EARTHQUAKE HAZARDS PROGRAM

The USGS monitors and reports on earthquakes, assesses earthquake impacts and
hazards, and conducts targeted research on the causes and effects of
earthquakes. We undertake these activities as part of the larger National
Earthquake Hazards Reduction Program (NEHRP), a four-agency partnership
established by Congress.

PERFORMANCE-BASED EARTHQUAKE EARLY WARNING FOR TALL BUILDINGS

The ShakeAlert Earthquake Early Warning (EEW) system aims to issue an advance
warning to residents on the West Coast of the United States seconds before the
ground shaking arrives, if the expected ground shaking exceeds a certain
threshold. However, residents in tall buildings may experience much greater
motion due to the dynamic response of the buildings. Therefore, there is an
ongoing effort to

SUMMARY OF CREEPMETER DATA FROM 1980 TO 2020—MEASUREMENTS SPANNING THE HAYWARD,
CALAVERAS, AND SAN ANDREAS FAULTS IN NORTHERN AND CENTRAL CALIFORNIA

This report is an update to the presentation by Schulz (1989) introducing
potential users to the creepmeter data collected between the publication of
Schulz’s report and mid-2020. The creepmeter network monitors aseismic, surface
slip at various locations on the Hayward, Calaveras, and San Andreas Faults in
northern and central California. There are different designs of creepmeters and
these are b

DISTINCT YET ADJACENT EARTHQUAKE SEQUENCES NEAR THE MENDOCINO TRIPLE JUNCTION:
20 DECEMBER 2021 MW 6.1 AND 6.0 PETROLIA, AND 20 DECEMBER 2022 MW 6.4 FERNDALE

Two earthquake sequences occurred a year apart at the Mendocino Triple Junction
in northern California: first the 20 December 2021 �w 6.1 and 6.0 Petrolia
sequence, then the 20 December 2022 �w 6.4 Ferndale sequence. To delineate
active faults and understand the relationship between these sequences, we
applied an automated deep‐learning workflow to create enhanced and relocated
earthquake catalogs
