Station Monitor

Did the ground move near me?

Use your device’s location to find stations near you. When prompted, please ‘allow’ location access.

Find stations in the vicinity of a zip code or input a station name and select it from the list.

Find the station on the interactive map.

No data available!

A station may be down for selected date.

Try selecting a different date or a close by station.

Stations are largely autonomous and not always within arms reach of a technician.

Data might not be available for a selected channel.

Try selecting a different channel from the Advanced Feature section.

Sometimes, station metadata is not updated by the station operator and this could lead to data not being available on some channel.

The Station Monitor is designed to provide a quick look at data from seismographs around the world, but it is not designed for research purposes, as it does not provide access to all of the data stored at the EarthScope Data Management Center. To access the complete holdings for a particular earthquake, please see Wilber 3

Advanced Features

Events
This will relax distance and magnitude filters and also reduce the signal to noise ratio threshold for an event to be listed. As a result, the list will show more potential events recorded by selected station. Some events listed will not be visible on the chart.
Channel
Channel selection will persist during a session in Webicorder and Event view. You can hover over the station name in the title and get the tooltip of channel. Channel selection is remembered during the session for each individual station.
Filtering
Filtering seismic station data makes it possible to enhance the visibility of earthquakes that might otherwise be obscured by seismic signals in other frequency bands. The options are to:
- enhance distant earthquakes by looking only at lower frequencies (below 1 Hz)
- enhance local earthquakes by looking only at higher frequencies (above 1 Hz)

About Station Monitor

Station Monitor provides access to continuous, real-time ground motion from hundreds of locations around the globe. This data, collected by seismometers, measure motion generated by earthquakes, volcanic eruptions, and other seismic sources. By viewing the recordings from multiple stations, you can explore how ground motion changes at various locations relative to the earthquake. Lots of other things can cause the ground to move besides earthquakes.

By regularly monitoring one or more stations maybe will learn how to detect these non-earthquake sources! To get started, view this this video.

Why can’t I see my station?

The Station Monitor lists only stations that are part of _REALTIME virtual network and when station metadata, maintained by the station operator, indicate data availability on BH?, SH?, HH?, EH?, EN?, HN?, LH? and VH? channels for the selected time period. Stations in the _REALTIME network are added/removed daily based upon station information and data availability.

Why can’t I see data from my selected station?

The Station Monitor is designed to provide a quick look at data from seismographs around the world, but it is not designed for research purposes, as it does not provide access to all of the data stored at the EarthScope Data Management Center. For example, data might not be available for the automatically selected channel on the selected day. To access the complete holdings for a particular earthquake, please see Wilber 3

Webicorder

Webicorder Station information: Station location, Town (US), State (US), Country, 3-4 letter station name - 2 letter seismic network name. Example: Marconi Conference Center, Marshall, CA, USA MCCM-BK
nM/S - Nanometers/second - Seismometers typically record how fast the ground is moving.
mM/S**2 - Millimeters/second squared - Some seismometers record acceleration of the ground.
A nanometer is 0.0000001 of a millimeter, or the scale of molecules. A millimeter is about the thickness of a dime. Note that some of the scales are written in exponential notation, where 1.5E5 nM/S means 1.5 X10X10X10X10X10 or 150000 nm or 0.15 mm/S.
Amplitude Scaling
Auto - Plot is scaled to largest signal of the day
Custom - Plot is scaled to optimal setting for that station
Fixed - Plot is scaled to a fixed value that is the same for all stations and is optimized for large earthquakes.

Event

P - Estimated arrival time of the Primary wave, the fastest wave traveling through Earth. The particle motion in the wave is in the direction of travel of the wave and the wave is similar to a sound wave.
S - Estimated arrival time of the Secondary or Shear wave. This wave travels more slowly than the P wave and the particle motion in the wave is side to side. S waves do not travel through liquids.
Surface Waves - These waves travel as a group around the surface of the earth and are usually the largest waves seen on the seismogram. The further away the earthquake, the more spread out the surface waves are in time.
