up and down; some measure up-down, north-south, and east-west motion. 

Earthquake Reported in Massachusetts on Sunday Morning

nbcboston.com A magnitude 4.0 earthquake was reported in southeastern Massachusetts on Sunday morning. According to the U.S. Geological Survey, the quake was centered in Bliss Corner, a section of Dartmouth. NBC10 Boston viewers in Massachusetts and Rhode Island reported feeling tremors. More to come.

The seismic signal from Hurricane Zeta is clearly visible on seismic stations along the Gulf Coast. Why?

Hurricanes and typhoons can increase the amplitude of ocean waves which, in turn, drum on the ocean floor. These produce Rayleigh waves that can be recorded hundreds of miles from an oncoming hurricane.

When's your Birthquake?

Getting students excited about earthquakes when they live in seismically inactive regions can be challenging. This activity is designed to overcome this by using the earthquakes that occurred on a students birthday as a hook!

Your 'Birthquake' is the largest earthquake that occurred on your birthdate. Students can discover their Birthquake, and answer a number of fundamental questions using the IRIS Earthquake Browser.

- How often do earthquakes occur?
- What is the relationship, globally, between the size of earthquakes and their frequency?
- What is the magnitude scale and what information does it convey?

Take 2: Hazard vs. Risk- Incorporated Research Institutions for Seismology

iris.edu A seismic hazard is the probability that earthquake shaking of a certain intensity will occur in a given geographic area, within a given window of time.  From that, risks can be assessed and included in mitigation efforts. Let's compare them.

IRIS Earthquake Science

Hidden amidst the tumult of seismic data generated by earthquakes, explosions and other earth-shaking phenomena is a relatively quiet hum. A short period noise (3- to 20-s), referred to as microseismic noise, is due to ordinary ocean waves pounding the seafloor, generally near the shore, and is relatively well understood. The longer period part of Earth’s hum (50- to 300-s) is caused by gravity-driven waves called "infragravity waves” that couple with the seafloor, but the details of infragravity-driven hum generation are enigmatic.

This angular unconformity is pretty awesome!

Angular unconformity at San Lorenzo canyon, New Mexico, U.S.A.

This small isolated mesa shows a stunning example of angular unconformity. The tilted beds of sandstones and mudstones below are Miocene age (7-10 Ma) layers that were faulted and tilted in the Rio Grande rift, then exposed and eroded. The layers above are Pleistocene (roughly 0.5 Ma years old) gravels.
