Good morning, 

I'd like to request information about the seiche hazard or landslide induced earthquakes that have taken place or may take place in the future in Laguna Lake. This is for the Hazard study for MRT L4 project along Ortigas avenue, between Quezon City in NCR and Taytay in Rizal. We need to know if there is any documented seiche risk that could affect the alignment. 

Any information or reference to available research will be useful and appreciated.
