<abstract>
<p>On 20 February 2010, an extreme rainfall episode occurred on Madeira Island,
which caused an exceptionally strong flash flood and several soil slip-debris
flows, producing 45 confirmed deaths and 6 persons declared missing, as well
as extensive material damages. In order to understand and quantify the
importance of landsliding in routing sediment through mountainous drainage,
such as Madeira Island&apos;s landscape, it was essential to perform extensive
landslide analysis. This study describes the methodology used to
semi-automatically detect the landslides, produce the landslide inventory
maps and estimate the sediment volume produced during this particular event
which ranged from 217 000 m&lt;sup&gt;3&lt;/sup&gt; to 344 000 m&lt;sup&gt;3&lt;/sup&gt; and 605 000 m&lt;sup&gt;3&lt;/sup&gt; to
984 000 m&lt;sup&gt;3&lt;/sup&gt; for the Funchal and Ribeira Brava basins, respectively. These
results contributed to the design and implementation of measures to prevent
damages caused by landslides in Madeira Island.</p>
