Dear Maria Ysabella Gonzalez,

Greetings!

Thank you for your request dated May 09, 2023 03:24:54 PM under Executive Order No. 2 (s. 2016) on Freedom of Information in the Executive Branch.

Your request

You asked for Geological map and landslide susceptibility map of Rizal.

Response to your request

While our aim is to provide information whenever possible, in this instance this Office does proactively disseminate landslide hazard map thru its webportal. Furthermore, the geological map of the Philippines are sold by 1:50,000 scale quadrangles by the MGB Central Office located in North Ave., Diliman, Quezon City. Lastly, sinkhole and landslide incidents per year in the Province of Rizal are not available in this Office.


Thank you.

Respectfully,
Regional Office 4A

Dear Ma'am/Sir,

Good afternoon! :) Thank you very much for your helpful response and advice regarding the above data! In regards to the landslide susceptibility maps disseminated through your webportal, which I greatly appreciate, I wish to raise the concern that they may not be accessed without signing in as shown in the screenshot attached to this reply.

I was able to acquire a link to the landslide susceptibility map of Rizal Province from a similar request by Mr. Donguines last October 4, 2022 (https://lgsd.mgb.gov.ph/portal/home/webmap/viewer.html?webmap=b8751e0845034baaa759d19396ad0c52.) but as mentioned, I am unfortunately unable to access this as well.

My apologies for the additional hassle and I would like to express my deep gratitude for your effort in making important information readily available for students such as myself. I hope to hear from you soon and that you have a great week ahead. :)

Sincerely,

Maria Ysabella Y. Gonzalez
