Two additional earthquakes, magnitudes 6.6 and 6.7 occurred the next morning. The first earthquake was located six miles north of Petrolia, California, in a sparsely populated part of southwestern Humboldt County. Five small communities were located within a 50 mile radius of these events: Honeydew, Petrolia, Rio Dell, Scotia, and Ferndale. This slide set illustrates the effects and damage of a moderately large earthquake and moderate aftershocks on this sparsely settled area.Statistics - The first earthquake was located six miles The main earthquake came immediately after a Saturday morning parade at Ferndale. Horses reportedly became spooked during the parade (before the earthquake), but riders attributed it to flags fluttering in the wind along the parade route.Seismicity and Geology - The Cape Mendocino region of California's north coast is one of the most seismically active regions in the conterminous United States. This seismic zone coincides with the Mendocino Triple Junction, a tectonically unstable area where three tectonic plates join together.The earthquake of April 25 is exceptional for several reasons. It generated a tsunami that was recorded along the West Coast and measurable in the Hawaiian Islands. It also produced distinct uplift (maximum uplift = 1 m) along a 25-km-long section of the coastline. The April 25 event was the largest historic earthquake in this region with an epicenter clearly located on land, and the only damaging event that may have resulted from thrust faulting along the Cascadia subduction zone.Earth Effects - A broad zone of ground fractures, coastal uplift, and elevation changes are the only surface changes to indicate the location and tilt of the fault plane. Strong ground shaking during the earthquakes triggered numerous landslides in steep mountainous areas. A landslide at Scotia Bluffs (south of Scotia) temporarily interrupted traffic on the North Coast Railroad. Tension cracks, due to soil compaction and downhill slumping, restricted traffic on the Mattole Road between Honeydew, Petrolia, and Ferndale. Liquefaction took place in modern deposits of the Mattole River between Petrolia and Honeydew, and in the flood-plain deposits of the Eel and Salt Rivers. Soils liquefy when ground water near the surface is forced between the grains of sand during an earthquake. The sandy soil behaves like a very thick liquid. Structures then settle or tip in the liquefied soil, or are ripped apart as the ground spreads laterally or flows. Sand blows result from the eruption of liquefied sediment from the subsurface on to the ground. The eruption of liquefied sediment is facilitated by fissures in the ground, which are also produced by strong shaking during an earthquake.Damage - Collectively, these shocks caused significant damage to older structures in the sparsely populated, mountainous, epicentral region. The earthquake caused 98 injuries and moderate damage in Humboldt County. Losses topped $66 million. Single- and double-story, wood-frame houses and commercial buildings were the most common type of structures in the epicentral region, where lumber is the principal industry. Many foundations were the pier and post type, providing little resistance to lateral ground shaking. The earthquakes jarred many older homes off their foundations. purpose: Make available Damage Photos for research and education credit: Patricia Lockridge status: (MD_ProgressCode) completed pointOfContact: (CI_ResponsibleParty) individualName: Heather McCullough organisationName: DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce contactInfo: (CI_Contact) phone: (CI_Telephone) voice: (303) 497-3707 facsimile: (303) 497-6513 address: (CI_Address) deliveryPoint: NOAA/NESDIS/NGDC E/GC3 325 Broadway city: Boulder administrativeArea: CO postalCode: 80305-3328 country: USA electronicMailAddress: Heather.McCullough@noaa.gov hoursOfService: 7:30 - 5:00 Mountain contactInstructions: Contact Data Center role: (CI_RoleCode) pointOfContact resourceMaintenance: (MD_MaintenanceInformation) maintenanceAndUpdateFrequency: (MD_MaintenanceFrequencyCode) notPlanned graphicOverview: (MD_BrowseGraphic) fileName: http://www.ngdc.noaa.gov/hazard/icons/small_res/16/16_338.jpg fileDescription: This yellow Victorian house in Ferndale shifted, causing the brick chimney to break into two parts.
