Signs of 1906 Earthquake in Offshore Map of Northern San Andreas

“A new high-resolution map of a poorly known section of the northern San Andreas Fault reveals signs of the 1906 San Francisco earthquake, and may hold some clues as to how the fault could rupture in the future, according to a new study published in the Bulletin of the Seismological Society of America.”

Tsunami Record from the Great 1906 San Francisco Earthquake

Shortly after the Great San Francisco earthquake of April 18, 1906, a sea level disturbance (tsunami) was recorded at the Presidio tide gauge station in San Francisco (the station is now located nearby at Ft. Point). What type of mechanism (earthquake rupture, landslide, other) generated the tsunami recorded at the Presidio tide gauge station?
