Where can you get immediate online information on earthquakes?
NEIC – the National Earthquake Information Center.
What is USGS ShakeMap?
ShakeMap (http://earthquake.usgs.gov/shakemap)—rapidly, automatically generated shaking and intensity maps—combines instrumental measurements of shaking with information about local geology and earthquake location and magnitude to estimate shaking variations throughout a geographic area.
Where was the 6.2 earthquake today?
A 6.2 magnitude earthquake struck offshore in the Cape Mendocino area of Northern California, followed by aftershocks that rattled nerves and caused items to fall from shelves, authorities said Monday. No major damage or injures were reported.
Does USGS have an app?
The USGS “Water On-the-Go” mobile-friendly website/app | U.S. Geological Survey.
Is there a USGS app?
The National Map topographic maps and data of USGS are now available on both Android and iOS mobile devices.
What is the difference between earthquake intensity and magnitude?
Magnitude is a measure of earthquake size and remains unchanged with distance from the earthquake. Intensity, however, describes the degree of shaking caused by an earthquake at a given place and decreases with distance from the earthquake epicentre.
What is a green pager?
The estimated losses trigger the appropriate color-coded alert, which determines the suggested levels of response: no response needed (green), local/regional (yellow), national (orange), or international (red).
Was there an earthquake in South Africa today?

How does USGS collect earthquake data?
– Context. This exercise is part of an introductory geology course. – Goals. Students will consolidate concepts related to earthquake epicenters, foci, and magnitudes and explore subduction-related earthquakes and the geometry of a Benioff zone. – Description of the activity/assignment. – Determining whether students have met the goals. – Other Materials
What does USGS stand for in earthquake?
– the total variability that comes from the uncertainty in shaking hazard for each earthquake – the uncertainty in the population exposure – possible errors in the number of recorded deaths in the catalog for these events
What is the purpose of USGS earthquake?
