Where can I find the USGS earthquake data?
The data obtained from active source studies are archived at IRIS and/or at the National Geophysical Data Center. USGS also provides access to certain data sets. Non-USGS sites that host various geophysical, geodetic, and geologic data pertinent to earthquake studies:
Where does the USGS use GPS to measure crustal deformation?
The USGS uses GPS to measure crustal deformation all over the United States. However most of the work is concentrated in the western states where most earthquakes occur and where rates of crustal deformation are high.
How to transform GPS coordinates to Pseudo Mercator?
I’ve created a couple of functions using the math package from python 3.5 to transform GPS coordinates to x/y web mercator (pseudo mercator) as explained here: http://wiki.openstreetmap.org/wiki/Mercator#Java
What kind of JSON does The GeoJSON feed use?
GeoJSON uses the JSON standard . The GeoJSONP feed uses the same JSON response, but the GeoJSONP response is wrapped inside the function call, eqfeed_callback. See the GeoJSON site for more information. This feed adheres to the USGS Earthquakes Feed Life Cycle Policy .
How are students using seismic data to locate earthquakes?
In this activity, students use recent 3-component seismograms (recordings of motion on the N/S, E/W, and up/down axis) to locate quakes. Students identify P and S waves in their seismograms and measure the time between arrival of the P and S wave.
How is the power law used in earthquake forecasting?
The power law model is widely used for building earthquake hazard maps [6], which estimate the probability of exceeding a given magnitude over a specified amount of time, usually tens or hundreds of years. Thus, it is usually applied to long-term earthquake forecasting (like in [7]).
How can we find the source of an earthquake?
A tremendous number of earthquakes occur every year around the world. The primary tool seismologists use to locate the source of each quake is a network of seismometers. Seismometers are instruments designed to be sensitive enough to feel even the smallest motion of the waves coming from distant locations on Earth.
