Depth (km) 48.56
Magnitude (Mc) 3.6
Location 47.8458N 123.0378W
31.9 km WNW of Poulsbo, WA
42.6 km SE of Port Angeles, WA

This earthquake was followed by smaller earthquake 7 hours later
(2:51PM PDT) at a similar depth. Both of these earthquakes
occurred in the subducting Juan de Fuca plate. The second earthquake
was 27 km north of the first one. Deep earthquakes on the east
side of the Olympic Peninsula are not uncommon.

This is an automated web page produced after a
significant earthquake to give essential information about the
earthquake and previous earthquake activity
in the region. This information will be updated as needed.
If you would like, you may fill out a form describing how
the earthquake affected you.
This information will be used to
produce an "intensity" map illustrating how shaking and damage
from the earthquake varied from place to place.

Detailed Information and Graphics about the Earthquake
Our data base of earthquake hypocenters contains information
from the 19th century to the present.
Included are:
- A map of the Pacific Northwest
showing the location of the earthquake (in red) plus prior earthquakes M > 3.5.
Shallow events are black. Events deeper than 35 km are green.
- A map showing a closer view
of the earthquake and prior historical earthquakes
with magnitude 3.5 or greater.
Shallow events are black. Events deeper than 35 km are green.
- A list of 10 big earthquakes
preceding the mainshock that are closest to it and have a
magnitude greater than 3.5. These are the most significant
historical earthquakes in the vicinity of the mainshock
(see the closer view map above).
- A map showing
the location of the earthquake relative to cities.
- A map showing
the location of the earthquake relative to the nearest
seismograph stations that recorded it.
- A detailed list of all earthquakes
(M > 1.0) that occurred in the vicinity of the special earthquake
in the previous two years. For the locations of these events see
the next map.
- A map of all earthquakes
(M > 1.0) that occurred in the two years prior to the special earthquake.
Detailed area shown is just few kilometers around the mainshock.
- A List of the nearest 20 strong motion sites
Earthquake Mechanism
If sufficient P-wave first motion data are available,
a fault plane determination for the earthquake
will be available in the form of
Moment Tensor Estimates of the Earthquake size may also be available. To see,
