1. The red circle is the approximate area in Kalatungan and Kitanglad ranges where heavy Sendong rains fell. It is also the approximate area where logging is rampant e.g. Vicmar Dev’t Corporation and Bualan Cooperative which was exempted by DENR in April from EO23 or the PNoy logban.
2. The two red lines to CDO and Iligan is the water flow from the denuded forests.
3. This would show the source of the flood waters that hit simultaneously Cagayan de Oro and Iligan, and sparing the coastal municipalities in between Iligan and Cagayan de Oro. Heavy rains brought by typhoon Sendong fell in the Kalatungan range. If you observe the light green-brownish color, it indicates thin vegetation. This is where massive logging is happening for the last 30 years. If you notice it drains straight to CDO. If you go to the left of the map, down Kalatungan is Kapai and Mandulog, this is the part that drains to Iligan. There are ridges and gorges there that feed directly to the Mandulog river.
I’m sending my little help with these odious facts in mind…
