EQ Waves. Earthquakes shake the ground because fault rupture releases vibrations that radiate in the form of seismic energy. These earthquake waves, also called body waves, come in two distinct forms: Primary or "P" waves and Secondary or "S" waves. When body waves reach the free surface of the earth some of their energy is converted into ...Thunderbirds are usually said to bring storms and rain in the native stories. They create thunder by flapping their wings and shoot lightning bolts out of their eyes. To the Pacific Northwest Indian, the Thunderbird is the most powerful of all spirits. The thunderbird is a regular fixture on top of totem poles of native tribes in the Northwest. 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 ... Volcano Hazard Maps. Volcanos present a variety of hazards that should be considered when assessing risk. Cascade Volcanos can produce lahars (or debris flows mixed with water), pyroclastic flows of hot gasses and rocks, and ash fall that can range from a light dusting near the volcano to very heavy deposits that can bury soils and (rarely ...

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 an organization that provides information about earthquakes and ground motions in Washington and Oregon.

When magma is injected or removed from the system, surrounding rock will either shift to make room for the injected magma, or fill in a vacated area. These actions are the cause of volcanic earthquakes. The PNSN is …

Sep 14, 2023 · Last update was December 14, 2017. 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). 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, …
