Seismology at the University of Arizona
This site gives a bit of insight into the academic applications of
reflection seismology with its summaries of recent research at the university.
It also manages to give a quick overview of 3-dimensional seimic data.

The previous web site is an excellent location for understanding practical
applications of improving seismic data. The web site will explain the implementation
of bilinear time-frequency representations in the interpretation of seismic
reflections. The time-frequency representations presents the seismic reflection
in a clear pattern thus providing useful interpretations of the subsurface
seismology of continental margins

Earthquake at Alumn Rock
On May 21, 1996 at 1:50PM, the Rapid Earthquake Location Service in
Menlo Park and U.C. Berkeley Seismographic Stations, in Berkeley, California
registered an earthquake of magnitude 4.7. It struck the Calaveras Fault
10 miles east of San Jose, California at a depth of 7.8km. The earthquake
was produced by lateral strike slip movement. This seismic event is consistent
with the horizontal motion of other earthquakes on the Calaveras Fault
and fits in a pattern of several other earthquakes in this area.

Harvard seismic data base provides the user with quick daily information
on the latest world wide major earthquake events, along with detailed information
on the Southern California area. The system has several earthquake location
systems that compile a list of the latest events, with information such
as magnitude, depth, time,... These earthquake locations are plotted on
a global map that displays several options such as zooming on location,

This is an extensive site on earthquake seismology. It has tons of
waveform data. The downside is that it's all in X-window format. But, hey!!
We can handle that, right? Although it only covers north European activities,
it seems very educational. All the waveform data is in compressed GSE1.0
format. The page also includes a very interesting post of all recorded
earthquake activity from 1375 AD to present.
Ocean Seismic Network
Gian Constantine 10/1/96
The goal of the Ocean Seismic Network (OSN) Pilot Experiment is to
deploy for a three-month period an observatory-grade seismometer in a case
borehole (OSN-1 aka ODP 834B, 225 km SSW of Oahu) and to simultaneously
compare the data with broadband instruments lined up at and directly beneath
the sea floor. One of the objectives of the experiment will be data collection
which will assist in determining the structure of the Hawaiian swell. The
project results may help answer questions about the Hawaiian upper mantle,
plume and lithosphere structure.
Southern Ontario Seismic Network

The Southern Ontario Seismic Network provides information about the
seismic hazards in Southern Ontario since 1991. Six seismic stations are
operated by the University of Western Ontario for Ontario Hydro (this company
owns nuclear power plants in that area).
This web site provides a seismicity map of Southern Ontario as well
as a list of recent earthquakes, including location, magnitude, waveform
plots. A list of major teleseismic events recorded by the SOSN (nuclear
tests for example) and a list of recent Canadian events can also be found.

UCLA Southern California seismicity homepage allows access to a wide
range of information based upon earthquakes in the Los Angeles Basin. Individual
earthquakes are shown on detailed maps with their magnitude, location and
type of faulting recorded. In addition, photographs of the damage caused
during individual events are shown. Particular attention is focus on the
Northridge earthquake with an impressive 3D animation displaying epicenter,
fault location and topography.
University of Nevada
David Hinds 9/30/96
This site, run by the University of Nevada, Reno, includes a wide variety
of information on earthquakes both local and worldwide, and offers links
to earthquake related pages. In addition, there is access to earthquake
archives and catalogs, as well as information about the Nevada Seismological
Laboratory and its staff.
The "Earthquake Information Page" within the site features listings
of recent earthquakes, press releases for major earthquakes, fault maps,
and locator maps for both local and global events. A unique feature for
people who have been through an earthquake is an on-line form that they
can fill out with descriptions of their experience. Another interesting
item is an up-to-the-minute live picture of an analog earthquake drum seismogram
showing current seismic activity.

This URL is the right place for you to update your knowledge about
earthquakes and seismology in general and also to be a part of an endeavor
to take action in developing ways to prevent many hazardous occurrences
related to earthquakes. This site is a real source of answers for many
public questions about earth sciences. Among many other topics, you can

"Surfing the Internet for Earthquake Data" by Steve Malone provides
internet connections where original seismic data or seismic research information
is available. The information presented is easy to read and very pertinent
to earthquake seismology. "Special News Items" regarding the annual conferences
and AGU meetings is also available. Sites for "Physics of Earthquakes",
"Seismic Hazard Mapping", "Deep Earthquakes and Physical and Geochemical
Processing" and "Active Hawaiian Volcanoes" are also offered. Detailed
attention is given to each topic. Global or Composite earthquake catalogs,
maps and data providing at least 200 links are also accessible from this
