Ever wondered what happens when nature unleashes its full fury? Typhoon Haiyan gives us a terrifying answer - this Category 5 super typhoon struck Southeast Asia in November 2015, starting as just a simple tropical depression before becoming a monster storm.
The numbers are absolutely mind-blowing. Haiyan packed 230 km/h sustained winds for 10 minutes straight, with peak gusts hitting an incredible 315 km/h for one minute. The storm surge - essentially a wall of seawater pushed inland - reached over 5 metres high, which is like having a two-storey building worth of water crashing onto the coast.
Primary effects hit immediately and were devastating. Over 6,300 people died, mainly from drowning or falling debris, whilst 30,000 fishing boats were completely destroyed. The coastal city of Tacloban was absolutely flattened - more than 90% of the city was destroyed by the 5-metre storm surge, with 40,000 homes wiped out and 60,000 people displaced.
Remember Primary effects happen immediately during the disaster, whilst secondary effects develop over time afterwards.
The secondary effects created long-lasting problems across the region. Widespread flooding destroyed crops, affecting 14 million people overall. Disease outbreaks spread quickly, roads were blocked by landslides, and identifying bodies became so difficult that mass burials were necessary. Violence and looting broke out in Tacloban as 6 million people lost their income source.
Immediate responses came from around the world. The Philippines Red Cross had cleverly pre-positioned emergency supplies, whilst Canada and the USA deployed military aircraft for search and rescue operations. Over 1.1 million people received clean water from the Red Cross, and 1,200 evacuation centres provided shelter for the homeless.
Long-term responses focused on rebuilding better than before. The government launched a 'build back better' scheme, whilst the UNDP set up cash-for-work programmes that paid villagers to clear debris. Aid organisations helped replace the thousands of destroyed fishing boats, and massive vaccination programmes protected children from disease outbreaks.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend
