Any change in the lake&#x27;s depth will affect the river, he added. </p><div class="embed-wrap"><figure data-feedback="fb:likes,fb:comments"><img src="http://sa.kapamilya.com/absnews/abscbnnews/media/2020/news/01/16/taal2.jpg"/><figcaption>A man is seen at the Pansipit river, which is drying up, in Taal town in Batangas on Jan. 15, 2020.<em> George Calvelo, ABS-CBN News</em></figcaption></figure></div><p>The lake&#x27;s level could have also dropped due to &quot;ground deformations&quot; caused by the quakes spawned by the volcano, said Solidum. </p><p>&quot;Posible kasi na bumabagsak ang ibang parte ng lawa at iyong ibang parte naman ay umaangat,&quot; he said. </p><p>(It&#x27;s possible that some parts of the lake is dropping and other parts are rising.) </p><div class="embed-wrap"><figure data-feedback="fb:likes,fb:comments"><img src="http://sa.kapamilya.com/absnews/abscbnnews/media/2020/news/01/16/taal1.jpg"/><figcaption>Fishermen make their way back to the shore after checking upon their fish farms in Taal lake, Talisay town, Batangas on Jan. 13, 2020.<em> George Calvelo, ABS-CBN News</em></figcaption></figure></div><p>Huge cracks, he noted, recently opened in Lemery, Agoncillo and Talisay towns due to the quakes, which are likely caused by magma rising towards the volcano&#x27;s crater. </p><p>In the past 24 hours, Phivolcs recorded 494 quakes triggered by Taal, of which 14 were felt, the strongest at a &quot;weak&quot; magnitude 3, said Solidum. </p><p>Taal also continued bleching an 800-meter ash plume and about 4,100 tons of sulfur dioxide per day, he said. </p><p>The volcano remains under the second highest danger level, which means a &quot;hazardous explosive eruption is possible within hours to days,&quot; said Phivolcs. </p>
