which a mountain above Salò lowered; in 1703, when it caused the fall of numerous houses and caused many victims; in 1810, an earthquake particularly hit Malcesine where it caused a clouding of the waters and the formation of a crack long and wide in the town square; in 1836, when the tremors caused some landslides in Mount Tomè, in the northernmost part of Monte Baldo, which in turn caused a strong eruption of water. In 1866 a rather long period of seismic agitation began in Baldo area, with earthquakes of varying intensity, tremors, shaking and other phenomena of lesser importance, which saw as the most important event the earthquake of 5 January 1892, which shook the entire Garda region with extraordinary violence, causing the fall of chimneys and walls. Other earthquakes more recently hit Salò and its surroundings, in particular the earthquake of 31 October 1901 caused widespread damage to buildings, some collapses and cracks in the ground, while another earthquake in 2004 caused damage to some buildings. Islands The lake has also numerous small islands and five main ones, the largest being Isola del Garda. Nearby to the south is San Biagio island, also known as the Isola dei Conigli ("Island of the Rabbits"). Both are offshore of San Felice del Benaco, on the lake's western side. The three other main islands are Isola dell'Olivo, Isola di Sogno, and Isola di Trimelone, all farther north near the eastern side. Climate The particularly mild climate favours the growth of some hardy Mediterranean plants, including the olive tree, parasol pine, mediterranean cypress, chinese windmill palm and Canary Island Date Palm. Some hardy citrus trees, such as hardy lemons and satsuma can also be found, which are extremely rare at this latitude (46° North). In ancient times, poets like Catullus wrote about "Lacus Benacus" with its mild climate vivified by the winds. The lake is oriented from north to south towards the Po Valley, so many winds typical of the lake are the result of a difference between lower and higher altitude temperatures. Due to this, winds are generated that descend from the mountains to the plains in the morning and go back to the mountains in the afternoon. The bottleneck formed by the lake basin affects the timing of the winds, many of which happen on a regular daily basis. The winds are all named, most in regional Italian dialect
