Each other for comfort fearing the floor could fall below them. [ screaming ] reporter this video posted on twitter shows the side of another building collapsing to the ground as onlookers screamed and cried in horror. Streets in some parts of central mexico were littered with rubble and debris. Thousands of Community Members joined rescue workers as they worked tirelessly to start the recovery process. Someone was found in the rubble alive as crews rushed to carry survivors away on gurneys to seek treatment. More people were pulled with more likely trapped. [ speaking spanish ] reporter the president of mexico Enrique Pena Nieto speaking on Mexican Television talking about the schools that collapsed and how they are working to find out if children were inside when it happened. Meanwhile, he says local and federal agencies including the military are responding to hard hit areas with building collapses. Latest reports show structures fell in more than 40 locations in the capital alone. On friday, september 8th, an 8. 1 quake struck more than 600 miles southeast of mexico city killing nearly 100 people. Now, it was considered one of the strongest quakes to ever hit mexico. That was 11 days ago. Now things are different. Today mexico city is marking the anniversary of the destructive 1985 quake that struck mexico cit 32 years ago to the day. 5,000 people were killed in that quake. Thank you. And President Trump tweeted his support to the victims of the earthquake saying, quote, god bless the people of mexico city. We are with and we will be there for you. Lets bring in ktvus tom vacar with more on what made this earthquake so destructive. Reporter well, this bad stuff thats happening down there and could continue. Todays mexico quake involved massive natural structures tectonic plates that float and move on the earths mantle like this. Mexico has socalled subduction faults where one plate literally slides under another releasing energy quickly. This is the kind of event that can sometimes produce tsunamis and todays case the energy was released in the worst kind of rock and soil. Mexico city has really pathologic soil conditions. They have they are built in a lakebed that amplifies the earthquake shaking by a factor of 100 or more. When you have those soils and the earthquake nearby its not surprising that were seeing a lot of damage. The september 2nd mexico quake was in a sensorfilled area 500 miles away which gave more than a minutes warning but today the epicenter was 31 miles underground and only 75 miles from mexico in an area where there are far fewer sensors. That was way to close to provide warning rendering mexicos earthquake Warning System essentially useless. The earthquake early Warning System uses the fact that you can determine that an earthquake is under way and send that information somewhere faster than the waves can get there. So it only works if you are at some distance away. Reporter though extreme Northern California near oregon also has these kinds of tsunamicreating faults, here in the bay area we have what are called socalled slip strike faults where the plates grind against each other, yet still releasing an enormous amount of energy that can do just as much damage. Thats the situation with the earthquakes. Some of those pictures down there watching the buildings collapse are something. I cant help it. Every time we see a story about an earthquake, you have to think, at some point, thats going to happen here. Reporter the important thing is, for most areas, our building codes are so much better. The Building Structures are so much better that were likely not to see that kind of a problem. We may see Something Like that in chinatown, in San Francisco, we may see it in some of the older communities that are outlying more than 100 years old that havent done a lot to strengthen buildings and stuff like that. But for the most part, california is so much better than the rest of most of the world that were in really good shape, which is why we dont kill as many people nearly in earthquakes especially even the smaller ones. What about that area in the Marina District that has some of that soft foundation with liquifaction, not as bad as mexico city but is it softer than other parts or neighborhoods of San Francisco . Especially in a big earthquake which we havent experienced here in more than 100 years, you bet. The city is now seriously beginning to enforce what they call the soft bottom situation where you have a garage and then you have building on top and we saw a lot of those collapse in the ma marina. They either fix it or they may close down the buildings. Its different here in mexico where people ignore it. Thank you. Pictures, videos and words of support have been pouring in now on social media after todays deadly earthquake. These are just a few of the ones we have seen. Many are using the hashtags, mexico and earthquake. And stay with ktvu for continuing coverage. At 6 30, well bring you an update on the death toll and the rescue and Recovery Efforts under way right now in mexico.

There is strong reaction tonight from around the world to President Trumps fire ee speech at the United Nations today. In front of the General Assembly, President Trump said we would totally destroy north korea if we are threatened and said the Iran Nuclear Deal was an embarrassment to the United States. Many World Leaders are accustomed to a diplomatic tone took them aback. Ellison barber reports. Reporter some like Prime MinisterBenjamin Netanyahu from israel praised the speech saying it was bold and courageous but then you had others like leaders from venezuela also the french president Emmanuel Macron pushing back on certain aspects of it. One thing President Trump did not . Shy away from was north korea saying in the evented of war the country would be totally destroyed. I will defend americas interests above all else. Reporter President Trump delivering a speech of National Sovereignty before the United Nations. The success of the United Nations depends upon the independent strength of its members. Reporter he discussed Global Security and criticized nations that are reckless from iran a government President Trump said is a disguise for a corrupt dictatorship that funds terrorism to north korea who he referred to as rocket man. The United States has great strength and patience but if it istorsed to defend itself and allies well have no choice but to destroy north korea. Reporter the president s speech drawing strong reaction. Protests erupting outside trump tower over the president S Immigration policies as Global Leaders expressed mixed opinions to mr. Trumps performance. The Prime Minister of israel said reporter venezuelas foreign minister expressing disappointment. This is supposed to be the house and the headquarters of peace and the international law. And what we heard was the opposite of that. There were a few empty seats when President Trump went to the podium just before he started speaking. The representative from north korea left the room. Ellison barber in the Nations Capital tonight. Thank you, ellison. And joining us now onset is ktvu political analyst brian sobel. Thank you for being here. The president shook things up. Do you think his tough talk will make a difference or have an impact on north Koreas Kim Jongun . Well, the setting was such that the message was delivered clearly to north korea. This is a setting where you have people by and large diplomats live in new york. So they have been watching the Trump Administration and donald trump. So we as resident citizens of the United States we have seen a lot of this. But delivering that speech at that podium to the world was was trumpian. Do you think theres this theory, this mad man theory, that the president being so unpredictable, would strike fear in other World Leaders that they wouldnt want to set off the president . Is that something to take into consideration here . Reporter i think so because i i i think he is the type of of president , were learning, who is accustomed to the bluff, accustomed to a transaction and negotiation. I think that the thing he thinks about it, the stronger i look, the stronger people think i am, the more power i have. And he uses it. The less people would mess with him . Absolutely. But but, also, kim jongun has the same sort of opinion, that he has now Nuclear Weapons and he is a player, as well. Its a very precarious situation. It was really late or many hours difference in pyongyang. What do you think the reaction is tonight in pyongyang after President Trumps speech to the u. N. . Couldnt have been happy and well probably see a defiant response to that. Well probably see another Missile Launch very quickly and this is going to be a for tat kind of thing. Two completely different views. Senator Dianne Feinstein said the goal of the u. N. Is to foster peace and promote global cooperation. Today the president used it as a stage to threaten war. On the other hand, Prime Minister netanyahu said in over 30 years i have never heard a bolder more courageous speech at the u. N. I think both are right. First of all, what donald trump did today was say to the world, we are 22 of the budgeted of the United Nations and we have certain expectations about what the United Nations should be doing in the world. He called out various nations for their behavior. That is not something you see in these kinds of speeches. They are very deferential usually. The president goes and, you know, is very deferential, as i say, and magnanimous and so forth. Donald trump went to new york and was donald trump. Very bold, very direct and getting a lot of reaction. Absolutely. On both sides. Well leave it at that. Brian, thank you. Youre very welcome.

They say Justin Hermans name has come to the displace of people of color from the fillmore district and they would like to see a persons name that reflects San Francisco values. Its adopted unanimously. Reporter the San Francisco board of supervisors passing a resolution urging the sf rec and Park Department to rename Justin Herman plaza at the foot of market along the embarcadero. This is really not a resolution about demonizing him. Reporter supervisor aaron peskin who introduced it says the late Justin Herman was head of the Redevelopment Agency from 1959 to 1971. He says during that time, urban renewal displaced black and japanese communities in the fillmore and Western Addition neighborhoods. In the fillmore, over 4,000 individuals were displaced. 60 square blocks of a vibrant community were demolished. This happened under three mayors under countless boards of supervisors, um, under many, many Different Department heads. It was a misguided principle of the time. Um, and Justin Herman has come to symbolize that time. Reporter peskin wants the public to decide on a new name and julie a resident has recommendations.

A Spokesman Says sf rec and park is open to the idea and provided us a statement saying, quote, sf rec and park is working closely with supervisor peskin to conduct a Robust Community outreach to identify an appropriate name for the plaza. I think its time to acknowledge the mistakes that San Francisco made a half century ago, um, and to move forward. Reporter the resolution not only calls for the removal of the name, but it also wants to temporarily call this Embarcadero Plaza while public input is gathered on a new permanent name. Peskin says the rec and Park Department is set to take up the issue at their meeting next month. Thank you, Cristina Rendon in San Francisco.
