Mount Rainier is one of the most seismically active volcanoes in the Washington and Oregon Cascades. In an … They are widespread, result in $1-2 billion in damages, and cause more than 25 fatalities each year. Landslides are frequently triggered by strong ground motions. They are an important secondary earthquake hazard. The term landslide includes a wide range of ground movement, such as rock falls, deep failure of slopes, and shallow debris flows.

Native American Serpent Spirit-Power Stories. The Seattle fault runs east-west and cuts across Puget Sound, through downtown Seattle, and across Lake Washington. Geologic evidence indicates that it ruptured in a major earthquake (estimated magnitude 7.3) around A.D. 900, causing 7 meters (~21 feet) of offset at the surface, generating a tsunami ... Earthquakes Overview. Earthquakes have inspired fear and awe since beings on Earth possessed the capacity to feel these emotions. Earlier mystical explanations for earthquakes have been replaced in our rational era by natural mechanistic explanations informed by observational science. Stresses in the rock that make the Earth are usually in a ... The Pacific Northwest Seismic Network (PNSN) is an organization dedicated to reducing impacts of earthquakes and volcanic eruptions in the states of Washington and Oregon by providing accurate and ...Surface rupture is an offset of the ground surface when fault rupture extends to the Earth's surface. Any structure built across the fault is at risk of being torn apart as the two sides of the fault slip past each other. Normal- and reverse- (collectively called dip-slip) faulting surface ruptures feature vertical offsets while strike-slip ... PNSN is the Tier-1 regional seismic network of the Advanced National Seismic System (ANSS) in Cascadia; responsible for reporting on seismicity within the US states of Oregon and Washington.

The two primary areas of research the PNSN and related researchers are involved in include; 1. A semi-automatic tremor detection and location process that uses continuous waveform data from the PNSN and cooperating networks and has a web interface called, Interactive Tremor Map; 2. Experimental algorithms applied to waveform data from special ... The frequency of these aftershocks decreases with time. Historically, deep earthquakes (>30km) are much less likely to be followed by aftershocks than shallow earthquakes. Foreshocks are no different than any other earthquake and can be recognized as “foreshocks” only after a “main shock” has taken place. 5. The Pacific Northwest Seismic Network (PNSN) and CVO monitor seismicity at Mount Baker via a small network of two stations located within 20 km (12 miles) of the summit, as well as the broader regional PNSN network. With so few nearby stations, it is likely that very small (M < 1.0) earthquakes are not routinely detected and located at …Outreach Overview. One of the ways PNSN carries out its mission to reduce harmful effects of earthquakes is to promote the scientific understanding of earthquake hazards and how to prepare for seismic events.

Tremor is the release of seismic noise from slow slip along the interface of the Juan de Fuca and North American plates and lasts for several weeks to months. This process is known as Episodic Tremor and Slip (ETS). Slow slip happens down-dip of the locked zone (Figure 2). Lahars. Lahars are mudflows that contain at least 60% volcanic material (ash and debris from previous eruptions included). They originate high on a volcanic edifice, have the density of wet concrete, and follow stream …

Spectrograms are a different way of presenting seismic waveform data for human review and interpretation. Similar to seismograms they show seismic energy versus time, but also include information about the frequency content of the seismic waves. For a complete description of spectrograms, with keys to their interpretation, …

Landslide Hazard Maps. Landslides tend to occur where past landslides have happened. Where records have been kept, landslide inventory maps provide a useful first level view of where the risk is highest. Slope angle, subsurface geology, and rainfall data added to this knowledge base can inform landslide predictions and mitigation priorities.
