1. Understanding Earthquakes: History of Seismology to 1910: Page 1 of 3
- www.crustal.ucsb.edu
- Would you believe that giant snakes, turtles, catfish, or spiders live underneath the ground, and it is their movements that create earthquakes? Maybe you wouldn't, but your ancestors did. Ancient peoples had many fanciful explanations for earthquakes, usually involving something large and restless living beneath the earth's surface. ...
- Aristotle was one of the first to attempt an explanation of earthquakes based on natural phenomena. ...
- Empirical observations of the effects of earthquakes were rare, however, until 1750, when England was uncharacteristically rocked by a series of five strong earthquakes. These earthquakes were followed on Sunday, November 1, 1755, by a cataclysmic shock and tsunami that killed an estimated 70,000 people, leveling the city of Lisbon, Portugal, while many of its residents were in church. This event marks the beginning of the modern era of seismology, prompting numerous studies into the effects, locations, and timing of earthquakes. ...
- Prior to the Lisbon earthquake, scholars had looked almost exclusively to Aristotle, Pliny, and other ancient classical sources for explanations of earthquakes. ... Cataloging of the times and locations of earthquakes and studying the physical effects of earthquakes began in earnest, led by such people as John Michell in England and Elie Bertrand in Switzerland. ...
- These efforts were often spurred on by earthquake catastrophes, such as the 1783 Calabrian earthquakes that killed 35,000 people in the southern toe of Italy. ...
2. Earthquakes in Hawai`i
- wwwhvo.wr.usgs.gov
- Earthquakes in Hawai`i are closely linked to volcanism. ... Thousands of earthquakes occur every year beneath the Island of Hawai`i.
- Eruptions and magma movement within the presently active volcanoes (Kilauea, Mauna Loa and Lo`ihi) are usually accompanied by numerous small earthquakes. ... These are loosely termed volcanic earthquakes.
- Many other earthquakes, including the largest ones, occur in areas of structural weakness at the base of Hawai`i's volcanoes or deep within the Earth's crust beneath the island. These are referred to as tectonic earthquakes. In the past 150 years, several strong tectonic earthquakes (magnitude 6 to 8) caused extensive damage to roads, buildings, and homes, triggered local tsunami, and resulted in loss of life. ...
- Along with other signs of volcanic activity, we monitor earthquakes and seismic activity on Hawai`i continuously and in real-time to provide warnings of impending eruption and to assess seismic hazards in the State of Hawai`i. ...
- Map of current earthquakes.
- This map of Hawai`i shows the location and size of earthquakes that have occurred in the past two weeks. ... Felt earthquakes.
- This presentation introduces the differences between magnitude and intensity scales and provides links to a list of current felt Big Island earthquakes and a form for reporting felt earthquakes. Most earthquakes detected by our seismographic instrumentation are too small to be felt. Destructive earthquakes.
- Highlights Hawai`i's historical, destructive earthquakes, including large events on 2 April 1868 and 29 November 1975. ...
- A map of Hawai`i shows the location of earthquakes in the past 12 months. ...

- Would you believe that giant snakes, turtles, catfish, or spiders live underneath the ground, and it is their movements that create earthquakes? Maybe you wouldn't, but your ancestors did. Ancient peoples had many fanciful explanations for earthquakes, usually involving something large and restless living beneath the earth's surface. ...
- Virtually all Hawaiian eruptions are preceded and accompanied by an increase in the number of shallow earthquakes. ...
- New Technology to Help Measurement and Study of Earthquakes.
- Well before instrumental recording of earthquakes began, people learned to classify earthquakes by the strength of the shaking involved. ...
- The first practical scale for measuring earthquakes was developed by geologist Charles Richter at the California Institute of Technology in the 1930s, and the scale that most scientists use today still bears his name. ...
- How do scientists measure earthquakes?.
- There are two ways in which scientists quantify the size of earthquakes: magnitude and intensity. ...
- Scientists have long been using seismometers to measure the shaking of earthquakes. ...
- How do scientists know where an earthquake has occurred? Often earthquakes occur in regions which are remote, and few eye witnesses are available to help pinpoint the location of the quake, so how do we know exactly where the quake originated, that is, locate the epicenter? This exercise will explore one method which is used to do just that. ...
- To determine the strength and location of earthquakes, seismograph is used which is equipped with sensors called seismometers that can detect ground motions causes by seismic waves from both near and distant earthquakes. ...
- How Earthquakes are measured.
- Vibrations produced by earthquakes are detected, recorded, and measured by instruments called seismographs. ...
- Obviously, being able to successfully and reliably predict the occurence of earthquakes around the world, especially powerful ones, would save innumerable lives and billions of dollars. Throughout history, people have attempted to predict earthquakes in their area by observing and cataloging everything from strange animal behavior to "earthquake weather". ...
