  <dc:description>&lt;p&gt;&lt;span&gt;Geologic and radiometric-age data indicate that El Chich&amp;oacute;n was frequently and violently active during the Holocene, including eruptive episodes about 600, 1250, and 1700 years ago and several undated, older eruptions. These episodes, involving explosive eruptions of sulfur-rich magma and associated dome-growth processes, were apparently separated by intervals of approximately 350 to 650 years. Some of El Chich&amp;oacute;n's eruptions may correlate with unusual atmospheric phenomena around A.D. 1300 and possibly A.D. 623.&lt;/span&gt;&lt;/p&gt;</dc:description>
