That quake is estimated to have been a 6.25 shaker and was felt throughout New England. (2.2 miles), 1976-03-14 23:12:24 UTC An earthquake initiates with the sudden slip of rock on either side of a crack in the earth, called a fault. Enter your email address below to receive updates each time we publish new content. Most of the states in the Northeast have adopted some seismic provisions into the state or local building codes for certain types of new construction. In Newbury, MA and Hampton, NH liquefaction features called sand blows formed when the strong ground shaking ejected water and sand from the ground below, sometimes covering an area as large as 10 yards. In Boston, the damage was quite extensive. An earthquake is a combination of different phenomena. Epicenter at 41.69, -71.242 The North American plate is begin pushed away from the European plate and from the African plate at the Mid-Atlantic Ridge, which runs down the center of the Atlantic Ocean from near the North Pole to near Antarctica. 9.2 km from Earthquakes happen much more frequently in California than in the northeastern US, with the rate of earthquakes being about 100 times greater in California. So, what is the potential for a big one, a California-esque quake in staid New England? Epicenter at 41.33, -72.88 Epicenter at 41.334, -72.473 For example, a bookshelf over a bed is a bad idea because strong earthquake shaking can hurl books off the shelf and onto the person in the bed below. The areas of filled land would be expected to experience stronger ground shaking and the potential for damage. (0.2 miles), 1996-03-22 20:22:12 UTC Based on the history of large earthquakes in the Northeast and the continued occurrence of smaller events scientists are able to estimate the average repeat times for earthquakes in the Northeast. The quake, which measured at a 1.9 magnitude, was measured in Weare about 3:19 a.m. Sunday. Sometimes smaller earthquakes, called foreshocks, occur in the hours or days before a large earthquake and at the same epicenter as the large earthquake. Dr. Charles Richter of Caltech devised the first earthquake magnitude scale, which is called the Richter scale. Some earthquake hazard mitigation measures are geared toward reducing the chances that buildings and other structures will be damaged by earthquakes. An underlying problem might be a weak foundation, damage due to rot or bugs, or improper design or modifications. -, The Northeast States Emergency Consortium (NESEC) is funded by the Department of Homeland Security/Federal Emergency Management Agency (FEMA) to provide FREE assistance to help local, state, regional and other organizations, Map Your Risk – FREE Multi-Hazard Risk Mapping Assistance, the Modified Mercalli Intensity (MMI) scale, State Building Codes and Structural Safety Provisions for URM Buildings in the Northeast States, What to do Before, During, and After an Earthquake, Federal Emergency Management Agency (FEMA), Connecticut Department of Emergency Management and Homeland Security, Massachusetts Emergency Management Agency, New Hampshire Homeland Security and Emergency Management, New Jersey Office of Emergency Management, New York State Office of Emergency Management. 2.2 km from This measure is called the earthquake intensity. 4.2 km from Biden COVID-19 Response Begins; McConnell Says Trump '100%' Right, Being Black in White Spaces with Author Julie Lythcott-Haims. Chatham Epicenter at 41.193, -71.658 Wood frame tends to be resistant to earthquake shaking without collapse unless there is some underlying problem. All rights reserved. The Cape Ann earthquake caused severe damage to the Boston waterfront. Soft soils, such as filled land and river sediments, tend to amplify some aspects of earthquake ground shaking compared to nearby sites that have bedrock or ledge at the surface. The next damaging earthquake might not occur for many years, or it might occur tomorrow. If unable to do so, the rule of thumb is to “duck, cover and hold”. (0.2 miles), 2015-01-08 14:27:59 UTC Modern analysis places its epicenter somewhere near central New Hampshire, and it probably measured between magnitude 6.5 and 7.0 on the Richter magnitude scale,[2] making it the largest earthquake on record in New Hampshire and one of the strongest in the region's history (the 1663 Charlevoix earthquake was probably stronger). For information, contact your local or state office of emergency management. Earthquakes in eastern North America occur because of the pressure that builds up within the middle of the North American tectonic plate. People in New England, and in its geological extension southward through Long Island, have felt small earthquakes and suffered damage from infrequent larger ones since colonial times. Volcano Discoveries: "One of the most eye-catching guides to the world’s volcanoes ever published. Earthquake warning systems are very complicated and must be designed and built separately for each area on the earth. In 1925, a 6.2 quake struck in Canada and was felt in New England, as well. Acushnet Center At between 6.0 and 6.3 on the Richter scale, it remains the largest earthquake in the history of Massachusetts. There are thousands of old geologic faults throughout the entire northeast, and so far seismologists have not accumulated enough earthquake data to show which of these faults may be active today. In fact, major earthquakes — reaching magnitudes as high as 6.5 — have inflicted widespread damage in the New England before. If a gas leak is noticed, light switches cannot be used and matches should not lit until the gas line is turned off and the gas in the air has dissipated. (1.2 miles), 1976-05-10 01:34:20 UTC Undersea earthquakes can also pose a tsunami hazard. There is an operational early warning system throughout Japan, and Mexico City has an early warning system for strong earthquakes along its Pacific Coast. Connect with friends faster than ever with the new Facebook app. Nevertheless, the science of seismology seeks to understand what causes earthquakes by tracking their occurrence, measuring their force and using sophisticated imaging technology to probe the subsurface geology where they happen. An earthquake can cause damaging ground shaking when its magnitude is above about magnitude 5.0. They can occur at any time without warning. restricting visitors due to coronavirus concerns, New Hampshire couple stranded in China due to coronavirus concerns, DA: Man killed by police after hospital shooting, violent crash shot 26 times, READ THE FULL STORY:3 earthquakes recorded in New England, off coast since Sunday. The earthquake was centered a few miles off of New Bedford and was felt in Massachusetts, Rhode Island, Connecticut, New Hampshire and Long Island. For example, soft soil that is 30 feet thick might amplify the aspect of the ground shaking that is most damaging to 1-2 story buildings. Your first line of protection against earthquakes is the strength of your home. A seismic hazard curve is a plot of probability versus level of ground shaking that the site might experience during some time period (such as 50 years). Scientists often create maps of urban areas that show where ground shaking amplification is most likely to take place, with each map showing the amplification factors that will affect buildings of different heights. Most of the major cities in the NESEC states have had one or more damaging earthquakes centered near them in historic times. Portsmouth #cliffwalk, Did you know that you can still watch sports at @t, A student at Pell Elementary School was sent home, It’s Buck-a-shuck raw bar Wednesday at @tavernon, Ok it’s on TONIGHT! He does not expect that people in Massachusetts would feel the aftershocks. Why Does the Earth Quake in New England provides an excellent overview of why we have earthquakes in the Northeast. Southern New England has had: (M1.5 or greater) 0 earthquakes in the past 24 hours 4 earthquakes in the past 365 days Deep River Center The last earthquake to hit New England was a 2.1 magnitude centered just off of Martha’s Vineyard on July 23, 2020 and this was the largest earthquake in New England … Largest Earthquake in New York Magnitude 5.8 Sep. 4, 1944, 11:38 p.m. local time This severe earthquake was felt from Canada south to Maryland and from Maine west to Indiana. Bliss Corner The list refers to current country boundaries rather than those at the date of the earthquake; Please note, multiple countries could have the same earthquake listed, such as the 1906 Ecuador–Colombia earthquake being listed for both Ecuador and Colombia. Emergency escape routes should be kept clear. at 15:29 June 17, 1982 UTC, Location: The latest earthquakes in Southern New England. at 07:09 August 14, 2014 UTC, Location: These buildings are at the greatest risk to sustaining substantial damage should a strong earthquake take place. It was felt as far away as Montreal and New York City. It is important to know how to turn off natural gas if there is a gas leak following an earthquake. Dr. John Ebel, a geophysics professor at Boston College and director of the Weston Observatory Boston College, said earthquakes start to cause damage when they reach a 5.0 magnitude. An even stronger earthquake rocked the region from Nova Scotia to South Carolina on November 18, 1755. East Haddam This was about a magnitude 5.6 shock that was centered in the area of Newburyport, MA. If indoors, it is usually safest to stay indoors and to get under a sturdy piece of furniture such as a table or desk. Chatham The USGS has characterized the Northeast US as a region of low to moderate earthquake hazard. 6:30PM City Council Meeting, 67 years ago today, September 12, 1953, US Senator, This error message is only visible to WordPress admins, Pornhub Traffic Shot Up As Much As 14% On Election Day, Trump refuses to accept election results and says it’s ‘far from over’ – here’s his full statement, Raimondo announces grants to help businesses make up for pandemic-related losses, Newport man indicted for first-degree felony child molestation, Kate Leonard Thanks Voters of Newport’s Third Ward, (Updated) Visitors From These States Must Quarantine When Traveling To Rhode Island, Raimondo Cracks Down with New Restrictions Including a Curfew, Napolitano, Leonard, Holder and McCalla Win Big in Newport City Council Races. Following a strong earthquake that causes significant damage there can be many other problems that must be managed. For additional information about building codes in the Northeast States please click on the NESEC Building Code Report Image below. at 14:27 January 08, 2015 UTC, Location: Today, seismologists report the strength of the earthquake source using the more accurate moment magnitude scale. 6.2 km from This point is called the earthquake hypocenter or earthquake focus. Dr. John Ebel of the Weston Observatory of Boston College rates this earthquake at moment magnitude 7.5, comparable to the largest of the earthquakes that took place in the New Madrid, Missouri seismic zone in 1811 and 1812. Earthquake hazard mitigation involves actions that are taken to reduce the potential losses due to future earthquakes. (3.2 miles), 1982-01-27 18:50:05 UTC 2.2 km from Epicenter at 41.84, -70.7 3.2 km from Wauregan Evidence of damage from the 1755 earthquake can still be seen today at the historic Weeks House in Greenland, New Hampshire. at 07:13 March 12, 2002 UTC, Location: 4.2 km from There were damaging earthquakes near New York, NY (magnitude 5.0 in 1884), Boston, MA (magnitude 5.6 in 1727 and magnitude 6.2 in 1755), Buffalo, NY (magnitude 5.6 in 1929), and Hartford, CT (magnitude 5.0 in 1791). 0.2 km from For renewal of existing construction, earthquake resistance should be added whenever possible. at 16:49 October 21, 1981 UTC, Location: The largest known New England earthquakes occurred in 1638 (magnitude 6.5) in Vermont or New Hampshire, and in 1755 (magnitude 5.8) offshore from Cape Ann northeast of Boston.
