His scale worked like a <a href="/wiki/Seismogram" title="Seismogram">seismogram</a>, measured by a particular type of <i>seismometer</i> at a distance of 100 kilometers (62 mi) from the earthquake. </p><p>Earthquakes 4.5 or higher on the Richter scale can be measured all over the <a href="/wiki/World" title="World">world</a>. An earthquake a size that scores 3.0 is ten times the amplitude of one that scores 2.0. The energy that is released increases by a factor of about 32. </p><p>Every increase of 1 on the Richter scale corresponds to an increase in amplitude by a factor of 10 so therefore, it is a logarithmic scale. </p> <table width="600" class="wikitable mw-collapsible mw-collapsed pretty" border="2"> <caption>Richter Scale Magnitude </caption> <tbody><tr> <th>Descriptor </th> <th>Richter Magnitude number </th> <th>Damage caused by the earthquake </th> <th>Frequency of occurrence </th></tr> <tr> <td>Micro</td> <td>Less than 2.0 </td> <td>Micro (very small) earthquakes, people cannot feel these. </td> <td>About 8,000 each day </td></tr> <tr> <td>Very minor</td> <td>2.0-2.9 </td> <td>People do not feel these, but seismographs are able to detect them. </td> <td>About 1,000 per day </td></tr> <tr> <td>Minor</td> <td>3.0-3.9 </td> <td>People often feel these, but they almost never cause damage. </td> <td>About 49,000 each year (About 134 per day) </td></tr> <tr> <td>Light</td> <td>4.0-4.9</td> <td> <p>Objects inside houses are disturbed, causing noise.
