Hello! Thank you for sharing. My country, Denmark, experiences far fewer landslides. So much so that it was hard for me to find information on it. It is devastating to hear at the costly affects landslides have on Papua New Guinea. It really makes me stop and appreciate how lucky I am that I have never had to experience a landslide.
